Why is My Engine Misfiring?

CBAC Jan Engine Service 1If you’re just driving along and have the engine misfire while you’re on the road, it can be pretty scary. The reason for the misfiring is most often because a small, but very important, part of the car has begun deteriorating.

Today, the expert technicians at Christian Brothers Automotive in Springfield, Missouri are here to answer the question of, “Why is my engine misfiring?” Our automotive professionals will also let you know a few of the common reasons you may be experiencing these issues.

A Faulty Ignition Coil

The spark generated by the ignition coil ignites the fuel and air mixture in the engine that enables the car to start and run smoothly. If an ignition coil is not working properly, no spark will ignite the air and fuel mixture, causing a misfire. A bad ignition coil can severely damage the engine or catalytic converter. Ignition coils can be strained by worn spark plugs, which can ultimately lead to failure.

Worn Spark Plugs

Each time a spark plug burns, it erodes just a tiny bit. Over time, the amount of erosion will be greater than the amount of voltage necessary to generate a spark, which causes the spark plug to misfire. The wires inside the spark plugs could also begin to deteriorate and develop “cracks,” causing a leak current to other wires. This leak decreases the spark before it even reaches the plug.

Damaged Fuel Injector

What’s also referred to as “lean misfiring,” this type of engine misfiring occurs when there’s insufficient fuel in the combustion chamber. At times, only one cylinder will be affected by the lean misfire. The cause of a misfire could be a filthy, open, leaking, or shorted fuel injector. Another issue might be that the fuel injector driver circuit.

Vacuum Leak

When there isn’t enough compression, your engine won’t work correctly. A vacuum leak around the intake port gaskets of a cylinder could lead to a lack of fuel. Inadequate compression or fuel will make your vehicle’s engine continuously misfire until it’s repaired. Other causes of a vacuum leak could be an insufficient valve lash, a broken piston ring, or a leaking cylinder head gasket.
