The average lifespan of fuel injectors is 50,000 miles to 100,000 miles, but this depends on how well you take care of your automobile and the type of fuel that you use. Less expensive fuel might contain more sediment that can clog your fuel injectors, especially if you don’t change your fuel filter regularly. Journey Auto Repair is going to list the signs of clogged or leaking fuel injectors below. If you are experiencing any of these problems, bring your vehicle to our shop right away.
Dancing Tachometer Needle
If the fuel injectors are partially clogged, they will release gasoline into the cylinders in spurts. This can cause your engine’s RPMs to rev sporadically and, as a consequence, you’ll end up with the dancing tachometer needle. It’s important to note that a vacuum leak can also cause the tachometer needle to bounce up and down. Either way, we can fix the problem.
Hard Starts or No Start
Whether the fuel injectors are clogged or leaking, you may find it difficult to get your car, truck, or utility vehicle started. This is because the engine is not getting enough fuel or getting too much fuel, respectively. Eventually, as the problem gets worse, you may not be able to get your automobile started at all. If we catch the problem before it gets too bad, we can help you avoid this.
Misfiring/Sputtering Engine
Faulty fuel injectors can also cause your engine to misfire and sputter. When this happens, you may find it difficult to maintain higher speeds or to accelerate. This is a sign that your engine is not getting enough fuel. A clogged fuel filter, problems with fuel delivery, or a faulty mass airflow or oxygen sensor can also create a sputtering engine as can worn spark plugs.
Poor Fuel Economy
The more your engine struggles to run the more fuel it will use up. If your fuel injectors are leaking, the engine will burn away the excess fuel. Either way, you will notice a reduction in your fuel economy until you get the fuel injectors cleaned or replaced.
Rough Engine Idle
Finally, if the fuel injectors are clogged or leaking, they can also affect your engine’s idle. While you are sitting at an idle, you may feel the engine stuttering and struggling to keep running. This can be a sign that your fuel injectors need some professional attention at our shop.
