'99 996 Rough Idle Smoothed Out

[iflyjets4u]

I have struggled for some time with the rough idle on my car. Some of the techs have said that mine is worse than others, but all '99's are not smooth.

I saw this post: http://www.renntech.org/forums/index.php?showtopic=3595, where the member had a problem with his car stalling at idle.

In the post, Loren suggests that a carbon build-up in the throttle body was the problem. I checked out my throttle body, and found that it was fairly dirty. I cleaned out the throttle body, as suggested in the above thread and found a noticeable amount of improvement.

Although it is not perfect it seems to be much better.

Hope this helps some of you out there.

Does someone have a picture of the throttle body? My 99 has intermittent rough idling, so this may be the cause.

Cheers and Merry Xmas
