car idle surges and stalls
I have a 93 Z24. the idle goes from about 800 up to 1200 after the engine warms up. then when driving, stalls when i come to a stop. need help fast. i was thinking IAC or TPS. any other ideas???
sounds like your IAC-Idle Control Valve or TPS-throttle position scencor is bad,or it could have a vac leak.
It is your IAC... The up and down idle is the primary symptom of a bad IAC..... A Bad TPS would not let the car idle at all.
thanks mike. appreciate the help.
