GM 5.3 misfire problem
GM 5.3 misfire problem 2010 Chevy Silverado
139K. Was driving down the highway at 60mph. Check engine light started flashing. Pulled over and it was ticking. Shut it off. Towed back home. Comp testing showed 160-180 for all of the cylinders. Can confirm that the valves move with the covers off. Codes are for misfire #4 and low oil pressure. Anyone have any ideas?
