P0302 Jeep - CYLINDER 2 MISFIRE

Question

GOOD MORNING,
I HAVE A 2012 JEEP GRAND CHEROKEE, THE ENGINE LIGHT IS ON AND IN CHECKING WITH MY LOCAL MECHANIC WHO TOLD ME THAT IT WAS A PO302 CYLINDER MISFIRE WHICH HE COULDN'T WORK ON. I WAS ADVISED TO GO TO CHRYSLER DEALERSHIP WHICH I HAVE AN APPOINTMENT WITH. I HAVE 40,000 MILES ON MY CAR, IS THIS SOMETHING WHICH WILL BE COVERED UNDER WARRANTY OR IS THIS GOING TO BE A COSTLY REPAIR?
THANK YOU,
ERIC

Answer 1

It should be covered under warranty, might be a bad spark plug or a bad coil or maybe a clogg or bad fuel injector 

 

 

 

Possible causes

- Faulty spark plug 2

- Clogged or faulty fuel injector 2

- Faulty ignition coil 2

- Fuel injector 2 harness is open or shorted

- Fuel injector 2 circuit poor electrical connection

- Ignition coil 2 harness is open or shorted

- Ignition coil 2 circuit poor electrical connection

- Insufficient cylinder 2 compression

- Incorrect fuel pressure

- Intake air leak
