Hi,
Serviced my car over the weekend and found that the No 5 spark plug was
snow white while the rest looked normal. We run leaded fuel in Africa.
My guess is either a faulty injector (not so bad) or leaking exhaust
valve (very bad). I am sending the car for a compression test today.
Any other possible causes for a lean cylinder?
