Of course, driving around while your car is like this is not a very good idea. You know something is wrong and now you need to take the time to figure out just what it is. So, take a look at the information below.

Potential Reasons for Check Engine Light Coming on

The check engine light on your car is an important part of your vehicle’s diagnostic system. This is going to show up when your car is experiencing some problems. If this light comes on, then you know that something bad is going on with your car. It’s going to be best to get things diagnosed before continuing to drive it.

This light will come on for various different reasons. It comes on to tell you that a problem is present, but you aren’t going to know what that problem is without getting things checked out. There are many potential reasons why your check engine light is coming on. Diagnosing things is not going to be easy without the right equipment.

Your check engine light could be coming on due to:

  • fuel pump issues
  • motor problems
  • issues with various sensors
  • problems with an actuator
  • irregular voltage output
  • and many other reasons

There is a laundry list of reasons for why this light can come on. That is why it’s so important to get things diagnosed by a true professional. It’s going to make it easier to determine exactly what is going on.

When this check engine light issue is combined with the symptom of car shaking, it’s a bit easier to narrow things down. Even so, car shaking itself can be caused by many different things. It’s also possible that the car shaking isn’t the only reason why your check engine light is on. You need to have things thoroughly analyzed to get your car fixed up right.

What Do the Different Check Engine Light States Mean?

You’ve probably already noticed that there are different check engine light states that you can see from time to time. You might see your check engine light blinking or it could be flashing intermittently. Sometimes, a check engine light is constant as well. All of these different states indicate something different.

There is some basic information that I can give you, though. If you’re experiencing:

  • A constantly illuminated check engine light with no flashing, then this is indicative of something completely failing. You might need to replace a part, such as a faulty sensor, to get the light to disappear.
  • A steady check engine light is supposed to indicate a problem, but it might not be a true emergency.
  • When your check engine light is blinking, this means that there is some type of problem that is coming and going. It means that whatever is wrong comes and goes. This occurs when issues only happen in certain situations. For example, your check engine light might blink on when you’re going at a certain speed.

These are just basic information, so, if you want to determine what is really going on with your car, you need the right tools to read the code that is your car’s diagnostic system putting out. People without the right equipment have to take their cars to mechanics or dealerships when they’re experiencing issues such as this.

Why Is Your Car Shaking?

Car shaking issues can be very disconcerting. Some of these problems can be so bad that it’ll feel like your car is about to come apart. There are actually several potential causes for this problem that you’ll need to examine:

  • broken engine mounts (This is one of the most common causes for severe car shaking, so if your shaking issue is very pronounced, this could be the reason why it’s happening.)
  • air system issues
  • faulty spark plugs
  • car misfiring issues
  • bad fuel pressure

Like mentioned above, to figured out what problem is the culprit you will need to get your car diagnosed with the right tools. It’s also important to physically inspect your engine and other parts of your car to see what’s wrong. So, diagnose and fix things properly and don’t wait until things get even worse.

You definitely want to get this fixed as soon as you can. Because problems that are causing your car to shake can lead to other complications. For example, when your motor shakes in an unusual way, it’s possible that it could cause problems with your ignition and fuel timing. If you don’t get this issue repaired swiftly, then continuing to use the car is going to be problematic.

What Should You Do?

Now that you know that you’re experiencing some type of serious problem, you need to figure out what needs to be done.

1. Diagnose the Problem

I cannot stress it enough but, your best bet is going to be to take your car to an expert mechanic or your dealership. Experts are going to be able to determine exactly why your check engine light is on and why is your car shaking. They can hook a car up to their diagnostic tools to run a full scan. This is going to give them all of the necessary information to make a diagnosis. If you happen to have an OBD-II scanner, then you can do this by yourself at home.

2. Fix Things Properly

Now that you know the cause of the problem it is very important to fix things right. If your problem is faulty or broken car engine mounts, then getting those replaced is very important.

It’s also important to note that fixing this problem by yourself isn’t going to be easy. Especially, if you are not equipped with the right tools, this will be a pretty big job. Your local expert mechanics will be a better option to get things taken care of right. They will also be able to figure out if one of the other problems such as misfires, faulty spark plugs, or bad fuel pressure is to blame.

This is going to make a lot easier for you to get your car back in working order in a timely fashion. It’s a good idea to go this route, unless you happen to be a master mechanic.

In Conclusion

It should be a little easier to understand what to do now that you’ve checked into things. The easiest way to take care of this problem is likely going to be to take your car to the mechanic or to your dealership to get things checked by professionals. If you don’t want to go this route, then you’ll want to diagnose the specific issues that are wrong with your car and then move forward from there. Whatever you decide to do, it’s important to fix things before continuing to drive your car.

Your car shaking problems should be able to be solved by replacing the engine mounts or fixing other problems that might be potential causes. Once things are fine, you’ll be good to drive down the road again. You want to be able to feel confident that your car is perfectly safe. Never just keep driving your car when it’s shaking and the check engine light is flashing, as this is only going to put you in danger.
