Disassembly (Throttle Body Cover Model 220)

  1. Place throttle body on Holding Fixture (J-9789-118 or BT-30-15) to prevent damage to throttle valve. Remove cover-to-throttle body screws (note location of 2 short screws). Remove throttle body cover. See Figure. Throttle body cover and pressure regulator are serviced as an assembly. DO NOT  remove pressure regulator-to-cover screws.
  2. Remove TP sensor, IAC, fuel injectors, fuel filter, rubber parts, and diaphragms. Clean all remaining (metal) parts in a cold immersion-type cleaner such as Carbon X (X-55). Blow dry with compressed air. Inspect mating surfaces for damage which may prevent gasket sealing. Repair or replace faulty components.
