1989 idle problem when hot
I have an 89 5.0 stock. Car runs good cold, however once it heats up it will sputter/die when idle, such as a red light. It's driving me crazy and I keep throwing money I don't have at it. This is what I've done so far and still continues to give idle problems hot
New: plugs, cap, rotor, coil, tfi, coolant temp sensor.
I cleaned and checked pcv, salt n pepper connections, iac (oem original).
I'm reading codes for o2's and grounds look good, could that really cause bad hot idle? Any help here would be greatly appreciated before I go insane.
