Working on a factory 2004 Isuzu asender with the 5.3, motor has a miss so I checked and cleaned all injectors, changed the coil packs and now still have a miss in the number 2 cylinder. Later proceed to change PCM and and chased wire, still have a miss. Checked spark with new spark plug and it's a no. What in the world am I missing? Could it possibly be the crank sensor? If that were true wouldn't it be erratic?
