Your (check engine light) CEL is on. Pull the codes as described here. Post the codes that you retrieve.

Did you calibrate the TPS after you installed it?

Dis you reconnect all of the vacuum hoses and bleed that cooling system after replacing the IACV?

dcneo

the code that keeps coming up is for tps which is already replaced and calibrated and p0505 Idle Control System Malfunction. no i havent tryed bleeeding the lines i didnt think that would be it but its worth a try how do i bleed them?

RonJ

The TPS code may be causing code P0505. Have you checked voltage to and from the TPS at closed and wide open throttle?

Air in the cooling system can cause a hunting idle, as can a disconnected vacuum hose or an intake air leak from the TB or IM gasket.

P0505 can also be thrown by a bad ECT sensor (2-wire plug under the distributor), so check that as well.

tps voltage is good... air bubbles not the problem..... could it be spark plug wires?
