xxx TPS - throttle position sensor
you need to reset this, start off with it turned fully anti clockwise and set your idle and throttle stop screw THEN set your TPX by putting a 20 thou feeler gauge in between the throttle stop screw and the part it comes down on, it should come out of idle mode and into throttle mode when you put the gauge in there and when you take it out it should return to idle xxx
hope this helps
