I have a 2015 Silverado 5.3 4x4, automatic, 23,xxx miles. Today when I was leaving work, I kind of got on throttle, a few seconds later my check engine light started flashing and my traction control light (I think thats what it is) came on. Went back to work, hooked code reader, Cylinder 7 Misfire. Cleared it, headed home, lights both came back on at around 1500rpms. Got home switched plug wires for grins, cleared code, same thing happened. Anyone have any ideas, on my 2015 Silverado with 23,635 miles???

What the actual spark plug itself.

If not that, swap coils, then maybe open the valve cover to check for a broken spring. Worst case is that it's a lifter or cam problem.

Just bought the truck a couple weeks ago, so I'm not to familiar with the mechanics of it yet. Gonna try swapping coils, check plug and do s compression test on the cylinder tomorrow. Just didn't think it would be a cool or plug being so new, but I guess anything is possible.
