  2. Connect inductive timing light to No. 1 spark plug wire.
  3. Ensure idle speed is within specification. See IDLE SPEED  under IDLE SPEED & MIXTURE. Red (15° BTDC) mark on crankshaft pulley should align with pointer on front of engine. See Fig 2. If Red mark and pointer are not aligned, replace ECM/PCM. Timing g is not adjustable.
