Jeep: '97 XJ, 4.0, AW-4, NP-231. Tune-up parts are all fresh (<5K miles).
Symptoms: After driving for 10-15 minutes, jeeps starts to run rough and will die, it can be restarted once or twice, but then it is dead for at least an hour. Eventually it can be restarted but it will still only run for a short time. The other weird part is that while driving the speedometer will randomly peg, then come back down. This part is really bothering me.
Codes: these are all pending but I got P0351, P0300, P0302, P0304, P0306.
Thinking P0351 is key, as the rest are just misfire codes, and I didn't need the computer to tell me that there was a misfire...
P0351 is Ignition Coil A Primary/Secondary Circuit, but some searching tells me that few people actually had a problem with the ignition coil.
So far:
-Fuel pressure is good (48 PSI)
-CKP is good (replaced w/my trail spare that was removed from a perfectly good part-out, same issue)
-Swapped ASD and fuel pump relays, no change
On my way to pick up a new Camshaft position sensor and Ignition coil now, but in the mean time does anyone else have suggestions? That speedometer issue is really bothering me and I'm worried it suggests more than just a sensor.
Thanks.
