Mitsubishi Eclipse Cross Fuel Injector Service Malaysia
The 4B40 direct injection engine uses high-pressure fuel injectors that spray directly into the combustion chamber. Over time, carbon deposits or injector wear can affect spray pattern, leading to rough idle, misfires, and increased fuel consumption. Injector cleaning can be performed via chemical additives or professional ultrasonic cleaning. A diagnostic scan identifying misfire codes for specific cylinders helps pinpoint which injector is affected. Replacement injectors should match OEM specifications for the direct injection system.
