on a 86 mustang 2.3 non turbo dose the TPS sensor have to be adjusted? i did some rewireing of the stereo in my car and after i rehooked up the neg bat cable my car went straight to fast idle. before when it did that it was the TPS but i replased it and it hasnt fixe the problem when i unplug the TPS it idles fine but when i plug it back up it revs high. if i leave it pluged up step on the gas it will reve high for abut 15 sec before it will return to regular speed. it also sticks during driving
