    bad rs2 injector

    my car was not running fine and i have found out that one of the rs2 injectors was faulty (if i unplugged nothing changed so this one must be faulty)
    i can try to clean the injectors but i have another set of injectors of a audi a4 2.8L 30v
    could i swap these injectors or is this not a good idea?
    the part number is: 078 133 551 L

        I would first check there isn't an issue with the wiring to the injector in question. Also. Change injectors around and see if the fault moves with the injector...

          Did you swap the injector to check the problem moves, and that there is spark at that cylinder.

          Unplugging the injector narrows the problem to that cylinder, but does not prove injector, plug, coil, pos, ignition wiring, injector wiring, injector plug etc.

              Very true! Also do a compression test...can be head gasket.
