A method and apparatus for removing internal carbon deposits and related residue and contaminants from fuel injected and carbureted internal combustion engine systems by delivering fuel to the inlet of the engine fuel pump while the engine is cranked by battery power to start the engine and then delivering an engine conditioning fuel, which is a mixture of normal engine fuel and a carbon cleaning agent, to the fuel pump inlet so that the conditioning fuel passes through and removes carbon deposits from the engine fuel injectors or carburetor, as the case may be, and is then combusted in the engine cylinders to power the engine. The effectiveness of the carbon cleaning operation is determined by monitoring the flow rate of normal engine fuel to the engine.
