hi there, sounds like a bad fuel pressure regulator. a bad regulator will cause it to misfire and idle rough. also does it run good at higher rpm if it does i would be 80% sure that would be your problem

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.

Please be fast about checking your fuel pump. It is not giving enough fuel pressure.
