Sometimes, quits at stop light/sign and I have to turn key off and will restart. Occasionally the accelerated will just increase RPM from idle to 1500 while stopped. CEL never comes on in any situation. I am seeing there doesn't appear to be a solution after all the posts I am reading.
I have the exact same problem.
2007 Commander with Hemi
Babied, always maintained correctly. Everything has been by the book. I have done all the oil changes, it has never seen anything but 5w-20 full synthetic.
-Started stalling randomly at stop lights. Maybe once a week.
-Changed plugs, which were OEM, to new OEM plugs. Stalling seemed to get better
-6 months later stalling is back. It stalled on the Interstate on my wife and she nearly crashed.
-Has stalled out at stop lights like 20 times overall. Am friends with Jeep dealer mechanic. He wants me to change plugs (again) because apparently there are two different OEM plugs of the same part number. One has a black top, the other has a silver top. I am not sure which ones I have but will update when I pull one this weeked. I believe (there is a technical service bulletin) that the black tops are the correct OEM plugs.......
If anyone gets a definitive solution to this I would be greatly appreciative. I am out of warranty and cannot afford to get swindled at the dealership.
