The Jeep starts and runs for a few minutes and then it starts running rough but it does not stall. Check engine light does not come on when you start it. How do I check the bulb?
Sounds like a few issues. The check engine light should come on when you turn the key to "ON" without attempting to start it. If it doesn't, the bulb could be bad and that would mean removing the instrument cluster to change the bulb.
The rough idle issue could be a partially stuck open EGR valve. Remove the valve and clean it good. While you have it out make sure the diaphragm moves freely. Replace the valve if you can't clean it or if it doesn't move.
Go to your local auto parts store and ask them to read the codes (most store provide this as a free service).

warped heads will cause this...if it over heated badly thats going to be the problem

fuel pressure seems a bit high...could be a bad regulator. can't remember if yours is on top of the sending unit (on tank) or on the fuel rail though. Do more testing there.

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.
