did the cleaning over the weekend and it worked!!! amazing difference... like driving a new car.
now can someone please explain to me (pics would be nice) how/where to install an oil catch tank? |
im seriously going to try this tomorrow
*EDIT* Cleaned out the TB and i can honestly say that it works very well. i wouldnt mind cleaning it every few thousand miles. its such an easy process thanx so much! |
Does anyone have pics of this being done to a 2007 2.0SC?
thanks |
Wow, I was just browsing the forums and came across this. I have no problem like this on my Cobalt, but have been avoiding driving my 02 Blazer because of this.
Actually just took it off about an hour ago, cleaned it, put it back on, and it started right up and idled steady for the first time in like 2 months. Feel like such a dumb ass for not being able to figure that something like that was the problem. Thanks alot for the help. |
My idle didnt bother me that much before but i did it anyway. The difference is huge. Thank you!!!

I did this over the weekend and it worked perfectly thanks again

Much like most of the feedback for this post, great results from this fix. Thanks a lot.
Don't know if anyone has beaten me to it, but here's some detailed instructions: Tools: Ratchet Short Extension~ 10mm Socket Flat Head Screwdriver Throttle Body Cleaner Wire Brush~ Instructions: 1. Unscrew the flat-head screw that tightens the clamp around the air intake tubing that connects directly to the throttle body on the right-hand ( driver ) side of the hood. 2. Unscrew the flat head screw that tightens the clamp at the other end of the above mentioned piece of tubing, it is actually a part of the next section of tubing but you will be pulling out the closer piece. 3. Remove the air intake tubing section from the throttle body and the second section of tubing. 4. Remove the fuel line that attaches to the side of the throttle body by pressing a small clip on the bottom of the line toward ( I think? ) the throttle body and moving it to the side, this will release the locking mechanism and allow you to pull it away from the throttle body with ease, this shouldn't be a struggle and be sure to be careful with the line, as it is fairly fragile. 5. Remove 4 - 10mm bolts that secure the throttle body to the supercharger, and disconnect the wiring harness. The harness is a bit tricky, I recommend a small flat-head screwdriver or a small, angled pick. 6. Separate the throttle body from the supercharger slowly, and be careful not to rip or tear the gasket between the two. 7. The fitting on the throttle body that the fuel line connected to is linked to a small port inside the throttle body on the supercharger-side of the butterfly. Spraying some throttle body cleaner through the port will do most of the work that needs to be done. I recommend taking a wire brush and some of your throttle body cleaner and spraying out the inner wall of the throttle body, as it ( if yours is anything like mine ) will have likely built up some measure of grime that may either continue to clog the fuel port, reduce air flow, or constrict movement of the butterfly. 8. Once you have cleaned the throttle body to your approval, and made sure that the fuel port isn't clogged ( blow some air through it and make sure that it comes out the other side freely ), re-attach it in the reverse order mentioned above, and viola, your problem is fixed. If anyone has any comments or things I might adjust in this post please let me know, and thanks again to whomever started this post, easy fix to an irritating problem. Much appreciated. |
i went to a auto parts store and was about to buy the throttle body cleaner until i read the back of the can, it said do not use on cars that have superchargers, turbos, and so on. what brand did you guys use?
|
Just use a silicone spray...
|
i just cleaned it this morning, man what a difference it made. i always had the problem of stalling the car at a light when the a/c was on, now it stays put when i come to a light, driving like that for a year and all it needed was to be cleaned, thats a year of frustration down the tube.
|
So when im cruising at about 50-55 and i throw it into neutral before a stop light and coast to the stop light, (the AC is on idk if that matters) and it dips from about 500-1300 ish rpm, means i need to clean the throttle body out? Should I just alert the stealership when i drop it off?
|
yea you need to clean it, its real easy no more worrying about the car bogging when the rpms drop so low
|
i just cleaned mine tonight. i will find out tomorrow when going to work.
the throttle body cleaner i bought mentioned nothing about not using on a s/c or turbo car? |
subd

this works perfect! no more idle problems.
THANKS, |
Idle Problems
Im for putting a catch can on my pile of shit.. I have had the same issues.
|
Wow, Im soo glad to help soo many people out here. When this problem first happened to me I was talking to a buddy and said "I sure hope someone in North America can post something on here how to fix this damn idle problem" and then a few days down the road we went through possible areas that could cause this and when we finally figured out that the tb was fairly gunky at only 8,000km on her I realized this was the problem, so we cleaned it and the rest is history. It def looks like my thread has helped thousands of people out which gives me such a great feeling of accomplishment for such a small fix.lol. Anyhow, just for you guys out there wondering about the tb cleaner that says not to use on supercharged engines, dont worry about this warning as the best way to clean the tb is to remove it from the vehicle itself. Its a very quick thing to do and this way you are able to clean it thoroughly rather than half assing this therefore you dont have to clean it as often. Also, catch tanks are a very good solution to help fix this as the can will collect most of the gunk that is making its way to the tb.

"how to" info from post #257 should go on the 1st page under the issue.

I'm gonna try this tomorrow. I took it to the dealership and seems like they were speechless, but Im gonna try it ASAP. Thanks alot guys for the advice. I appreciate it.
|
Ok I tried, took me 30 min to clean the TB. Started it up, left it running for like 5min. Didn't fix the problem but thanks for the advice. It stills idles the same way and when I put the a/c it drops even lower. fuck my life. Anyone know how to fix this.

I have an AEM dryflow filter, so I didn't think this would help me much but I tried it anyways. Just got finished, and damned if my idle isn't back to it was the day I bought it off the showroom floor! Thank you! My tb wasn't as dirty as some of yours probably was, but still pretty gunky for only having 34k on her.

It's like that when you are tuned, just get used to it, why do you think GM deleted the AC from it's stage 3 tune!

I am having the same issue with my 07 SS. The problem was amplified by a stage 3 zzp kit I just installed. I tried cleaning the throttle body but no dice. I have a new throttle body arriving today. Hopefully that will fix the issue. Will advise as soon as I get the new one on.
|
Everyone go out, take the four bolts out, and clean your TB right now. I was soooooo stressed about this problem. It was the only reason my Cobalt was pissing me off. Problem sol-ved!
