TPS usually gives you problems when you are under power. At idle, I havnt seen a TPS give grief... Could be wrong though

TPS will give you a flat spot on accelaration at about 2000 rpm then again at 4500 rpm but will also give the car a hunting idle where it will idle up and down and some times stall

I See.... How does the ECU use and interpret TPS signals at idle?
