So I got my tranny serviced, my diff. serviced, (had my plugs changed in Feb.) and my throttle body serviced. They told me the t.b. had some sort of cable that was loose. (forgive me, for I am mechanically challenged, lol) Anyway, they performed the service and apparently "fixed" whatever was wrong with this cable they spoke of....and my truck is NOTICEABLY peppier. And I haven't even gotten the flashpaq yet. It feels like a different truck...seriously. Maybe you guys can tell me why this is as well: My gas pedal is higher up away from the floor...like there is more distance b/w the pedal and the floor. ????
