heres the deal....on my 64 mm rc t/b...i made a horrible mistake a while ago and unscrewed the tps off of the back and i played with it to get it to idle ok but now im having problems again. I was just curious do i just check voltage of the tps?? How do I get it set right on the t/b so my idle wont keep messing up...my throttle sticks after I let of the gas..my vafc reads like anywhere from .7 throttle to 2.0 % after my foot is off....any help is appreciated..

 

Ok this is how you fix the sticky throttle body. First take the throttle body off the car. Then under the cable hanger you will see a screw and a bolt on the underside of the throttle body (right side). Open and close the throttle body and you will see how the bolt stops the plate at a certain point. The reason yours sticks is becuase the plate is closing too much. You need a little open space. Loosen the bolt and turn the screw slightly to open the plate more. I would say 1/8 to 1/4 of a turn is enough. Then thighten the bolt to hold the screw in place. Put the t/b back and you car will be fine. If your check engine light comes on then you opened the plate too much.

To fix the voltage you will need a voltage meter, but I'm not sure how to do this.
