How do you know if your TPS is bad?
Well, I went to test the voltage on my TPS. It put out perfect voltage for closed throttle, but WOT is a different story. One reading was off the scale. The other was WAY too high. I guess that could explain some of my problems. Still, how do I know if my TPS Is bad or not? Would I be getting no voltage at all if it was bad?

Measure both the low and high sides from closed all the way to open.
Look for a smooth transistion without any drop offs.
You should have at least given us the 4 end points readings!

First off I do have a PFC. No commander though.
Second off - I tried adjusting it. I can get the low sides to get close to spec. The bottom wire is at .01 and the top is at 1.4. Thats as close as I can get it. If I move the thottle plate the bottom one will go all the way to 8. The top one goes off my scale. It does make a smooth transition, but by about half throttle its already at 4 on both of them.
