JEEP GRAND CHEROKEE DEALER PROBLEM

2004 Jeep Grand Cherokee • 90,000 miles

I have a 4.0 liter that I have replaced the IAC on several times. Somewhere I read that the tip of the plunger measured from the mounting base s/b no more than. Also how can I tell where the plunger is in tis cycle? I want to try one more time before taking to the dealer. Right now it is idling at 1100 to 1600 and I can't drive it. Someone told me that there may be a way to get the engine to adjust to the new plunger by turning the key on and off several times?

The only way to see where it is, is with the use of a scan tool. It can be driven in and out to see if it functions.

Did you clean the passage way very well? Carbon is your worst enemy in throttle bodies.
