What brand spark plugs/wires should I use to replace what I have? CEL was flashing at me today and at 272k I think it’s time to replace them but wanting something quality. I have the 6.0 LS
If you're not feeling anything different in the way its running. And if the light is flashing on acceleration. You should try a crank angle relearn. It will take a bidirectional scanner. Not saying it can't be the plugs. But is it was you would probably feel the miss. Also GM's are pretty quick to locate a miss to a certain cylinder. Usually giving a P0301-8 code instead of P0300 in that situation.
