EFI stands for ELECTRONIC FUEL INJECTION
The Electronic Fuel Injection system fitted to most modern vehicles combines sophisticated computer controls with a high pressure fuel delivery system to provide optimum power and fuel efficiency. The system is controlled by an electronic control unit (ECU).
These systems often have anything in excess of thirty different engine and emission sensors all sending information continually to the ECU.
The ECU then monitors the information from the sensors and ensures the correct amount of fuel and air is used to provide optimum fuel efficiency and performance and also minimise exhaust emissions.
COMMON PROBLEMS
EFI problems can be caused by dirty fuel or a blocked injector. Sometimes however, the fault has to be found somewhere within the EFI system using advanced diagnostic testers. Common symptoms include; poor fuel economy, backfiring, ‘running on’ when the car is turned off and rough idling.
SYSTEM MAINTENANCE
Regular system cleans will ensure peak efficiency, but remember a tune up or serviceis maintenance for your vehicle and not a repair for a specific fault within an EFI system. Please ensure you advise your Repco Authorised Service Centre if you are experiencing any particular fault or problem, as they are fully trained to carry out a complete EFI service and restore your engine to its peak running condition using quality components from leading manufacturers such as ACA, Bosch, and Injectronics.
We are happy to answer any more questions you may have regarding EFI engine management or fuel systems.
