no but i changed the throttle body and it made a huge difference. now it just is kinda high at idle, but i think the idle air control valve is bad looks like it might of been bent some. Got to figure out how to hook up the OBD2 Port i believe the orange is the ign hot wire, there are two black weirs i guess there ground? matter where they ground to truck or battery? and the purple wire is the wire for the OBD2 wire coming out of the harness. I just cant get the OBD2 code reader to read anything. ign on and both black wires tied together and hooked to good ground.
