How to get rid of "Idle higher than expected" code. I recently installed an LS6 intake and 218/222 .562 .562 cam in my 1998 Z28 A4 2.73 car and I had some idle problems with it. It wouldn't idle, so I started drilling with a 3/16 drill bit, and then, stepping up to a 7/32 and now it idles fine. Problem is now I get this "Idle higher than expected" code. It is idling between 800-850 RPM in park and about 800 in gear. My IAC pintle counts on ATAP are like 1-10( I think it should be like 20-50???). Is there something I can do, or will I have to get ls1edit to raise idle speed so the code doesn't trip. We have OBDII computer emission testing here and they won't pass me unless my service engine light is off.
Thank goodness it's nothing serious...lol....
