Ignition Timing: Cr-V

  1. Set parking brake. Start engine and ensure idle speed is correct. See IDLE SPEED & MIXTURE .
  2. Turn ignition off, connect SCS Service Connector (07PAZ-0010100) to 2-pin service check connector located under instrument panel, on right side of center console. See Figure. Service check connector uses a Brown wire and a Black wire.
  3. Connect tachometer. Run engine at 3000 RPM with no electrical loads (headlights, blower motor, rear defogger, A/C and cooling fan off) and transmission in Park or Neutral. When radiator cooling fan comes on, allow engine to idle.
  4. Connect timing light to No. 1 spark plug wire. Check base ignition timing at specified engine idle speed. See IGNITION TIMING (DEGREES BTDC - RED MARK @ RPM)  table. Red mark indicates degrees Before Top Dead Center (BTDC). White mark indicates No. 1 cylinder Top Dead Center (TDC). See Figure.
  5. If timing is not as specified, loosen distributor hold-down bolts and rotate distributor to adjust timing. Rotate distributor counterclockwise to advance timing and clockwise to retard timing. Tighten distributor hold-down bolts to 18 ft. lbs. (24 N.m). Check timing after tightening distributor hold-down bolts. Remove timing light, tachometer and SCS service connector.
