On all 4-cylinder engines using the conventional distributor with vacuum advance, the air gap setting in the distributor should be checked and adjusted before the ignition timing is adjusted.

  1. Disconnect the negative battery cable.
  2.  
  3. Remove the distributor cap, O-ring and rotor.
  4.  
  5. Use a feeler gauge to measure the air gap at the pick up coil projection. The gap should be 0.008-0.016 in. (0.20-0.40mm) for the G200Z engine, or 0.012-0.020 in. (0.30-0.50mm) for the 4ZD1 engine; adjust it if necessary.

  7. Loosen the screws and move the signal generator until the gap is correct. Tighten the screws and recheck the gap.

The electrical parts in this system are not repairable. If found to be defective, they must be replaced.
