The factory fuel injectors in your vehicle deliver the perfect amount of fuel to the engine. They do this by using controlled valves to spray fuel into the engine. The valves open and close at precisely-timed intervals to provide the ideal air and fuel mixture needed for combustion. Most vehicles feature at least one fuel injector in each cylinder. Their function is a simple process. The fuel pump sends gas through the fuel lines to the injectors. An engine control unit, or ECU, then senses the right time for the injectors to spray fuel through the nozzles into the combustion chamber.
Even the best fuel injectors can begin to fail, though. They can eventually become clogged, which can lead to dangerous fuel leakage. If your engine starts misfiring, stalling, or idling rough, your injectors may need replacing. Other signs include those previously mentioned leaks, a failed emissions test, or worsening fuel mileage. You should have your injectors inspected during a routine maintenance appointment to ensure that they're operating properly. If they aren't, the solution is simple.
