Seven Reasons Why Your Engine Is Sputtering

A sputtering engine is unnerving and a clear indication that something is wrong. The sooner you get the problem fixed the better. Some of the causes of engine sputtering can damage the engine further, not to mention eat up the fuel you have in the gas tank. Buckeye Complete Auto Repair can fix your sputtering engine. Here are seven reasons why it might be doing it.

1. Catalytic Converter

The catalytic converter is responsible for turning poisonous carbon monoxide into the much safer carbon dioxide before it’s released through the tailpipe. A failing catalytic converter can cause your engine to sputter, overheat, and smell like rotten eggs. What you’re actually smelling is sulfur.

2. Exhaust Manifold

The exhaust manifold is the first engine part to handle your automobile’s scorching engine exhaust. If it’s leaking, your engine can sputter and overheat. You might also hear hissing or tapping. This sound is more prominent when your engine is cold and it’s the exhaust escaping from the manifold.

3. Fuel Injectors

Fuel injectors get clogged as the engine burns gasoline. Carbon is a natural byproduct of gasoline engines, and it builds up on the fuel injectors. Clogged fuel injectors will make your engine sputter because they cannot spray enough gasoline into the cylinders or engine’s intake manifold.

4. Gaskets and/or Seals

An exhaust or vacuum leak in the engine will cause it to sputter. It’s less expensive to replace a worn gasket or seal than it is to replace the engine part it could damage. For example, a cracked exhaust manifold gasket can damage the exhaust manifold, which is much more expensive to replace.

5. Oxygen (O2) Sensor

The oxygen sensor is one of many parts that help determine how much fuel should be pushed through to the engine. If the amount of fuel is off, either too much or too little, your vehicle’s engine will sputter. Too much fuel can flood the engine and too little fuel will starve it and reduce its power.

6. Mass Airflow (MAF) Sensor

The same holds true with the mass airflow sensor. This part is responsible for monitoring the amount of air in the engine. Your vehicle’s engine mixes air and fuel to combust (burn) and run. If the amount of air is off, the fuel level will be affected as discussed above – too rich or too lean.

7. Spark Plugs

The spark plugs are an important part of your engine’s combustion. They ignite the air and gas mixture in the combustion chamber to fire up the engine and keep it running. Dirty, old, worn, or misplaced spark plugs can cause your engine to misfire – sputter – and even stall if the plugs are really bad.
