GrandPrixLover2 Posted July 28, 2009 Report Share Posted July 28, 2009 Here are two pics, one is of my throttle body, and the other is looking into the intake manifold. As you can see both of them are extremely dirty. Right now I'm only cleaning the Throttle body, and what I can of the UIM. But when I get more money and time, I will take the UIM off and clean it as well. This hasn't been done since I've had the car and I figured now would be a good time with jmust having done a routine tune up on her. Here are some pics of the CARBON BUILDUP inside the throttle body, and UIM. These are links to a facebooko page as I have forgotten how to post pics on here :-( : (Throttle body) http://www.facebook.com/photo.php?pid=2351114&l=a62274e750&id=603321686 (UIM) http://www.facebook.com/photo.php?pid=2351115&l=863d505d3e&id=603321686 Quote Link to comment Share on other sites More sharing options...
Andrew Posted July 29, 2009 Report Share Posted July 29, 2009 damn! make sure to remove the sensors before you clean it so you dont ruin them/gunk them up. Quote Link to comment Share on other sites More sharing options...
GrandPrixLover2 Posted July 29, 2009 Author Report Share Posted July 29, 2009 yeah, I didn't remove the sensors but I made sure I had everything cleaned out. Here are some after pics.

sloick Posted July 29, 2009 Report Share Posted July 29, 2009 why would you remove the throttle body to clean it? you should bypass the coolant to the throttle body while you have it off. Quote Link to comment Share on other sites More sharing options...
GrandPrixLover2 Posted July 29, 2009 Author Report Share Posted July 29, 2009 why would you remove the throttle body to clean it? you should bypass the coolant to the throttle body while you have it off. I had to gain access to the rear of the throttle body which is where the majority of the carbon buildup was, on the rear part of the throttle plate. That's why I had to take it off, that and the carbon was just caked on it BIG TIME, and I meanBIG TIME, lolz. And what do you mean by bypassing coolant to the throttle body while I have it off?

sloick Posted July 29, 2009 Report Share Posted July 29, 2009 you can open it while its on the car and spray throttle body cleaner and uas a rag. it comes right off with a rag. nevermind about the bypass. Quote Link to comment Share on other sites More sharing options...
Venom Posted July 29, 2009 Report Share Posted July 29, 2009 you can open it while its on the car and spray throttle body cleaner and uas a rag. it comes right off with a rag. nevermind about the bypass. x2 thats what we do at work for the induction cleaning. The spray we use is pretty strong stuff and the build up comes right off with a rag or a pipe cleaner. Then we hook up the intake manifold cleaning solution to a vacuum port and let it run through the car until its gone. Quote Link to comment Share on other sites More sharing options...
GrandPrixLover2 Posted July 29, 2009 Author Report Share Posted July 29, 2009 Huh, I will definitely try that next time. Thanks for the advice. I'm fairly new to working on cars but my Grandpa, my brother(who absolutely loves cars), and various other people in my family have been teaching me whats what, and what not. So I know a little, but I'm still learning. I eventually wanna get to where I can work on my own car with out having to take to a mechanic unless it involves timing, and other advanced issues like that as well. And I am right now going to post pictures up of my car while I was working on her and I took some pics of the morning after(this morning). Those will be in the Appearance/car care section of the forum. Quote Link to comment Share on other sites More sharing options...

slick Posted July 29, 2009 Report Share Posted July 29, 2009 I did the spray stuff into the throttle body while it was on the car, and it helped. But nothing beat taking it off, and finding all of the carbon buildup on the backside. It was causing a sticky pedal situation. Afterwards, the throttle was smoother than before, and seemed to idle ever so slightly better too. Quote Link to comment Share on other sites More sharing options...
GrandPrixLover2 Posted July 29, 2009 Author Report Share Posted July 29, 2009 Yeah I replaced the gasket. The old one was too brittle, and I broke a corner of it off when I was handling it and I was like uh yeah I'm not putting this thing back on. So I went to Pep Boys and got a new one. I was also wondering, how do I go about cleaning the UIM, because when I had the TB off I could see major carbon deposits inside, also inside the tube that leads to the EGR valve, right at the mouth of the manifold. I have seafoamed the UIM, but that hasn't seemed to clean it completely out. THanks for all the help. Quote Link to comment Share on other sites More sharing options...
slick Posted July 29, 2009 Report Share Posted July 29, 2009 Best bet, pull it off, and dip it in a parts cleaner bucket. Quote Link to comment Share on other sites More sharing options...

DavidHowell3633 Posted July 29, 2009 Report Share Posted July 29, 2009 I just used Berryman's for the first time. While it's less expensive than Gunk, it seems to work just as well. Quote Link to comment Share on other sites More sharing options...
pitzel Posted August 10, 2009 Report Share Posted August 10, 2009 a) Don't bypass the coolant through the throttle body. You never know when you might be operating the vehicle and throttle body de-icing is required; The throttle body probably got gummed up because you changed your oil too often with crappy oil. Try and use the least volatile stuff you can buy, and don't change it every 3000 miles or 3 months, but rather, go at least 7500mi (as the owners manual says), or a year or two.

No. The carbon buildup is from your EGR recirculating exhaust gasses through your upper intake manifold. If this was oil-related, you'd have noticeable oil consumption going on.

No. The carbon buildup is from your EGR recirculating exhaust gasses through your upper intake manifold. If this was oil-related, you'd have noticeable oil consumption going on. Its not so much of an issue with modern oils, but the older oils used to have much higher volatility, in other words, over the first few thousand miles, they'd experience quite a bit of evaporation. Much of that evaporation ended up in the intake, through the PCV and/or front valve cover breather. Mainly happened with new oils of relatively low quality.
