Idle Problem

Postby Regie » Sat Mar 05, 2011 12:01 pm

My 01 8B seems to have a strange intermittent idle problem.

happens once or twice a week after i have installed my SMB intake.

When i start her up when its cold it idles at about 2000rpm or just above, when she is warm it starts idle hunting form about 1500-2000rpm. I then let it cool down over night, then it doesnt happen for another few days.

Ive cleaned up the throttle body with no success. I also disconnected the ISC plug when its warm with no success.

Is there any other ideas as to what it could be.

Thanks guys

I had the same issue but not intermittent
It was the Idle Air Controller
There is a bit of a story and an article on how to clean it HERE

NB8A and NB8B have the same IAC
