Freind's Jeep - Problems.

[DiamantMeister]

Hey guys, I wanted to see if any of you guys could help me out with this:

A freind of mine has 00 Jeep Wrangler, 5spd. 4.0l, and she told me that she is having problems with it...

Description of the problem:

She'll be driving down the road and it will just smooth out die. She told me that when she fires it back up, it will not stay idle. I suggested to her that she get it started and hold the RPMs at 1 Grand to try and reteach the computer what Idle was. I, being the dumb person I am with cars, thought that maybe the battery or alternator is going out thus reseting the computer as she is driving down the road.

This Jeep might as well be a caddilac- she does no offroading or anything harsh in it. She does like 40 under the freekin' speed limit, and as far as I know, she keeps it well maintained on the oil schedule. Any tips?

Thanks!

Battery is dead and won't hold the charge probably. Mine is like that right now. Once I get it jumpstarted I have to keep my foot on the gas for a few minutes to keep it running. Otherwise it won't stay at an idle and just sputters and dies. I'd have the battery checked first and then go from there. I know mine is the stock one that came with it in 2001 so it's definetly due to be replaced.

coil perhaps? when it warms up, the windings can open up and cause trouble
