hey guys and gals...quick question, im having a high RPM and its throwin me a CEL. i replaced the iac valve and motor and still gettin the same code. i was thinkin next is either the throttle position sensor or the fuel reg....any opinions?? help is appreciated, also if i would go with the TPS, any suggestions on the easiest way to get it out, its pretty cramped back there behiind the throttle body, thanks,,,

 

Okay so what is the CEL exactly? Is it a code for the iac or something different?

 

its PO507....idle higher than expected

 

I would imagine there would be a code related to the tps as well if it was the culprit.
Try these solutions:
A vacuum leak
Leaking air intake after the throttle body
EGR valve leaking vacuum
A faulty positive crankcase ventilation (PCV) valve
Damaged/failed/dirty throttle body
Failed EVAP system

 

I'm getting this same code. i had my throttle cable kind of pinched in a weird way, positioned it differently and now its idling perfect. i also replaced the IACV and I dont think it was necessary because of the throttle cable being tweaked.
