So if I read right, you used a noid and determined all the injectors were firing properly along with swapping both injectors, spark plugs, and spark plug wires to no avail along with checking compression?

Only thing that would make sense to me is your cam went flat on those cylinders at this point. Not trying to scare you, just a thought....easy to see lobes through valve cover removal.
