Most cars and light trucks produced after the late 1980’s use fuel injectors instead of carburetors. Injectors are sued because they are more efficient. Unfortunately their location in the engine puts them in the path of contaminates which build up on the injection and can drastically reduce their effectiveness. This can cause the engine to run poorly and reduce fuel economy.
Carbon cleaning service are designed specifically to eliminate the build of of contaminates. This works not only on the injectors but also cleans the intake plenum, intake valve stems, combustion change and even contaminated exhaust systems. In many cases you will experience a dramatic improvement in how your engine runs and as a side benefit know that your vehicle is producing far less harmful pollutants.
