Ignition coil codes
I hope someone can please help. I cant get my truck through inspection because of MIL on. Codes for ignition coils 4 & 5. I changed coil packs, spark plugs, wires, MAP sensor and light wont go off. Not sure what to do next & my last temp tag just expired. I would really appreciate any input.
Make sure the connectors are making good contact. The female side likes to expand, and then they don't connect well. Could also rent some noid lights for your local big-chain auto parts store, and verify the PCM is actually firing those coils.....
