Is this a throttle body injection? If yes look at injectors while running shine flash light on fuel stream. May have leaking injector spray should be fine mist 360 degree patteren. If you see driping or streaming then inj need cleaning or replaced.

If you pull off the numer 3 and number 5 plug wires while running it doesnt change anything even if you pull them both at the same time it runs the same. Could it be the heard gasket blown between two cyl? The injectors seem to be ok.
