My friend has a 2002 Jeep Grand Cherokee Overland. She called me saying her Jeep would stall when coming to a stop. She had some friends take it to Autozone who found several codes. P0158, P0320, P0161, P0340, and P1391. I looked up the codes to find out what they are, but my questions is, why would they all just light up like that? Do all these sensors need to be replaced or is it possible the computer is bad? She mentioned having problems with the gauges, where they would randomly stop working and then start again, and a similar problem with the wipers doing the same thing. She lives in Florida and I'm in Georgia so that makes things a bit more difficult for me to help diagnose. Any advice would be greatly appreciated.

Thanks, Doug
