Multiple causes related to electrical and mechanical engine components, or poor fuel quality in combination with unfavorable driving behavior (low loads and short driving distances). This condition may lead to possible clogging of the injector tips, causing a disturbance of the fuel spraying pattern or excessive carbon deposits on the intake valves/ports, resulting in reduced air flow into the combustion chambers."
