Wow. Dumb question: are you sure you've got both screws loose? This is an Andreas question, I'm afraid - if that thing stops at .55, the ecu is being told that the throttle is a bit open when it's actually closed. But while it's tempting to fault the tps, I really don't know. Make sure both top and bottom screws are loose and you can rotate the tps body freely - I must admit I never tried to back mine - um - from the driver's seat, clockwise very far, didn't need to. It went a good half turn (oops) counterclockwise when I hadn't loosened it up enuff and it 'popped' loose. Remember, if I didn't mention it, that you can fiddle with this thing with the engine not running. The tps doesn't care as long as you've got the ignition on to give it voltage. It's nothing more than a rheostat, I presume. How many miles on this engine (including the intake setup)?
