Rotating throttle position sensor increases voltage? How did you determine that? (Only asking because I don't see anything in the service manual in this regard.) And increased voltage alleviates the stumble?
I was going to respond to OP with the comment that 2500 is too low to rev this engine, but of course everyone has to pass through this range when moving off from a start in 1st gear.
