I changed out number four coil pack, changed all the spark plugs and cleared the code. It continued to miss fire and the light came back on, I took number three and number four coil packs and switched them out, cleared the code and still getting a miss fire on number four cylinder. I notice that number four fuel injector had a little corrosion. So I replaced the injector and the wire connectors still getting a miss fire. I am now thinking the plug and the coil pack may not be getting any fire. How do I check it and. What is your opinion, I am baffled.
have the same problem?
