New plugs, wires, cap, rotor, # 4 is fireing, I have held a plug to the cover when running, plenty of fire, no change in motor when running and I unplug# 4 injector, I replaced #4 injector 100.00, still no change, what next, use car for scud missle test? Is the computer possibly bad? Can the crank pos sensor cause this?
