Product Information

Engine Misfires: When the fuel injector o-rings fail, they can cause fuel to leak into the combustion chamber, leading to engine misfires. If you experience rough idling, hesitation, or a loss of power, it could be a result of o-ring failure.• Follow Manufacturer’s Maintenance Schedule: Each vehicle has a specific maintenance schedule recommended by the manufacturer. It is important to follow this schedule and perform regular maintenance tasks, such as fuel filter replacement, to ensure the fuel system and fuel injectors are in optimal condition.

Fuel injector leak testing should be done under operating pressure. The average DIY fuel injector cleaning project and most automotive repair shops does not have the proper diagnostic equipment or the ability to test leaking injectors or clean them properly. It is suggested that you have your leaking fuel injector sent to Injector RX for testing and cleaning. Fuel Injection Systems: If you are using a “generic” code reader, then you can expect to see codes, beginning with P02. (generic, not vehicle manufacturer specific). For example, a fault with an injector in cylinder one, would give a code of P0201. These are all, fuel & air metering injector circuit related codes.
