this started as a random misfore and turned into this p0302. i tried one by one eliminating things it could be. changed to factory delco plugs didnt help. next changed plug wires. after that i changed out coilpack. i also have new 02 sensors. any tips or ideas on where to go from here before i go to a dealer to rape me on a diagnostic? id appretiate it
sorry title shoulda been p0302. also how would a cat cause a specific cyl to misfire? i have a new cat but dont get how that could even be a posability?
