Auto Parts That Can Make Your Engine Sputter When They Go Bad

Did you know that your car, truck, or utility vehicle’s engine might start to sputter when certain auto parts go bad? Willoughby Hills Auto Repair can figure out why your engine is sputtering and repair the problem. We may need to replace a part, or it may be something as simple as flushing a hose. Let’s talk more about engine sputtering below and the faulty parts that can cause it.

Catalytic Converter

For example, if your catalytic converter gets clogged, the engine’s exhaust will make its way back into the combustion chamber. Once the combustion chamber is full of exhaust, the engine will have difficulties producing new combustion. Unfortunately, this will make your engine sputter. We will need to replace the catalytic converter to resolve the problem.

Filters/Hoses

Clogged filters and hoses can also cause your engine to sputter all the time. For example, if the fuel filter is clogged, the engine may be starved of fuel and running on a lean fuel mixture. The same is true if the fuel hoses are clogged. Replacing the fuel filter every 30,000 miles helps to prevent this problem. We may be able to flush the fuel lines if that’s the problem.

Fuel Pump

A malfunctioning fuel pump will also place your engine in a fuel-starved condition. Again, when this happens, the engine sputters and struggles to run because it does not have enough fuel to burn. In the case of the fuel pump, we will need to replace it.

Mass Airflow Sensor

The mass airflow (MAF) sensor can also make your engine sputter if it convinces the engine control module that the combustion chamber needs more air when it actually doesn’t. This can happen if the mass airflow sensor malfunctions because it is dirty. In most cases, we can clean the mass airflow sensor. In rare cases, we may need to replace it.

Oxygen Sensor

The oxygen sensor is also called the O2 sensor. This sensor lasts about 100,000 miles before it malfunctions and needs to be replaced. As with the MAF sensor, the O2 sensor can convince the engine control module that more air is needed in the combustion chamber when that actually is not the case. This extra air will make your engine sputter.

Spark Plugs

Finally, your engine will sputter if it’s time to replace the spark plugs. In fact, it may also stall frequently, especially when you are sitting at an idle. Replacing the worn plugs will resolve the problem, and we may also need to replace the plug wires.
