High Idle When Warm

[AwdGSX13]

since you have the block off plate, its not going to want to idle normal. At least mine doesn't it idles like shit until warm then its perfect.

*Edit*
This is assuming to removed the FIAV and IAC.

Check your Base Idle screw and you can try adjusting the throttle body blade with the closed throttle position bolt (under the one wire harness, back side of throttle body)

Problem existed before TB block off. It causes the rough cold start, but not the rising idle.

Biss has been adjusted every which way. That just shifts the idle range as it should (so I could bring cold idle from 700 rpm to 900 rpm, but once it warms up it would just go from 2000 rpm to 2200 rpm).

Can you elaborate on the closed TB blade and bolt. I'm not familiar with it. Does it just adjust like the BISS? What does it control?


*edit* Anybody know anything about the exhaust ground strap. I read that could effect the O2 operation which could in turn effect idle. My car has never had one.
