Failure Symptoms

Uneven engine running, particularly at idle, and a noticeable loss of power are common initial symptoms of a faulty fuel injector. If left unaddressed, this can lead to increased fuel consumption, excessive black smoke from the exhaust, and potential damage to other engine components due to imbalanced combustion. Continued operation risks incomplete combustion and cylinder washing.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously clean and free from any carbon deposits before installing the new injector. Avoid rotating the injector during insertion, as this can damage the sealing surfaces.

Service Note

Inspect the fuel lines, seals, and the engine's fuel filter when replacing a fuel injector.
