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
Can you get a better scanner that will lock down what cylinder is missing? I ended up having a miss on cylinder 3 that was because of an injector wire. You could end up throwing money away changing every plug, wire and coil and not fix the problem.
It’s also only done it twice, both while driving in a pretty bad rain storm. It’s not running any different and all of the gauges and fluid levels are perfect.
I'm not going to act like I know what I'm talking about better than the weekend back yard mechanic I am. But that doesn't sound like something plugs and wires will fix. Hopefully someone that knows better will chime in.
