What happens over the years, is the tps develops open areas that the ecm can't read. Since it doesn't know what the throttle position is, it can't deliver the correct amount of fuel. I suspect you have a bad spot or two in your tps. Possible water in the connection(s). Notice there are two screws that can be loosened to adjust the tps, but in your case, a simple adjustment won't help. Verify your results and check back.
Throttle rest is measured at 1.06v and full throttle is measured at 4.28v.

I got rid of my alluminum wings and picked up a Goldwing. Here to be a Light.
