An engine misfire is when one or more of your engine cylinders fail to produce power. The cylinders are where the air and fuel and mixture ignite. Misfires can happen when your engine is cold, warm, or intermittent, and they can occur for a number of reasons. Read on to learn more about what can be causing your car to misfire.
Engine misfires are combustion failures. Each engine cylinder must fire in a precise way and sequence to ensure smooth performance and efficiency. Some misfires dissipate, but you should never ignore the problem. Multiple misfires can cause extensive engine damage, so it is important you get the necessary repairs soon.
How to Tell If Your Car Is Misfiring
- Weak engine power
- Problems starting engine

What Causes Engine Misfires?
Now that you know the signs of misfires, you should know what causes them too. That is why taking your car to a trusted mechanic is important following the detection of signs. Below are some of the most common explanations for misfires:
- Ignition system problems - The parts affected can include the wiring, coil packs, spark plugs, and crankshaft position sensor.
- Fuel delivery system - Your vehicle requires a balanced air and fuel mixture. Failing or dirty fuel injectors can cause an imbalance and result in a misfire.
- Exhaust issue - Your emissions management system has many sensors that can fail which can cause misfires.
- Engine problems - These can include anything and everything in the engine, including sensors or pistons themselves.
