Check that the idle switch on the throttle body is operational. With engine
turned off, you should hear an audible 'click' when moving the throttle
lever to and from the idle position. If no, you may need to clean the
throttle body and/or switch, the switch must close for the idle stabilizer
valve to operate. Other possibilities are a defective idle stabilizer
control unit (behind the plastic cover at the right rear), or a defective or
dirty idle stabilizer valve. Least likely is a broken wire, but I've seen
all of these causes in different vans.
