Why do fuel systems need to be cleaned?
Over time, gasoline hydrocarbons and certain additives found in some gasoline will build up on the surface of fuel injectors, intake manifold runners, intake ports and intake valves. Deposits in any of these areas can impair fuel economy and drivability, causing poor starts, stalling, hesitation, stumbling and decreased warm engine performance.
