New idle speed motor (VDO). Throttle position switch adjusted to closed at idle, closed at wide open throttle. No false air leaks detected and when it came in, the O2 sensor was disconnected. Cleaned up the O2 harness' and made sure the throttle sensor was ok...the throttle sensor needed a little tweaking to close properly and we figured that was the problem, but once the idle speed motor is connected it starts it's little surge dance once again. Coolant sensor was connected and wiring harness appears intact. Customer had to leave immediately for the airport so we bumped up the bypass screw (base idle) and disconnected the IAC as temporary measure. So...no time to go into further diagnositics...any ideas of where to look next? I see something in my 'runs funny book' about an updated harness for the air flow meter, but I think those are for the air cooled transporters. Thanks group!
