Well i have my turboed n/a running and when i go to crank it it idles fine, but after some driving and boosting, it likes to stay really high. My tach doesn't work right now but i know the trailing coil is working, but also the temp, gauge goes straight up whrn the key is in the on position. I don't have any emissions on the engine and the cold start removed. Does anyone know what could be causing this?

 

Could it be the swicthing actuactor sticking and causing it to stay reving up?

 

no one has ran into this?

 

hah today was the first time ive heard the stock blowoff valve so loud.

 

I too have this problem.

 

same problem with temp gauge,key on engine not running, maxed out, car running it goes all the way down even wen warm.

also my idle generally stays at around 1500 warm, and like 2200 cold.

anyone know what this might be?? a couple times i got the idle to go down to 750ish but hten it jumps up after driving.

 

Perhaps you have a sticky throttle cable?
