First off, new to this site and I have searched before posting. Anyway, I have a stock '77 and I notice the tps is set to the WOT side constantly. When I attempt to adjust it to the idle side, the car begins to run very poorly and it will eventually die and not start again. As soon as it is set back to the WOT position, it runs fine. Do I have a bad tps or should I look elsewhere? BTW, the car has all new tune up and fuel system components and I have cleaned all the wiring connectors.
