Ignition Timing

NOTE: Timing instrument should be connected to number one spark plug using adapter or snap-on connector. Do not puncture spark plug wire or boot to make connection.
  1. Place transmission in "P" (auto. trans.) or Neutral (man. trans.). Turn A/C and heater off. Connect timing light and tachometer to engine. Disconnect single White wire connector near distributor (Black wire connector on some models) and warm engine to normal operating temperature.
  2. With engine at timing RPM, check timing. If timing is within 2° of specified timing, do not adjust. If not, loosen distributor hold-down bolt and turn distributor to adjust. Tighten bolt, then recheck timing. Remove test equipment. Reconnect connector wire.
