We've replaced EVERYTHING underneath the timing cover, the spark plugs, spark plug wires, coil, computer, new radiator, new TPS, New Crankshaft/Camshaft sensor... all recently replaced yet its still having this weird issue...it will run perfectly at random and not even run at all or backfire/misfire run rough, my whole family has been mechanics for years and we can't figure it out.. Anyone have any ideas?
