[DML] Re: Recent High Idle Problem

["Sean" <sweitzel@xxxxxxxxxx>]

I recently observed on the car I am restoring that if the idle speed
thermistor comes unplugged or fails open, this will cause the car to
idle at 2000rpm no matter what you do. Get a digital multimeter and
gain access to the idle ECU under the parcel tray behind the driver's
seat. Unplug the 2nd white connector and measure between pins 9 and
11. If it is an open circuit, your idle speed thermistor is either bad
or the  connector came unplugged or the wire failed. 

In my case, one of the two pins on the plug was pushed up into the
housing and not making contact when I reassembled the top half of the
motor. I was able to cram my hand under the intake enough to unplug
it, reseat the wire and plug it back in. It took about 40 minutes of
feeling around while sitting on top of the motor. (louvers and engine
lid were off at the time)
