how do you adjust the tps(throttle position sensor) do you just undo the retaining screws and turn it clockwise can you play it by ear or do you need electronic equipment when i stop at the lights the car will idle at 900 in d and then drop about 200 or so and if i try to bring the idle up it will still keep trying to drop down to 700 and it will just keep going up and down please help me its a tp magna but has anyone adjusted there tps what happens

to adjust it, yes it is just loosening the screws and moving it, however i dont think it can be done by ear, it requires a miltimeter. It tells you how to in your gregories (i assume everyone has one lol)
