Throttle Body

  1. Install tube assembly using a new gasket. Install throttle position sensor. Before installing idle air control valve, measure distance between tip of valve pintle and mounting surface. Distance should not exceed 1 1/8" (28 mm).
  2. If distance is incorrect, exert firm pressure on pintle while moving pintle from side to side until distance is correct. The flange mounted IAC valve on 2.5L engines has a dual taper, 10 mm diameter pintle. Ensure replacement valve has same shape and diameter of valve removed.
