idle question and iac's with ls1edit...

ok, if the car is running too rich at idle, im supposed to drill a bigger hole in the throttle body and lower the idle from the pcm with edit right? what is a good range of iacs for idle? thanks!

On a manual car IAC between 30 and 50 work good.

On an automatic car IAC between 60 and 90 do the trick.

Good Luck,
Kevin

Kevin,

Are those IAC counts for when car is in park or in gear for an automatic?

Thanks,

Tom

Those are in park.

In drive, or with the engine under some form of load (ie AC), I try to get them to 100-110.
