Uneven Firing Voltages:

^ Is the evenness of the spark plug firing voltage too wide and the average value of spark plug firing voltage greater than normal?

YES -- Problems affecting all cylinders:

- Check coil wire for proper installation in coil and distributor cap.

- Check for wide spark plug gaps at all cylinders, (usually from worn electrodes due to high mileage).

- Inspect cap and rotor for problems causing excessive cap-to-rotor gap.

NO -- GO to IGN6. IGN6 - Check Secondary Display (Continued)
