need help my tps is shitting out i think. i found this on zilvia it was an older post can anyone help me out with the shaving and rewire part. atleast elaborate on it please

Using a rb25 tps will work.

If you can't get a hold of one use a vh45/vg30/ tps with the corresponding idle switch, it will need small amount of shaving and a re-wire.

finding a RB Tps is a pain in the ass, junkyard to avoid the time finding one.

ok i didnt get much feedback. but i cleaned out the iacv and it didnt help. then i unplugged the brown plug off of the iacv. and it idled fine. but after reving the motor with it unplugged it seemed like it was bogging enough to just about turn off so i compensated with the idle screw in the side of the whole assembly.

is this okay to do?
