Default '91' 940 turbo won't idle
Should the Idle control motor vibrate (or hum) with the ignition on, engine off. Mine does not, I think it might be bad.

Thanks,
Bobby

Thanks, I think I will replace it than. Also clean every thing else (intake) and go from there. Any other ideals are welcome.

Thanks jonesg

Before buying a new one check for voltage at the plug, if no voltage check the throttle idle switch.
It should click as throttle is opened and closed.
I believe that controls the idle motor.

Yes voltage at the plug. So new idle motor.

Thank You!
