Has anyone ever had a P0351 before? I have a 97 Jeep Grand Cherokee with 178K with a 4.0 engine. I get this code as a pending code and not a trouble code. The truck starts to misfire and then just stalls out. It stalls sometimes in a few miles and also I have gone 20+ miles before it gives up. It starts right up and sometimes gives me grief right after and sometimes not. I had two other guys tell me the same thing and I thought I could help them. They have replaced the igntion coil (I did too), and one even replaced the crank and camshaft position sensors. I unplugged the sensors and the engine does as the book explains: The engine remembers last firing point and keeps running until shut off. The check light comes on and everything, and nothing changes. One guy changed his battery wires and still had no change. This seems to me to be a common deal. Its like the coil is being shut off by something ( I think). My friend said it might be the ASD (automatic shut down) relay, and it made sense, but nothing changed. Does anyone know anything about this condition? t2erns???? Anything will help! Thank you very much!
