    as above
    after replacing filters and seals to all injectors. the car is miss firing and smelling of unburnt fuel from the exhaust.
    wires to the injectors seem fine.
    i did not disconnect any of the fuel lines, just unboltet the fuel rail to get to the clips and injectors.

    any ideas

    thanks mark

    Sounds like when I changed mine and put the wrong seals to seal the joint on the injector

    did a quick test with injectors on fuel rail and not fitted into manifold, turned engin over, 1 injector spraying all the time!!!

    looks like the injector is fooked, swaped it over to other lead incase it was the wireing but got the same result.

    must have damaged it some how,

    cheers mark
