My jeep had a code of p0305. It has 135,000 miles, so I changed the plugs and ignition coil. I reset ecu and the code came back. I switched the plug wires to see if I received an error on a different cylinder and got p0300. I am trying to figure out if cleaning the EGR(my next task) will correct error? I don't have any exhaust leaks, intake leaks.
