My idle sucks and it takes 3-5 starts for the engine to even idle when cold. I usually have to give it some throttle to keep it from dying when the engine is cold.
I tried replacing my IAC to no avail. When I disconnect the IAC the engine RPMs surge. I thought it was supposed to die.
My EGR was removed with no CEL. Only code 33. I don't see any vacuum leaks. I've got 36lb injectors, 36psi fuel pressure, PRO M maf, vortech 12 psi sc, AC removed.
I checked my TPS signal it reads 0.6V when the key is on and the engine is off. I guess that is low. But I don't have a CEL. No engine running codes.
I can't turn the TPS on the two screws enough to get the .9v. Is the low TPS signal causing the rough idle. The only way I can get the .9V is by turning the idle up to 2000 RPMs.
Any ideas?
Thanks
Tom
