Checking and adjusting the ignition timing (models before 1997)

Tools needed to check and adjust ignition timing

1. Warm up the engine to normal operating temperature.

2. Prepare the tools needed to check the ignition timing.

3. Connect a stroboscope.

4. On Ford Probe models, remove the jumper from the SPOUT connector located between the battery and the diagnostic connector. Connect the TEN and GND terminals of the diagnostic connector.

5. Start the engine and aim the strobe light at the setting ruler and the yellow mark on the crankshaft pulley. If the yellow mark does not match the desired mark on the setting ruler, unscrew the ignition distributor mounting bolt and turn the distributor as necessary.

6. Tighten the mounting bolt and check the ignition timing again.
