have problem engine only running on 5 one plug fouls up any ideas please colin good site

Hello Colin,

what color is your spark ?
- black and humid, fuel not burned, spark missing.
- hell grey, no fuel injected.
- black with dust, oil is burned in the cylinder chamber.

Did you checked that you have spark at the end of this spark plug ? taking it out and fixing the spark plug at the end of the cable ? The problems could comes from the distributor.

Otherwise, it's possible that you have an injector that give you not the right quantity of fuel, try to exchange two injectors and you'll see if the problem has changed of place.

Bye
Michel
