    Reduced Engine Power

    I took off the tb,when I put it back on the truck sayed REDUCED ENGINE POWER, and the throttle does nothing. I unhooked the battery and still nothing. what else could it be?

    LOL!!!! Carlos Mencia is ridiculous funny! When you said that it took you all day to find the problem, this was the first thing that came to mind...

    on the side of the tb the black box is held on by rivets. I cut them off and pulled it apart. theres 2 prongs and 1 was not conected all the way.but i keep getting the reduced engine power after that.

    i think i ended up leaving my battery cable off for the night or something .i couldnt believe just pulling the tb off would do this .hope its all set.
