2008 civic si idle problem    (Score: 1, Normal) 03-23-2012 00:13

I recently cleaned out the throttle body on my 08 si 2 weeks ago. Now the idle is unstable. When I come to an idle the car rev to 2000 rpm comes down back up to 1500 back down back up to about 1200. Sometimes idle at 1000 and sometimes 1500. I've check for vac leaks, I beleive all hoses are routed correctly. I check vac leaks with propane around all hoses, ect. Even put on a new MAF sensor but no luck. Can somebody tell me what I'm doing wrong.

I'm not answering to your problem here.
When you ask, it all up to you to get how good an answer you could get. Simply because we don't know your car, we can't see, touch, smell(I like to), etc. Just like computer problems, "Why didn't you tell me that before!?"

In this case, what did you do to clean your throttle body? 'clean' could mean anything to people. Did you do it yourself or had it done? Why did you do it? There must have been a reason to clean it. Rough idling in warm-up and/or after it's already warmed up. How about maintenace items? Etc, basic stuff because you knew that but nobody else does.

Nobody has time to go back and forth. So more you tell better chance you'll get an answer from someone, I think.

Sorry, I got no clue.
One of basic things I used to do for anything was that I'd make sure the battery and its posts are clean and fresh, because everything works on electronic something nowdays. And vacuum stuff becasue I used forget those things, often. Good luck.

yeah, just to add to the final thought by CR-V9, my s2000 would sometimes have trouble idling and even running at low rpms and I'd have to goose the throttle to keep it running for a while, then one day the battery went completely dead and I had to get a new one. After that my idle and low-rpm problems were completely cured.
