Ok sorry for the delay. I bought an new tps however it was the wrong one (manual trans one). So I ordered the Motorcraft one and got it yesterday. This one doesn't seem to have a spring to make it return to its original position. Is it supposed to? Maybe I have a defective one because now the car shifts like the sensor isn't working. I can't track down another one to compare it to. With it in though it seems to be driving/idling a lot better besides the rough shifting. I also bought the correct pcv line so that is installed correctly now.
The alternator is working correctly and putting out about 14 volts.
