Engine Performance problem
1989 Chevy Celebrity 6 cyl Front Wheel Drive Automatic 256000 miles
This is a 2.8l Multi-Port Fuel Injected vehicle. My engine idle has recently increased to ~1000 RPM and will not decrease after the engine has warmed up. The Throttle position sensor voltage is 0.7V and the Idle Air Control resistance is 50 ohms on each coil. I have no Fault codes. Where else should I be looking for the cause of the high engine idle?
have the same problem?
