Fuel Injector Cleaning
As part of our all-round EFI Diagnostic Service, we offer top quality EFI fuel injector testing and cleaning. This allows us to diagnose with absolute certainty such things as leaky injectors, poor spray patterns, electronically damaged injectors, mechanically damaged injectors, weak return springs, annular bore differences, solenoid winding differences and much more.
Injectors need to be cleaned in order to operate properly. Injectors which are contaminated at the seat will drip or spray when the computer thinks they are closed.
Our specialised injector cleaning equipment can pulse the injectors up to 9900 pulses per minute and that is the range necessary to carry out tests on the latest engines in the market today. Our injector cleaning service uses ultra-sonic cleaning in a mild detergent type cleaning fluid.
Why clean injectors?
Every time you stop a hot engine a small amount of residue adds to the already present build up on your vehicle's injectors. The more frequent the stops, the more rapidly the build up accumulates. This accumulation eventually reduces the flow of fuel through the injector and disrupts its spray pattern, causing the engine to run lean.
This can cause a number of problems, although the most common is driveability problems such as flat spots and hesitations.
Most fuels do contain detergents to clean the fuel system and injectors. However there is a limit to what they can achieve and it is sometimes necessary to use a more severe cleaner to remove long-term accumulations.
