On my vafc, the throttle postion reout thingy sometime goes crazy. Sometimes it reads 100% when I am off the gas which it should, then sometimes it reads 95% then 92% or somecrazy number that isn't accurate. It doesn't always do this but here lately it has. Could somebody please give me some advice.

 

Check to make sure your wire connection on the TPS is a solid connection. Meaning that it's clean and tight.

If it still acts up then I would just suggest changing it with another one and see if it does the same. Jack that thing from the JY.
