Have you checked for a possible vacuum leak? For the TPS, you should check the voltage at the plug, with key on, engine off, by back stabbing the harness with a volt meter. The volts should be close to 1 volt at idle position, contine to manually move throttle body to fully open position while watching your volt guage. It should be smoothly climbing the more you open the throttle and should read near 5 volts at fully open. If I recall, it is the top and bottom wires that you want to check. Been awile, search the net if you don't get a signal.
