This was intended to alleviate problems with plug fouling between assembly line and customer delivery where most engine run times were minimal. This causes a misfire, a loss of power and fuel economy, and an increase in tailpipe hydrocarbon (HC) emissions. Carbon Fouled Spark Plug – Besthomegear.com. There was a period of time when new car manufacturers had the spark plug tips and porcelain, silicone coated to help keep soot deposits from clinging to the plugs. The heads have also had port work done. Since the method requires a minimum of technique and low-level skills, it is not normally recommended to novices. Could it be a air/fuel mixture problem?

Most of these failures, which usually accompany normal spark plug operation, can be minimized by good operational and maintenance practices. Carbon fouling occurs when the spark plug firing end does not reach the self-cleaning temperature of approximately 450°C (842°F). Dirty or fouled spark plugs can cause a misfire or a cylinder filing to fire at all. A heavy carbon fouled spark plug that is causing the engine not to run correctly cannot be repaired and needs to be replaced. Cleaning a Spark Plug.
