What does it means that a fine black powder builds up fast on my plugs and what should I do ? Thanks in advance Sorry, it's a Nissan Sunny 1992 petrol ignition > What does it means that a fine black powder builds up fast on my plugs and > what should I do ? Thanks in advance If it's a carburettor model then it could be the choke not releasing after the warm-up period, or a very dirty air filter, or a blocked small bore rubber pipe at the carburettor. Or you only use it for 1 mile journeys and there's nothing wrong with it that a 30 mile blast wouldn't sort out. > Sorry, it's a Nissan Sunny 1992 petrol ignition > > > What does it means that a fine black powder builds up fast on my plugs and > > what should I do ?

Thanks in advance A light black powder or soot buildup on the plugs is carbon fouling. It means you need what used to be called a tune up. heavy black powdery build up on the plugs mean in is running rich (excessive fuel mixture) could be any number of things causing it. > What does it means that a fine black powder builds up fast on my plugs and > what should I do ?
