01 Sahara 4.0 Help! Stalling!!

Bought 01 4.0 Automatic with about 120K miles on it. The dealer said if anything happened to bring it back and he would fix it before I bought it. Well, it started stalling while driving and it was very hard to get back started. Usually had to wait five minutes or so.

It showed a code P0320 (crankshaft position sensor) so the dealer replaced that, the camshaft position sensor AND the computer. He told me the fuel pressure tested fine. Brought it back to me and it drove fine for a day. Today it started stalling again. I did the key thing and it still showed the same code. I checked the battery connectors and the positive was a little dirty and seemed a little loose. I took it off and cleaned it really good and left it unhooked for about 15 minutes to clear the code. Put it back together and started up just fine.

Any ideas of what else could be going wrong with it since they have replaced all those parts? I'm taking it back to them tomorrow.

It could just be you need a new battery. If the battery is almost dead, the engine will run rough and stall. The alternator won't be enough to keep it running smoothly. Have them check the battery first. Good luck.

I thought about that. The battery (Wal-Mart brand) was put in in 08. I'll get it tested tomorrow.

I was having issues with my jeep stalling and the gages bouncing eraticlly. I had it checked out and was told it was the voltage regulator, of course that is build in to the altinator. However the new one did the same thing, so I got my money back. Ended up replacing the battery with a Wal-mart one, it fixed it for about 6 months, then it started acting up again. This last time I replaced it with a good quality battery and I haven't had an issued, that was two years ago.
