The surging at idle is actually a sigh the throttle switch is working.
If it wasn't closed when the throttle is closed the surging wouldn't be
there. Now, why is it surging?>>

If the throttle shaft is worn it will cause the idle to hunt or seek.

If the initial throttle stop gap isn't correct, it will cause the idle
to hunt or seek.

If the switch is set with the wrong gap at the stop it will cause the
idle to hunt or seek.

If the switch isn't set up properly it will effect the idle the same
way, which will cause one to think the idle stabilizer is acting up.

If the switch is burnt out it will make one think that the idle
stabilizer is bad.

This is why one investigating any idling problem should start at the TPS
first.
