There are many potential causes of a misfiring engine. Some of the most well-known include issues with worn out spark plugs, a weak pressure through the fuel injectors, a vacuum leak, fatigued valve seals, or even issues with the power going to the engine coil. Whatever the reason behind a misfiring engine, you’ll want to get eyes on the problem as soon as possible, as it can rapidly get worse, causing associated systems and parts within your engine to suffer damage. What are some of the most common causes and symptoms of a misfiring engine?

Engines are the powerful centre of your car. You put your foot down, fuel surges into the cylinder heads and away you go. However, despite its importance, it’s all too easy to overlook problems with the engine, and turn a blind eye to some of the warning signs. Left unchecked, many of these can lead to a breakdown (leaving you stranded miles from home) or worse still, to a bank-balance breaking repair bill. In the most extreme cases engine problems can leave the car beyond viable repair – which then means you’ve got to go to the trouble of spending time finding and shelling out your hard-earned cash on a new vehicle.

To avoid the hassle and expense of experiencing engine failure, watch out for these minor and major warning signs to keep the costs of repair down.

Unless you are still a novice driver, you should not really be stalling your vehicle (save for the occasional moment where your motoring skills suddenly go on holiday). But if your car starts regularly stalling, then you may have an underlying problem with the air flow, fuel system or electrics.  

And when stalls happen on the open road they can be downright dangerous. What’s worse is that they’re always unexpected; stalls come with no warning signs. The check engine light doesn’t illuminate on the dash board and no signs come out of the engine. You could even be motoring on quite dandily and then bang out of nowhere, the stall happens. 

If you are experiencing stalls on a regular basis when you’re on the road, then you may want to get the car checked out.

Spark plugs are an integral part of the engine. Each one sends a little high voltage spark between the terminals, which is used to ignite fuel in the engine. When spark plugs fail, this means that your engine will stop running efficiently.

Over time spark plugs can become dirty, picking up a residue from the burned fuel, coating the electrodes with carbon. Additionally, repeated sparking of the metal components can simply wear them down, increasing the distance the spark has to jump between electrodes, requiring additional charge from the battery which is not always available.  In short, spark plugs will wear out.
