Wasup! I have a fastback 1993 and I just had the engine re-manufactured. I also deleted the egr no need for it if you have a good cat. Anyway my problem is that I can't bring my IDLE RPM's any lower than 15 or 13. I have mess around with the idle screw to no joy. The timing is at 20. I played around the TPS and even with the Dis. I just can get it to calm down this car just want to go out there all hyped up!!! Will it be a new TPS? Anythng that you guys came come up that U have not done hit me up. Just cant wait to take this bad boy out there for the summer.

You either have some kind of Vac Leak or the IAC is no good.

You'll have to "smoke" the system if you or someone you know can do such a thing, or go around with a can of brake clean while it's running and spray all around the intake manifold until the idle changes.
