    I have a 1997 456 GTA with a recuring injection/electrical problem in which one of the injector banks shuts off randomly. Anyone have this problem or any recomendations?

    I would suggest taking a look at the wire connections for the fuel timing. They should be located at the rear of one of the intake cams. If they get loose it will mess up it fuel supply and fuel timing. The other thing is are you getting any engine lights?

    Perhaps try resetting the ECU. I had similar problem on mine (engine intakes were pulling in too much air on one side) - but resetting it did the trick.

    No engine lights, only perfomance problem.
    Thanks!

    Excuse my ignorance Gorda456GTA. Could you please advice the performance problem encountered? Loss of power?
