Does TPS read 0%?

I had issues with idling that ended up being a mechanical issue. The first issue was that my TCS module was hanging up. Fixed.that then found a faulty TPS that I'd replaced. I had to put seemingly excessive force to the TPS to push the new cheap **** aftermarket sensor onto the TB shaft that the whole assembly had pressure on it from the right side (sensor side) and was causing the blade to hang up. I lightly tapped on the left hand side of the linkage with a hammer and it's all good now.
Good luck.
Beau
