    Hello -
    Any time the engine is cold or not warmed up there is a noticeable decrease in power... there is no "check engine" light ... I scanned for codes using two different scanners none were present... truck is a 2007 AT V6 with 130,000 miles... any help would be appreciated.
    even when its fully warmed up it still feels like its not 100%
    Thanks

    Try cleaning the throttle body and mass air flow sensor and change your air filter. Easy way to gain power back there. Check your plugs too. That's all I can think of if there aren't any codes.

    After you've done that and still feel a little sluggish I say try doing a fuel injection cleaning or at least try Amsoil P.I.
