GIANT MOTH Posted January 14, 2007 Report Share Posted January 14, 2007 This has been happening for awhile with my 95 GP 3100. When I come to a stop the engine starts losing it and once in awhile it stalls. It definately happens when I make a sharp 180. I can pedal it up to get the engine going and that always sort of works before it goes dead. I was thinking my belt tensioner was shot but the way things are I think this is leading to that friggin bad quad driver. I'm guessing my torque converter or its controls are chooched. Anyone got a clue? Quote Link to comment Share on other sites More sharing options...
Philsz34 Posted January 18, 2007 Report Share Posted January 18, 2007 hey i had the 3.4 grand prix so its a lil diff from yours but mine use to the same thing. also when i hit the directionals the lights were flicker. stall all the time especially stoppin and turns. my problem was my power source next to my fuse box. it melted the plastic covering. i called it my third terminal. im not sure if thats your problem but that was mine sorry if it doesnt help.

Andrew Posted January 19, 2007 Report Share Posted January 19, 2007 have you checked the tranny fluid level? make sure your car is fully warmed up before you check it. if its low your converter cant does its job right. Quote Link to comment Share on other sites More sharing options...
DOHCRagtopguy Posted January 19, 2007 Report Share Posted January 19, 2007 I had a similar problem in my Olds 3.4. Turned out to be the Idle Air Control valve. I put a new one in (2 torx screws) and problem solved. Quote Link to comment Share on other sites More sharing options...
zx21 Posted January 19, 2007 Report Share Posted January 19, 2007 If it does turn out to be the IAC, careful of the torx screws, BOTH of mine twisted off when I attempted to remove them... sucked. Quote Link to comment Share on other sites More sharing options...
GIANT MOTH Posted January 20, 2007 Author Report Share Posted January 20, 2007 I had a similar problem in my Olds 3.4. Turned out to be the Idle Air Control valve. I put a new one in (2 torx screws) and problem solved. That's interesting. Thanks. I actually have a spare IAC around somewhere. It just may do the trick. I remember buying it along with a throttle control awhile back. Not to sure at this point. I'm about to yank my engine out to seal it up again and redo my heads. . . . and rebuild my torque converter. Something like that. Why? Because I still play with cars that's why. Trust me I know everything there is to know about Torx bolts. If anyone else has any other insight that's cool. Quote Link to comment Share on other sites More sharing options...
GIANT MOTH Posted May 22, 2007 Author Report Share Posted May 22, 2007 Can anyone relate to any of this? I've installed a new IAC. (http://www.w-body.com/forum/index.php/topic,56523.0.html). Now the IAC helped but this still happens . . . When I got the car warmed up and in park (at night) I got the lights on. I step on and hold the brake down or really stomp of the brake. The RPM drops and stumples below 1 then levels out (as well as letting off the brake). I can see fluctuations in the dash lights when this happens. I can do it several times and it pretty much happens everytime. It won't stall in park. The car stays running but I've rode it out a few times with it stalling out on me when I'm coming to a stop. It won't startup again until (I'm assuming) the starter cools down. It won't turn over. After about an hour it will start up again. The IAC, TPS, starter, alternator are all new. The crank position sensor and just about everything else is new. the car runs great like everything is tight. I just have this electrical problem (?). I put a ground wire kit on the battery. This seems to keep it from not completely stalling out when it's in park. I'm not sure if this is a bad ground or another sensor and I'm not sure how to diagnose this problem at this time. Would the starter do this? The starter I used fits the vehicle but is specified for 2001-2003. Not sure if a starter can be "too powerful". Maybe the ignition switch? The air control sensor thingamajig behind the coils? New coils? What's going on here? It would be great to hear from any of you who have experience with this related problem or had similar issues. I really don't want to fork out the cash for a shop to fix this because I have my doubts that they can fully diagnose the problem or even consider fully diagnosing the problem.

Crazy K Posted May 22, 2007 Report Share Posted May 22, 2007 applyi9ng the brakes can be a double wammy on the car. the sudden draw of the booster when you press on the brake lowers the RPM.... and the brakes lights illuminating create a electric spike... the draw of energy makes the alt worker harder. Now here's a good question... if you are driving at night and you apply the brakes, do the headlights momentarily dim? have you checked to make sure the auxiliary post bolt is tight?

GIANT MOTH Posted May 22, 2007 Author Report Share Posted May 22, 2007 Yes on occasion they do. I can remember after seeing my headlights dim the stalling starting to happen. Are we talking the fuse box by the ECM? I'm sure that's ok but I'll check over it. The alt is new and the bolt is tight. The other positive lead by the battery is ok.

Crazy K Posted May 22, 2007 Report Share Posted May 22, 2007 I had the dimming issue on a car, and it turned out it was due to a bad voltage regulator in the alt. you should get it tested, new or not. Quote Link to comment Share on other sites More sharing options...
GIANT MOTH Posted May 22, 2007 Author Report Share Posted May 22, 2007 Sounds like a plan. I'll be back later. Thanks. Quote Link to comment Share on other sites More sharing options...
