[DML] Re: High Idle only when warm

["Dave Swingle" <swingle_dmc@xxxxxxxxxxx>]

If the thermistor that is connected to the idle ECU fails (open) the 
car will idle at about 2500-3000 rpm. 

A quick check is to unplug ONE of the idle ECU connectors - the one 
that's toward the passenger side of the car. You'll have the same 
effect, it will open the idle motor wide open. If everything is 
working.
