Rough Idle
 

I have a 2001 Boxster, the car only has 15,000 miles on it, I recently had a new clutch installed and the rear main seal replaced, Before I had all this work done the car ran perfect but now when I start it the car runs really rough until the car comes up to temp. and then idles perfect, the car sat for a good period of time. I really hope somone can help me, my mech. skills are limited.

Thanks Mike

Did you try cleaning the throttle body?

I'd take it back to the place you got it fixed. Could be a leak or sensor problem, maybe they didn't connect things properly.

Is the check engine light coming on?

No check engine light, I also had the mech. take a look at the car after the repairs were made and he told me that there was no way a clutch replacment could cause a rough idle

Should I try Gum Out first????????????? Or is there a better product out there????

And Thank You All For All the Help.... I'm very concerned...

New clutch at 15k??

The dealership suggested that I replace it while the trans. was off the car for the RMS replacement. The old clutch had about 20 % of life left. According to the dealer.

Last night I removed the throttle body and cleaned the carbon build up out from the butterfly valve, I was hoping this would do the trick but when I restarted the car I had the same issue's, a rough idle until the car is warmed up. Does anybody have any more suggestion ??? I could really use your help!!!!!!

I just did a search on here with the phrase "rough idle" and found quite a few. Look under

check out the "cold starting" thread.

With 15k miles and if it worked fine before and now it doesn't, process of elimination says something happened. I know **************** happens sometimes but probability says it was them and not chance. I doubt you all of a sudden got carbon build up. It sounds like something computer or system related. Possible o2 sensor. I changed my plugs(probably first time) at 60k miles and that fixed my slight idling problem.

Good luck and don't take no for an answer :cheers:
