There are different methods for cleaning dirty or clogged fuel injectors, but none are more effective than off-vehicle cleaning
Below are some different methods for cleaning your fuel injectors:
While these options are cheap, they may harm oxygen sensors, injector seals and your catalytic converter due to the harsh chemicals. Also there is no way to know if your injectors were actually cleaned or not as the only way to positively identify an inefficiently operating injector is to visually inspect and clean it off the vehicle.
On-Vehicle cleaning performed at a shop
This method is performed by some car dealers and oil change stores. It is done by forcing a cleaning solution into the fuel rail in an attempt to clean the injectors while the engine is running. This method, as with pour-in-the-tank cleaners subjects your oxygen sensors, injector seals and your catalytic converter to even more concentrated amounts of these harmful chemicals. It is also very expensive at up to $150 with no guarantee that your injectors will actually be cleaned. And again, the only way to positively identify an inefficiently operating injector is to visually inspect and clean it off the vehicle.
Professional off-vehicle cleaning
This method is by far the most effective way to clean dirty or clogged fuel injectors. They are flow tested and ultrasonically cleaned using state-of-the-art Fuel Injector Cleaning Technology. Trust a Professional Fuel Injector Cleaning Company like ProFlow to get you going.
