tps is easy to fix, get the new one and then grab an ohm meter and stick the red lead into the middle wire on the tps and the black to a good ground....if its at .5 volts closed and 1.0 at WOT leave it, if not make it by taking the screws out a little and moving it around...make sure the little arm in the TB is lined up with the tps....i messed with mine up at SS for about 20 min after I took it off and repositioned it and thought I had it in there and it wasn't...
