Can you clean fuel injectors? Many injector testers have a cleaning function, which can eliminate some deposits. But cleaning multi-point and high-pressure injectors can cause: Failures from aggressive additives in the cleaning fluid Thermal damage to the solenoid as a result of incorrect triggering currents Voided warranty claims or part guarantees
Fuel injectors are an essential engine component. Malfunctions can lead to serious engine damage – which is why faulty injectors have to be recognized and replaced as quickly as possible. Only properly functioning injectors can provide motorists with an assurance of: Minimized fuel consumption Significantly improved starting performance Immediate acceleration Longer service life for exhaust components
While no maintenance is needed on injection components themselves, keeping fresh clean gasoline in the fuel tank and changing the in-line filter per the manufacturer’s recommendations are good practices.
