I have a very unusual probel w/my 97 grand cherokee ltd (6 cyl). seems it has stumped the chrysler/jeep dealer I finally brought it for service. HAd another mech try to diagnose and fix and after an induction coil, ign coil, idle air valve and crank sensor replacement, seems the problem still exists. The problem:Car will stall when at idle and difficult if not impossible to restart. leave it alone for a few minutes it will restart. engine could be cold or at operating temp. while driving it has also stalled, but most times will "restart" enroute. Chrysler has had the car for several weeks now and they are still scratching their heads. Thier best best guess is that ther was carbon build up at the air idle valve. They cleaned it, I drove it for a day and then it starts to stall again. I had a multiple missfire code when it initially happened and you could tell that when trying to restart it was miss firing. Recently the check engine light came on and error code 21 (oxygen sensor voltage?) flashed. was on for three days , when I brought it back to Chyrsler, the check engine light no longer lit, don't know if the code was still there? Anyway...anybody got any ideas? Chrysler sure doesn't!
