Vortec 5300 5.3L V8
So I got a 2013 Chevy Silverado 1500 LT 4WD, and I have a misfire on cylinder 1, I replaced the spark plugs, every gasket known to man, the coil packs, the lifters, the coil pack wires, and the fuel injectors but no fix, I then gave up and took it to the Chevy shop and they said they don’t know...
