Checking Ignition Timing

Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle. Locate 2-pin service check connector (behind right kick panel). Install Service Check Connector Tool (07PAZ-0010100 ), into service check connector. See Fig 1 .
Connect inductive timing light to No. 1 spark plug wire. Ensure idle speed is within specification. See IDLE SPEED . Red (16° BTDC) mark on crankshaft pulley should align with pointer on timing belt cover.

If Red mark and pointer are not aligned, adjust base ignition timing by turning distributor. Rotate distributor counterclockwise to advance timing and clockwise to retard timing. See IGNITION TIMING . Tighten distributor mounting bolts to 16 ft. lbs. (22 N.m) Remove service check connector tool from service check connector.
