bought mustang from guy and turns out that the plenum and throtle body on it is from a 5.0 explorer. it is the plenum with the curved neck for the throtle body. well i was wondering if this could make it jumpy at low idle and cause it to idle high. i have the screw in the throtle all the way out and the star screw (that has something to do with the idle air valve) is barely turned out. does this plenum give it more horse power and could it be why its so touchy and hard to set idle?

check your timing, could explain the idle, yes the explorer intake is better than the stock 5.0 intake, its an improved version of the gt40, as far as power increase, I wouldn't think it'd be much, but it is a better intake, start looking at other things for the idle
