Most modern vehicles have fuel injectors instead of carburetors. A fuel injector is a vital component of the car engine because it delivers fuel into the cylinders while controlling fuel atomization, timing, and other important parameters.
If your vehicle performs poorly and you experience rough riding or lousy gas mileage, the problem could be with the injector system. To be sure, look out for the following symptoms.
1. The Car Engine Misfires
When your car engine misfires, it could mean that the fuel injector is dirty. This problem will cause the car to sputter and vibrate. This occurs because there's a problem with the air and fuel mixture entering the engine.
2. Rough Idle
When your vehicle shakes and sputters when you are stuck in traffic or when at a Stop sign, it may also mean that your fuel injector is dirty. Rough idling results from varying RPMs (revolutions per minute) even if your foot is not on the pedal. In most cases, rough idling may cause your engine to stall.
3. Poor Gas Mileage
If you've been using your car for many years, then you know approximately how far you can go on a gallon of fuel. If the mileage keeps decreasing, it means the engine is not performing optimally, and one reason could be a bad injection system.
Well, you can't be sure about this until you let an expert check your engine. This is because there are many other reasons for poor gas mileage.
4. Your Car Cannot Start
Your car needs fuel to start and move. A bad fuel injector can't deliver fuel into the cylinders. If the engine can't get fuel and air, it won't start. If your car cannot start, first check whether you have gas. If yes, then your injector could be the culprit.
