If your engine sputters every time that you drive your car, truck, or utility vehicle, there is something wrong underneath the hood. Forgive us for stating the obvious, but we want to assure you that we can help here at Accurate Auto Center. We are going to list the common reasons why engines sputter below. The good news is that we can fix any of these issues.
Clogged Catalytic Converter
As you probably already know, the catalytic converter treats your engine’s exhaust to make it safe for release into the environment. If the catalytic converter gets clogged, the exhaust backs up. This impedes engine combustion and makes your engine sputter all the time.
Clogged Fuel Filter
A clogged fuel filter might also be the culprit. You need to have the fuel filter changed every 30,000 miles to make certain that fuel makes its way easily into the combustion chamber. If the filter is clogged, you may have little fuel heading into the chamber.
Clogged Fuel Lines
This creates a lean fuel mixture as do clogged fuel lines. Any time there is more air than fuel in the combustion chamber, your engine will sputter. It will also struggle to accelerate and operate smoothly at high speeds.
Faulty Fuel Pump
A faulty fuel pump can create a lean fuel mixture. If the pump is not drawing enough gasoline or diesel fuel out of the tank and pushing it through to the engine, your engine will become fuel-starved. When this happens, it sputters, especially when it is under stress.
Malfunctioning MAF Sensor
The mass airflow sensor keeps track of the incoming air from the outside. It reports this information to your automobile’s main computer chip. If it malfunctions, the computer chip may add air to the combustion chamber when it doesn’t need it. This will make your engine sputter.
Malfunctioning O2 Sensor
The same is true with the oxygen sensor, although it performs a different task. The O2 sensor measures the oxygen that is found in the exhaust. It also reports this information to the main computer chip. A faulty O2 sensor can report incorrect information.
Worn Spark Plugs
Finally, your engine will sputter all the time if your spark plugs are worn. This is because the engine is misfiring. In extreme cases, your engine might also stall, especially if you are sitting at an idle and the idle is rough. Replacing the plugs usually solves the problem.
