Pontiac6KSTEAWD Posted April 20, 2005 Report Share Posted April 20, 2005 WOOT!!! Thats right all. I got the TGP out of storage today, and took it for a 30 some mile drive. First time I have ever driven it, or a turbo car (considering I have owned the car for 1 1/2 years, its about bloody time). That was something else let me tell ya. I have driven cars with the 3.1, and while its powerful enuf to move most cars along, its just not a "fast" car. As far as the TGP goes, once it gets past its little acceleration hick-up, that cars hammers right up to 70. The Imapala SS that was following me home had a hard time keeping up. It was actually quite interesting that I was able to get the car running, from pulling it out of storage, to getting it in my driveway 25 some miles away, in less than 4 hours. Topped off the gas tank with some premium, put some plugs and wires on it, and re-did the turbo intercooler setup as the clamps kept popping off under WOT psi boost. I also had to rewire the dual cooling fan setup as the previous owner got the wise idea to hotwire the fans so they run all the time. Not bright.. So thats the current update.. Jeff M. I will be ordering a X-Over and a 180 chip from you REALLY soon. Keep an eye posted for a PM from me would ya.. Quote Link to comment Share on other sites More sharing options...
Jeff M Posted April 20, 2005 Report Share Posted April 20, 2005 I share in your excitement , even though I have owned TGPs since 1990, they still do it for me, nothing else is so good at what all it does, every time I walk out to a parking lot to get into my car, I always enjoy looking at it, always good on the eyes 8) !!! Ready when you are, everything is in stock. Email is best. I would have suggested to study the spark plugs for signs that might help on the hickup, still worth looking at the old ones even if you don't know what cylinder they came out of, look for anything odd or different between them!!!

Pontiac6KSTEAWD Posted April 20, 2005 Author Report Share Posted April 20, 2005 Looking at the plugs on this one would have been pointless. Althou they were the right plug R42LTS, they were only gapped at .025. Nearly half of what it is supposed to be. Once I replaced the plugs and wires I was able to drive up and down the street without it stalling. And then able to drive home. It has this hick up from a stopped acceleration, or a hesitation at WOT. I am thinking the TPS has a flat spot in it or something. I was hoping it would throw a check engine code at me. But so far no lights (not even a brake/ABS light :shock: ). Jeff, can you send me an email or PM so I know how much in prices I am looking at. This way I can be sure to have all my financial ducks in order. Also let me know your ways of accepting payments (paypal preferred on my end). Also hook me up with that x-over disasembly tutorial again so I can be prepared. I guess I am also going to be needing the oil feed and return lines? or does that come with the package? Let me know man.. Quote Link to comment Share on other sites More sharing options...

Pontiac6KSTEAWD Posted April 21, 2005 Author Report Share Posted April 21, 2005 Well, we went thru the car yesterday to clean out the interior of stuff since the car also acted like a storage locker LOL. And the wife threw out something that looked like a diaper. I yelled at her to pull that back out of the trash. It was the heat wrap for the turbo and x-over. And it was in excelent condition. No signs of burns, velcro still worked everything. So theres another thing to look forward to when I install the X-over. Also found I have one turn signal out, big woop. The sunroof will pop up, and close from that position. But it wont slide back, any ideas on this? I dont have a low fuel light on, but on the DIC it says to cheack fuel. Whats the story here? Where can I purchase some key FOBS so I can have my RKE (assuming it works) functions. The tape deck radio I put in there in place of the OE CD Player dicided it wasnt going to work no more. So I have to install the CD player back in, and install a cd changer in the wifes car. Probly going to have to replace the exhaust from the cat back. One of the mufflers is leaking pretty bad. I am just going to be going OE. This car will never see the track, and probly not even a street/highway race either. This is the first W-Body I have ever driven, and it drives so SMOOOOTH!! I just purchased some KYB's also.. Quote Link to comment Share on other sites More sharing options...

I never heard of the gap shrinking but I could not be happier in finding this out when it fixes the problem 8) 8) , I love easy fixes I don't care what they are. Hickup, might want to run an injector test, started a page with detailed info like this: http://www.turbograndprix.com/FixIt.htm Jeff, can you send me an email or PM so I know how much in prices I am looking at.

Let me know man.. NO, you email me first actually from my web site gets to me and I can then reply to your email with the price breakdown and pipe install doc (PMs don't allow attachments :oops: ). Got PayPal too 8) . The oil return is the one that goes bad, stock those at $15 each, high-temp silicone, not your typical hydraulic rubber 8) . Nice you still got a decent condition diaper, and that the wife learns it don't stink to keep wearing it . Jeff M Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted May 22, 2005 Author Report Share Posted May 22, 2005 Well, heres the update... Got the car licensed and titled over the weekend (cost of 300 bucks for that).. Put in a new windsheild for $$100. I tried to get them to put in a HUD Specific windshield, but their werent any available... ANYWHERE! Installed new struts. Boy I had no idea how bad they were (680 bucks) Installed some new Yokohama's v rated tired (400 bucks) Removed TGP coolant overflow bottle, and installed one off a 5 speed z-34 from junkyard ($$10). Installed new AC Condensor ($154) Radiator flush ($$20) Transmission flush and Filter ($104) Replaced Alternator ($130) Installed K&N RU-1390 and breather filter ($45) Welded up the rear Y-Pipe as it had cracked ($42) So I put in just around 2400 bucks over the weekend... Man I feel broke!! Next 7 things left Replace rear calipers and rotors with 95 model Grand prix (new) Replace X-over with Jeff M unit Replace Distributor delete O-Ring Replace 02 sensor Get Moonroof fixed so it slides back Get AC Charged Replace EEPROM with 195 Chip from Jeff M (decided the 160 would get me in trouble). I am beginning to wonder if this car doesnt already have a Jeff M Chip already in it. I would think I would be getting overboost from the K&N air filter being on there. But that thing just keeps accelerating, at WOT, all the way to redline. BOV is funtioning perfectly. The coolant temp never gets above 160-180 according to the stock guage. and never above 220 (even when racing down the highway at WOT and doing 125). Jeff is there a way to tell whether or not I already have your chip, and which one it is? I am having 4 guage related issues. 1) Tach is WAY off. when it shifts at redline, the tach reads about 11000 RPM. Althou that would be cool, maybe :? , It obviously isnt true. 2) The second guage is the Speedo, it is progressively off. At 35 MPH, I am going 30, at 71 MPH, I am going 60, etc, etc. 3) The 3rd guage issue I am having is with the DIC. When I top off the gas, the DIC reads "CK FUEL". But no yellow light is on my dash (which does work), and the guage reads full. It only does this for the first 25 miles of driving after top off, and then goes back to normal operation. 4) The forth guage problem is the boost. I am not sure if its the guage, or some sensor in the intake, but sometimes it works, most of the time it doesnt, and stays right around -10 boost. I would love some help on those issues. Althou I think the speedo and tach is just run of the mill issues with the TGP. The HUD and Odometer are dead on. Other than the empty wallet, the wife wondering when we will have money to guy some new clothes, everything is going great!! Now I just need to track down that elusive TGP Specific windshield washer bottle. Quote Link to comment Share on other sites More sharing options...

Jeff is there a way to tell whether or not I already have your chip, and which one it is? It mostlikely doesn't have the chip in it. In my STE and my dads TGP, the temp gauge will be at the first line when it is fully warm, the gauges aren't too horribly accurate. When they were stock it would go up to the 2nd line (I believe its around 180 somewhere maybe, can't remember???), so I thought the same thing. Neither of them overboosted with a K&N and the stock chip either... If you pull the chip out and it is a Jeff M chip, it should say so right on the memcal. It will say like TG160 or something to that effect on it. Shawn Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted May 22, 2005 Author Report Share Posted May 22, 2005 Oh yea, I am also getting a respectable 20.2 MPG. Not to bad considering it does have the bad X-over and O2 (which amazes me that it passed a sniffer inspection like that). Quote Link to comment Share on other sites More sharing options...

Not to bad considering it does have the bad X-over and O2 (which amazes me that it passed a sniffer inspection like that). Oh yeah? Hmmmm..... *Scratches chin* I was afraid to attempt the emissions test with the cracked x-over pipe. It may possibly have a bad cat, too (more then likely). But maybe I WILL give it a try regardless, since yours passed. Quote Link to comment Share on other sites More sharing options...

But maybe I WILL give it a try regardless, since yours passed. A little more thinking to explain what happens here but; what can happen sometimes but not always with running a cracked pipe for a long time is the o2 sensor as it becomes fouled is no longer reading correctly at all. And with some o2 sensors and the driving habits of the owners is the fouled o2 reading no longer sees this extra air from the cracked pipe, and the ECM starts to lean back out the fuel trim. Problem is the o2 sensor is still fouled so its reading is not helping trim the engine proper the rest of the time and on a scan tool would look slow and lazy and most likely not reaching the full rich/lean transitions it does when healthy. But the bottom line is the o2 sensor is no longer reading the effects of the cracked crossover, but is also not reading the engine accurately either, so it could be a hit or miss when trying to pass emissions.

dbtk2 Posted May 23, 2005 Report Share Posted May 23, 2005 When I got my STE the previous owner gave me the results from the very recent inspection he had done on it (MI doesn't need inspections so I didn't care, but did find the results interesting) but it passed the sniffer by a longshot. I don't remember the exact numbers, but lets say the limit was like 150 whatever they measure, it was like 21 or something...it was way low, and the car was completely stock, stalled at every stoplight, etc.... It was in no good running order to say the least. (although it pulled 14.9's like this so maybe it was?) I was amazed to say the least.

90tgpblk Posted May 23, 2005 Report Share Posted May 23, 2005 Brian, I do think I have the washer bottle out of my TGP. I removed it to put on a red top optima batt and some custom plexiglass work over the battery and it would not fit and I just left it off, since I very very rarely drive it in the rain. If you still need it I will be able to get it this coming weekend. Just post back or PM me. Ken Quote Link to comment Share on other sites More sharing options...

Pontiac6KSTEAWD Posted May 24, 2005 Author Report Share Posted May 24, 2005 Well I took some pics of the car after all the fixes and part swapping. it drives like a scalded ape, althou I think the FPR or Fuel Pump is getting weak. Will have to wait until I get some funds built back up in the account befor I can fix anything more thou. So on with the pics The money shot... (rest are links) Looks damn good considering it looked like this befor.. http://img.photobucket.com/albums/v295/LaPurr/89%20and%2090%20Pontiac%20Turbo%20Grand%20Prix/Befor%2090%20TGP/Befor_90TGP1.jpg http://img.photobucket.com/albums/v295/LaPurr/89%20and%2090%20Pontiac%20Turbo%20Grand%20Prix/Befor%2090%20TGP/Befor_90TGP2.jpg http://img.photobucket.com/albums/v295/LaPurr/89%20and%2090%20Pontiac%20Turbo%20Grand%20Prix/Befor%2090%20TGP/Befor_90TGP4.jpg So here are the rest of the current pics... http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200029.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200028.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200021.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200020.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200019.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200027.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200017.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200015.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200014.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200016.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200022.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200023.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200024.jpg http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200025.jpg This is a shot of the oil feed or return line (not sure which one is which to be honest. It looks like it was recently replaced, but I could be wrong.. http://i4.photobucket.com/albums/y137/Smurflemouse/90%20TGP%20After/S4200026.jpg So I would say she is shaping up quite nicely. Althou the Distributor Delete Plug O-Ring is leaking like a mo-fo. And I am not going to replace it until I can do the X-over and AC Recharge at the same time. So I have to save a little bit of money befor that can happen.. Let me know your comments opinions and suggestions.. And for those who are wanting to know, yes my steering wheel controls work with the aftermarket radio... Quote Link to comment Share on other sites More sharing options...
90tgpblk Posted May 24, 2005 Report Share Posted May 24, 2005 Brian, I am thinking that shipping will be about 5-10 dollars. So if 45 shippped is good for you then its yours. Ken Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted May 30, 2005 Author Report Share Posted May 30, 2005 Alright, have a new problem. When the gas tank is full, the car accelerates incredibly, no hesitation, no nothing. Once I put about 100 miles on the tank, I start getting a off idle from a stop hesitation. I am thinking the FPR, but I dont see how that would do it considering it only works off the fuel its given. Which should be the same regardless of being empty or full. Ideas on this one? Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted May 30, 2005 Report Share Posted May 30, 2005 i'd say fuel pump. try hooking up a fuel pressure gauge to the schraider valve on the fuel rail and run it up to the windshield while you drive and see what the gauge tells you. btw that braided line in the last pic is the oil feed line. the oil drain hose is below the coilpacks and is about 5/8" in diameter IIRC. car looks wayyyy better than it did!

Pontiac6KSTEAWD Posted June 2, 2005 Author Report Share Posted June 2, 2005 Well, I spent all that money to get the TGP out of storage and driveable... Then I lost my job yesterday. Company sold out tuesday morning, and then fired everyone, nationwide. 1700 employees in all. So, I got a new job today, but its truck driving with a income of 1200 a week. So, TGP goes back into storage LOL.. One way to keep the miles off it.. Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted June 19, 2005 Author Report Share Posted June 19, 2005 Well a small update of sorts. The distributor delete O-Ring went bad. Had been bad since my first oil change. It began dumping out about 1 quart every 10 minutes. Little to unsafe to drive like that. So I replaced it today, took about 3 hours, and that included 1 and 1/2 hours of power washing to get all the old oil and dirt and grime off the motor and tranny. No more oil leaks, Sweat...
