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

so when i unplug the idle air valve it should just die like i cut the switch off? and does anyone know how the set the star screw, under the little cap, that has something to do with the idle air valve?? i thought i had everything kinda close but sense i read all that now idk. im glad theres someone smart in this world to help me!!!!!
will a 95 tps plug up to the 88 wiring harness? cause right now it has a explorer tps straight wired to a plug then plugged in the harness. when i bought a water pump for it i had to get one for a 90-91. is there any way to tell if it is a 95 motor? dang this sucks. now i dont know what the hell kind of motor it is or what all is done to this car. a explorer intake and throttle body looks the same. i was planning on getting a new wiring harness for it anyways and had one found for a 98 but now idk what ive got
lol yea it runs great. it runs as good as my s10 i had. and it holds oil just fine lol. now im thinking more about pulling this motor and all the elctronic stuff and putting a 4 barrell on it. how can it be running with that thing just hanging there??
