Signs Your Fuel Injector Need Servicing

Warning signs will develop to alert you to the need to get your fuel injectors serviced. Among the most important signs to watch out for are:

• You will have trouble starting your vehicle. This happens when the injectors become clogged or the internal parts get worn out and cannot inject the right amount of fuel needed to start your vehicle.
• Your vehicle fails an emissions test. If the ratio of fuel to oxygen needed to efficiently operate your vehicle is not maintained, harmful gases will increase in the exhaust system. These gases will cause your vehicle to fail an emissions test.
• Fuel usage increases. A plugged or worn fuel injector will cause the car to provide more fuel to the system than is really needed and this will result in a lowering of the vehicles fuel efficiency.
• The engine will surge forward. As the bad fuel injectors struggle to provide the right amount of fuel, the engines RPMs will go up and down while you are driving.
• You will often start to smell gas fumes from unspent fuel because of the imbalance in the fuel to oxygen ratio. The smell could also come from leaks in the injectors.
• The engine will start to misfire when an injector becomes plugged. This can also cause the engine to vibrate.
• The check engine light comes on when the sensors detect a fuel/oxygen imbalance. This often indicates a fuel injector has gone bad and needs to be serviced or replaced.
