Lastly, I have both a Red and a Black Throttle Position Sensor. Which should I use and what is the difference? I should explain this is a different engine to the original so I have a couple of duplicate parts.
The red tps is an original 2wd sensor designed to work with a L6 ecu (std 2wd) The black one is from a later 4x4 car running an L8 ecu. (std 4x4)
