I remember back in the 5.0 days you could adjust your TPS for better throttle response. Can you do this on the new 4.6? Has anyone done it? What did you set the voltage at?

I tried mine and the voltage started out at 0.86v. I moved it as far as i could and it went to 0.92v. Ive heard the best is 0.97v to 0.99v. The older ones used to have one screw hole that was elongated so that you could adjust it, mine didnt the 2 holes were alittle bigger than the screws and could only be adjusted so far.

What up with that?

They changed it a few years back so that you cant adjust them. I believe the spec is .98 volts at closed throttle, 4.5 - 5 volts at WOT. I used a Dremel tool to make the holes bigger. They have metal sleeves in them, and I damn near had to remove all of the metal to make the holes big enough that I caould do the adjustment. I dont know of any other way to do it. If you're at .92 and it is running fine, I wouldn't mess with it.
