Ok posted this in electric but think wrong place i bought 05 liberty renegade for wife it had this problem when i got it when you start it has a miss when you get above 2000rpm starts cutting out. No fire or injector on number 5 not getting ground pulse from pcu getting codes p2302 insufficent ionization and miss fire on number 5 thought might be crank or cam sensor butt why only come up on one cylinder cats are good o2 test good replace 1 good compression average 180psi traced wires all good so far just wanted to know if you think might be bad pcu.
