the tps is the one right on top w/ the orange and green wires coming out of it...kinda round shaped
pierce the wire w/ a safety pin (green i think ,i forgot green or orange one , and all that will happen if it's wrong is the read will be way off and you'll know it's the wrong wire)
anyway....w/ the key on, but the engine still off , read the multi meter (touch the safety pin w/ the red lead and touch a ground spot w/ the black)
if it's somewhere around .960-.990 leave it alone
if it's higher or lower loosen the 2 screws holding it, and turn it then tighten it where it reads .960-.990
you may need to remove it completely and open the holes up w/ a drill, i have had to on everyone i've done,so plan on it
if you need to ttrmove it...nothing will pop out or fall apart so no worry
good luck....bob
