Hi All,

I have a problem with this Vanagon Idling too high(app.12
too 1500) intermittenly. Throttle switches were bad so we
replaced them. Idle controll motor and controll unit have
been replaced with known good unit. The ECU has also been
replaced with good unit with no change.

When the green wire with yellow connector is unpluged (for
testing the Idle stabl..) Rpm Goes to 2500.

When the Idle Stabl.. is unpluged the idle is normal until
the engine is restarted.

Any Help is appreciated>

Thanks
