Jeep Cherokee Crank sensor problems
I have a 2000 Jeep Cherokee with 185,000 miles on it. I keep getting the some 2 codes, P0340 & P1391. I have changed the Crank sensor and the Cam Sensor also put a new battery and spark plugs in it. But when your driving it it misses about every 15 to 20 seconds. I’m not sure what else it could be, any help would be appreciated !

What brand crank and cam sensor? Anything but Mopar is questionable as aftermarket can be bad right out of the box. It can, and does happen. Also, trouble codes for a particular sensor dont always mean the sensor itself is bad, so check the wiring for any loose or corroded connections.

Could be bad wiring, bad ignition coil, also check for any wear, play, or damage to dizzy

My experience when you get both of those specific codes together is that it is usually the "camshaft position sensor" circuit that is the cause.
I would concentrate on that circuit.
