Engine Misfiring

A misfiring engine can cause anything from sudden jerks and loud stutters to an almost immediate and temporary loss of power,  which can be extremely scary when driving on the freeway. Therefore before this happens it is important to know what is wrong with the ignition. is what it means, what causes it, and perhaps most importantly, what you should be doing to prevent it or keep it from happening again. We will look at each of these points in this blog.

What is engine misfire?

Engine misfire is  what happens when the expected combination of air, fuel and a pressurized spark fails to combine  to create the desired explosion to get your engine running. Instead, early or late failure occurs. Explosion or blast producing that loud unexpected bang. This abnormal popping sound is called a misfire and it can potentially cause your entire car to suffer.

 What Causes  Engine Misfire?

 Engine misfire can be caused by a number of different causes.

After all, your engine depends on dozens of parts and systems working together simultaneously with precise timing  to run as intended. If you think about it, modern engines run reliably and smoothly for as long as they do at such a high speed. The timing and integrity requirements of the part are nothing short of a marvel of modern engineering. As you can imagine, this means that there are a number of different things that are fairly common causes of misfires, but almost all of them can  be put into one of three different categories: your fuel system, your ignition system,  or some other mechanical cause.

 Your ignition system: When air and fuel combine in your cylinder, they need a spark  to ignite  and cause the explosion that gives you  the power you need. If they don't get that blast, the cycle continues and more air and fuel are combined.

In most cases, this simply means you have a bad or intermittent spark plug (an  ignition coil problem is also very common). As spark plugs wear out and corrode, they lose their ability to fire on command. In most cases, replacing the spark plugs will solve a misfire problem. You should also check the ignition wires to make sure they are not corroded or frayed.These are also easy and inexpensive to replace. 

Your fuel system: If your ignition system fails, move on to your fuel system. You drive at highway speed. A misfire could be due to not getting enough fuel  into your cylinder, causing an oxygen-rich explosion. There's also a slim chance that you  simply filled  your car with a tank  that went bad. 

There are a number of components that regulate the amount of fuel that goes into a cylinder to ensure it is working properly. We recommend seeing a trained technician to check all possibilities. Mechanical System Problems - Finally, mechanical problems could be  causing your misfires. First check the vacuum lines connected to the intake manifold to make sure they are not leaking or cracked in any way.

There is also a possibility that the timing belt or chain has cracked or slipped. Regardless of the mechanical cause, these are not problems that will go away on their own.
