ok my idle sticks to 1500, no vacuum leaks, I tried adjusting everything adjustable. I have blocked everything off, nothing controlling the idle. I am running microtech.... I dont know what else to do, but switch to the n/a TB that has the idle screw and see If I can controll it with that..

 

Are you sure the mechanical idle isnt set too high? What about the throttle cable being kinked or too tight? TPS and timing set correctly?

 

timing is fine, everything is fine. I removed my cable to see if it was the cable... and nope. What mech. idle are you refering to ?

 

Idle stop screw (I think that's what it's called). It holds the throttle plates open.
