What could cause multiple TPS's to go bad? (S4 n/a)

I'm pretty sure there's no vacuum leaks, I've replaced all the intake gaskets, injectors cleaned with new grommets and o-rings and replaced a bunch of vacuum lines after the rat's nest removal. I think the problem is purely electronic.


Also, I realize the first posts are kind of confusing, so the main questions is, is there anything that can cause a TPS to be out of spec if the TPS itself isn't bad? I'm pretty sure this TPS I have now is good, but I can't get it below 2k ohms closed and it always goes to 8k at WOT. One of the other TPS's I had that was 'bad' tested good at a dealership. I'm pretty stumped over here.
