1. Check Idle Air Control (IAC) Solenoid Resistance Turn ignition off. Disconnect IAC wiring harness connector. Connect DVOM positive lead to VPWR (White/Red wire) terminal of IAC solenoid wiring harness connector. Connect DVOM negative lead to IAC terminal. If resistance is 6-13 ohms, go to next step. If resistance is not 6-13 ohms, replace IAC valve assembly.
2. Check IAC Solenoid Internal Short To Case Turn ignition off. Measure resistance between each wiring harness connector terminal and IAC housing. If either resistance is less than 10,000 ohms, replace IAC solenoid assembly. If each resistance is 10,000 ohms or more, IAC solenoid is okay.
Remove and use carb cleaner and clean it
check for a vacuum leaks
