A bad car injector will have struggle to fight off foreign particles that will clog the injector. When the particles reached a certain amount, the injector cannot supply the fuel completely for a couple of times when it is required to. This will give a lower performance especially on the engine.

4. Your car is leaking its fuel

Fuel injectors can be damaged both from the inside and outside. Internal chokes will damage it from the inside, as outside damage may be caused by external cracks developed on the exterior body part of the injector. This type damage is quite common especially on intake manifold injector. Fuel leakage will occur if there is a crack on the injector. The fuel will flow through the body and nozzle, so you can easily see and smell it. Poor engine efficiency will occur because the fuel is not atomized or sprayed, instead it will flow in droplets form, making a weak air fuel mixture.

5. The car is not that ‘quiet’ and ‘calm’ when it is idle

Of course, bad fuel injector will cause a drop of performance during driving. Another thing you should know if your car has damaged injector is that it can affect idle engine. The abnormal and abrupt fuel supply will cause a rough and irregular engine idle. It is recommended that you should change the injector because in a long term, you may deal with a bigger problem.
