Mixture Control Solenoid
Disconnect mixture control solenoid harness connector. Check resistance between solenoid terminals. Normal resistance is 20-32 ohms. Check for unwanted shorts to ground between solenoid connector terminals and solenoid body. Resistance to ground should be infinite. If resistance is less than 10 ohms or if solenoid has continuity to ground, replace solenoid.
