Fuel injectors play a critical role in a vehicle. They control the amount and time that fuel goes into the combustion chamber during the power stroke, thus ensuring optimum combustion and efficiency. However, without proper maintenance, the fuel injectors may develop some problems such as;
Developing Mechanical Issues
Developing Electrical Issues (malfunctions when receiving commands from ECU - Electronic Control Unit or Computer),
Clogging or Blockage Issues — due to accumulation of dirt and/or debris (*usually the most common injector problem)
It's critical to be alert at the signs of bad injectors so that you act immediately if and when they occur. Below are the most common symptoms of bad fuel injectors.
Check Engine Light Illuminates Solid or Flashes
One of the engine issues that can cause the check engine light to come on or flash is a dirty or malfunctioning fuel injector. This light can indicate an issue within the fuel injection system or GDI System. When a fuel injector is failing, it usually will create the symptom of either too much or too little fuel going into the engine (sometimes no fuel at all). The engine control unit (ECU) can detect any fluctuations in the fuel injected into the motor, and consequently, can trigger the check engine light to come on. For more information on how this system works or what could be going on with your vehicle call our knowledgeable service staff!
Rough Idling/Irritating Idle Noise
Typically, a car delivers a subtle rumble when at idle. If you notice that the sound has gone from low to a rough and unpleasant noise, it may be a sign of bad fuel injectors. That occurs when particles build up on the injector nozzles, thus affecting the amount of spray and atomization of fuel. Although the rough noise might also be attributed to dirty air filters and/or bad spark plugs and other components, it can also indicate problems with bad fuel injectors.
Engine Misfiring
If you've experienced engine misfiring or a delayed response when you step on the accelerator pedal, in can also be a sign of problems with fuel injectors. As with rough idle, misfires can also be caused by clogged fuel-injector nozzles.
The ECU works to monitor and control the fuel injected into the engine, and if the injector can't deliver the right amount at the right time, there'll be problems in the fuel-air mix within the engine's combustion chamber. As a result, the engine misfires, or you get a delayed acceleration response. Misfire codes such as P0300 (Random Cylinder Misfire), P0301 (Cylinder number 1 Misfire), P0302, P0303, P0304, P0305, P0306, P0307, P0308 can also indicate problems with fuel injectors.
Fuel Leaks
If there's a sharp and pungent smell of fuel in your cab while driving and your vehicle has one or two signs mentioned above, then there's a likelihood that you could have a fuel leak. Fuel injectors can start leaking when they are worn out or improperly maintained.
Fuel injectors are critical components in a car. Whenever you experience any of the above-mentioned symptoms, have a professional technician at Pickering's Auto Service in Lakewood, Co - Arvada, CO - Westminster, CO repair it to ensure optimum engine performance.
