Idle surge when cold
#11
The truck runs really well except for the idle thing. It sat 3 weeks in my driveway and started right up without any problem. It is unlikely it will need to be reprogrammed. When I cleaned the IACV on my truck I noticed the tip of the plunger has scuff marks from rubbing on the plenum. I did a little research and found this:

So I'll try the NAPA replacement. I remember reading a post on this board the 4.0L Jeep one doesn't work, unless someone is using one right now and can chime in to confirm it works.

Definitly not being a nay-sayer, but don't bank on that too much. Unless the replacement part's plunger is in the exact( or darn close) spot as the old, it will not function correct.
When I replaced mine, the dealer said it should adjust itself after a bunch of drive cycles. Never did. They didn't have to reprogram anything, what they do is hook it up to theit testbook and clear all the adaptive memory's. Of course for the bargin price of a $100 and change for 15 min's of work. Has run/idled like a champ ever since.

So I was stalking on the thread and I realized I have the opposite problem haha. She starts up fine, but when it is cold I realize she idles from 750-1000. And you can hear the diff. Also when I press on the accelerator it sounds like she lost power for a second than regains it. I'll check this afternoon after school also to be sure. But would that mean I should clean my IACV?
