The AIT valve is killing me, need help Cam experts
Just installed the Hammer cam and I have drill the throttle body to 13/64 and the car idles good for about 2-3 minutes and then the AIT valve starts trying to adjust idle.
Is there any way to fix/mod problem.

I'm not an expert and my cam is less aggressive than yours, but what I did was drill the TB to 3/16, which your already one size larger, and raise the idle bump stop screw up to were it idles at 700-730 RPM. That brought my IAC count from 70 down to 35. No more surging and no more dying <img src="images/icons/smile.gif" border="0"> only other thing I can think of is custom PCM programming...

Re: Thw AIT valve is killing me, need help Cam experts
I spent a few months driving and fine tuning my idle speed after my Hot Cam install. I would make a small adjustment, then drive it a week or so to let it learn. In a nutshell, after drilling the TB to the point where it was close, I fine tuned the base idle speed to where the IAC was in the single digits with all accessories off and the engine at operating temperature.
