Hey Everyone;

Has anyone ever had a idle issue with there C5, I have a reoccuring idle problem. When the cars warms up and I come to a stop the idle jumps up to around 1200 rpm, then on the way down to around 850 to 900 it just goes away and stalls.

I have the fast intake and the hitech thottle body on the car and have had the tunner look at this three times. I have heard that you shoud use the LS2 throttle body but the stories vary. Just looking to see if anyone has had this issue.

Thanks,
Mike D.:thud:

Hi Mike, The first thing to do is see I you have thrown any codes. That would help pin point the area

Make sure the seals on the intake aren't leaking, (sucking in air) too much air will cause the idle to rise and then drop very slowly. Just my .02.
