It really doesn't matter. As long as you get a resistance that goes from high to low for the full range of movement of the throttle. That will convert the 5v you put into it into a voltage that goes from low to high.

rather change the Throttle body, from the description above its the root of all your problem....does the throttle body idle motor buzz and move slightly when you turn the ignition on, if not then the TB is toast....rather change that instead of changing the entire engine management
