Glazing appears as a yellowish, varnish-like colour. This condition indicates that spark plug temperatures have risen suddenly during a hard, fast acceleration period. As a result, normal combustion deposits do not have an opportunity to “fluff-off” as they normally do. Instead, they melt to form a conductive coating and misfire will occur.
