    2004 300X loosing power over 3k rpm.

    Cylinders 2,4 and 6 seem to be getting lean over 3K RPM. Spark plugs are very light on these cylinders only. Any ideas? ECU?

    Thanks,

    Thanks,
    Could be ECU. When was the last time the injectors were cleaned have you moved the injectors around to see if plug color follows the injector.
