Fuel injectors become clogged with dirt and rust, while the injector tips plug up with varnish from gasoline. Intake valves, combustion chambers and pistons suffer from carbon deposits, which if allowed to accumulate may lead to diminished performance, reduced fuel economy and poor/uneven idle. This service dissolves these deposits and restores proper fuel flow into the combustion chamber. The benefits range from optimizing fuel economy, cleaner emissions and improved engine responsiveness.
