There are times when you tend to experience certain signs that your car is behaving weirdly. Upon getting it checked with your mechanic, you might not get hold of the actual problem at times. You might think that the problem is resolved, but there would be some other problem hidden.
Spark plugs are the tiny devices which are not known by maximum number of vehicle owners. When some problem occurs in your vehicle, you always get your hands on the engine ignoring the fact that there are other small parts which might be at fault too. Engine misfiring occurs when the car’s engine skips over one of the processes of its combustion cycle. There are 4 things which require working to make the cylinder fire properly, i.e. air/ fuel mixture, good compression, proper timing and the right spark. Misfiring generally causes the engine to run rough or jerk.
Causes of Misfiring
It is a fact that if any one of the four things aren’t in a proper working condition, then there is a risk of misfiring. There are various reasons which causes engine misfire which then keep the cylinder from combusting properly. Some of the reasons are listed below:
1. Fouled or Faulty Spark Plugs: It is the spark plugs which provide the spark for the ignition if air/fuel mixture inside the combustion chamber. But it doesn’t mean that they cannot go bad. Spark plugs going bad is the major reason which causes engine misfiring. They can go bad due to oil leaking into the combustion chamber or from carbon buildup around the tip of the spark plug. They often wear out quickly due to improper spark plug gap and overheating.
2. Cracked Distributor Cap: It is the distributor which controls the timing of the spark. The spark to each spark plug is sent at just the right time with the presence of a healthy distributor. If there is a crack or damage in the distributor cap, this will cause a loss in the signal to one or more spark plugs, resulting in a misfire.
3. Lack of Compression: A lack in the compression inside the cylinder doesn’t allow the spark from the plug to ignite the air/fuel mixture. This is mostly caused by leaky exhaust valves or blown head gasket.
To avoid the condition of engine misfire, you must follow the scheduled maintenance in your manual. You must also ensure that your vehicle’s engine is well tuned. A precaution beforehand is better than a cure later.
