Keeping your car in good running condition means never ignoring problems like engine misfires. You need to understand what causes this issue so that you can keep your vehicle properly maintained. Procrastinating with these critical issues could cost you a lot later on. Let’s take a look at this important car maintenance topic.
What Is an Engine Misfire?
If one or more of the engine cylinders is not producing enough power, it can cause a misfire. Some signs of an engine misfire can include:
- Slow acceleration
- Shaking during acceleration
- Engine hesitation
- Loss of power
- Strong vibrations during idle
- Bad gas mileage
- Check engine light
Why Is My Car Engine Misfiring?
It is important to find the cause of the misfiring so that you can deal with the car engine misfiring issues. Remember, this is not something you should put off. This can be a serious mechanical issue that needs immediate attention.
The first step is to check the codes on your diagnostic system. You can do this with a scan tool or have it done at a local shop. Codes do not always pinpoint exactly what the problem is, but this is still the best place to start. The code information can give you an idea of what types of mechanical issues are going on.
In many cases, misfiring happens because spark plugs have worn out. Even the modern spark plugs used today will wear out after about 100,000 miles.
Another common cause could be a fuel injector clog. This can be caused by dirt or carbon buildup. If the fuel injection system cannot deliver the fuel effectively, air will get trapped in the combustion chamber which will cause a misfire.
Vacuum leaks can also cause misfires. There are many small hoses inside the engine. These enable air to flow properly, but even a tiny pinhole can cause problems and cause misfires.
Beyond mechanical issues, an emissions system problem could also be the culprit. Today’s modern engines use a lot of computer information. If that information is off somehow, it can cause problems in the engine, resulting in misfiring.
How To Deal With Engine Misfiring
If you can determine the cause of the misfire on your own, and you are capable of solving the issue, you should do so quickly. Procrastination is not your friend when it comes to vehicle maintenance.
If you are not able to determine the cause of the misfiring, or you are not able to solve the issue yourself, you should find a reliable mechanic who can assist you. If you do not deal with this problem in a timely way, it will definitely cost you more money in the long run.
