hi just a quickie simon , hopin you can help, i took my moiter out and put it in my new car, i took the plug off the back anyway now the throttle is readind in reverse , ie when no throttle is on it read 100% and then when i press the throttle it goes from 100% down to whatever i press the throttle, does this sound like i have put a plug back on incorrectly??? any advise appreciated, everything else is workin ok on it, it worked pefect before in my old car
