It’s extremely frustrating if your engine is sputtering all the time, especially when you are driving at faster speeds. York Tire & Auto Service is going to list common problems below that will make your car, truck, or utility vehicle’s engine sputter. Bring your vehicle to our shop in will find out what the problem is and fix it.
Clogged Fuel Filter
If your fuel filter hasn’t been changed in 30,000 miles, it’s likely clogged by sediment and this could be preventing fuel flow into the engine. This starves the engine of fuel and causes it to sputter and the acceleration to lag. Replacing the fuel filter generally resolves the problem.
Clogged Fuel Injectors
The same is true with your fuel injectors. If they are clogged, fuel is not making its way into the cylinders to be burned with air. There are over-the-counter fuel injector cleaners, but they don’t do as good of a job as a professional fuel injector cleaning does. A professional cleaning reef stores the injectors to like-new condition.
Faulty Fuel Pump
Another thing that can cause your engine to sputter, especially at high speeds or when it is under stress, is a faulty fuel pump. The fuel pump lasts about 100,000 miles before it needs to be replaced. If you drive a high-mileage automobile, it’s possible that your engine is sputtering because the fuel pump is not working as well as it should be anymore.
Faulty MAF Sensor
The mass airflow sensor can also indirectly cause your engine to sputter. If it is dirty or malfunctioning, it cannot send information regarding the engine’s incoming air to the engine control unit. Consequently, the engine control unit will make adjustments in the combustion chamber that can affect your vehicle’s performance. In other words, the adjustments will make your engine sputter.
Faulty O2 Sensor
The same is true with the oxygen sensor. This part lasts about 100,000 miles in newer automobiles. If you drive an older automobile, you probably won’t get one hundred thousand miles out of the oxygen sensor. Either way, when it goes bad, your engine can sputter.
Finally, a vacuum leak will fill the engine with air. This starves the engine of fuel and makes your engine sputter and your acceleration lag. Replacing the leaking vacuum hose generally solves the problem.
