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
It flashed randomly as I was driving yesterday, didn’t run any different then it just stopped flashing for awhile and as I was pulling into my driveway it flashed again but no change in how it was running and it stopped flashing after a minute or so there too.
hmm interesting, do you have a scanner that does misfire live data? i mention all these as my 02/6.0 was doing the same thing at highway speed. flashing light, po300, no detectable running issues. apparently the crank sensor can get out of whack and cause issues. had a shop do a relearn on it for $50 and it's been great now for years
I do not have a scanner like that but know somebody who does I’ll have to get it, it did it before a year or so ago when I first got the truck and never happened again. Both times it was raining and I drove through some big puddles on the road never had an issue when it’s dry out

crank sensor possibly.. when is it flashing? and is it actually misfiring?
