FUNCTION
Idle fuel shut-off solenoids act as check valves. When the ignition switch is turned OFF, the solenoids shut off the fuel at the idle port to prevent dieseling or after-run.
TROUBLESHOOTING
If the idle shuft-off solenoid is not functioning properly, the driver may experience
- Dieseling or after-run
- Shut-off valve malfunction produces the same characteristics as a plugged carburetor idle jet (rough idle)
TESTING
To test the valve: disconnect and reconnect the single pin connections individually with the ignition switched on. The noise caused by the valve opening will be audible. If you don't hear the click, your solenoid is bad
