A fuel injector works in partnership with the fuel pump and has the sole responsibility of transporting the fuel from the tank to the engine. Fuel Injectors are expected to have a life expectancy of over 1 billion cycles yet variables such as driving conditions, air pollution and contamination from road debris can bring its life cycle to a premature end.
Telltale signs your fuel injector has gone bad are engine misfiring, stalling or hesitation and a reduction in vehicle performance or MPG. If you are experiencing such problems it is vital you address the issue immediately to avoid fuel line problems which can lead to engine damage.
If your fuel injector has reached the end of it’s life cycle, it can be easily replaced at low cost with moderate mechanical knowledge.
