I have a 2002 Jeep Grand Cherokee with 207,000 miles that has recently begun stalling while driving. Typically stalls at rest or when coming to a stop, and for a time it would re-start without issue. More recently it won’t start readily after stalling, but will eventually start with enough key-turning persistsence. The check engine light comes on only after stalling and not restarting (but was not on previously), and often shuts off after a few miles of smooth running. I took it to my local mechanic who ran the computer codes and reported a malfunctioning cam shaft position sensor (i question if this was the casuality of other problem), which they thought was the source of the stalling, but after replacement it is stalling more than ever. It seems like the local mechanic group won’t diagnose anything in this high mile Jeep without a computer code and I am reluctant to bring it back.
Any thoughts on the cause of the stalling / starting issue? I may be way off but was concerned about a clogged fuel filter or fuel injection problems. These ideas were not entertained by the local mechanic group… All feedback appreciated!
