In this way, the experts recommend that we should not drive having a misfiring cylinder. Okay then, you may ask,  what are the causes of a misfiring cylinder?  

The major causes of the problem are: 

  • Bad spark plugs 
  • Imbalanced air.  
  • Fuel mixture.  

Understanding The Risk Of Running With A Misfiring Cylinder 

As you know, a car cylinder is one of the most necessary factors of your car engine. And, the proper quantity of combustion is a must for providing the essential power to the car to run at a high speed. Depending on your car’s engine, it might be about 12 cylinders within it. Once any of the cylinders misfire, then it can affect the whole system. 

Driving with a misfiring cylinder  

As said earlier, riding with a misfiring cylinder can awfully affect the vehicle. Then the question may arise, how long can you drive with a misfiring cylinder?  

Having more of your cylinders in poor condition, it’s not wise at all to drive far. Even, if you have only one misfiring cylinder, yet you can drive slightly more. But it is not wise to drive for a long distance, cause it may result in higher damage in your car. 

That is to say, it can cause a crucial power loss in your vehicle. That means, when a car is having four cylinders and all are in good condition, then it should run with 100% power. When any one of the cylinders is damaged, after this the car’s power can drop by 25%.

How to Fix Misfiring Cylinder

Below the steps and procedures, by which you can diagnose and fix this problem.  

Way 1: Pull Your Trouble Codes 

The first thing you need to do is to pull the trouble codes. Many of the mechanics include code readers.  In general, you can pull the codes for free by them. 

Also, you will be able to buy the trouble code readers at a reasonable price. Here are my recommended code reader from Amazon. 

Way 2: See and Check the Codes

If you perform with a proper code reader, you will be able to know what your trouble code means. However, using the cheaper code readers, they will show you only a numerical code. Then, check-in Google to understand which code do you deal with. Following are the traditional codes for engine misfiring:  

  • P0300—Random misfire 
  • P0301, P0302, P0303, P0304—Various cylinder misfires 
  • P071—Air/Fuel Mixture lean 

By knowing about the trouble codes, you will be able to understand, what should be your next focusing items. 

Way 3: Test the Ignition  

Keep in mind that, in most cases, an engine misfires happen for the ignition problem. Then, while the car is old enough and has a distributor, make an inspection on it first. 

To replace your distributor cap, you don’t need to cost that much.  

While having a modern car with ignition coils, you will be able to detect a misfiring cylinder simply. Turn on the engine and then try to listen to how it whistles. After that, of your engine.  

Start again the engine.  

Now, you will listen to a unique variation in its sound. Provided that, there is no difference in sound. Then, there are misfiring cylinders.  

If you get a dead cylinder, then again use the ignition with a different cylinder. Meanwhile, perform this test again. If this happens, then your ignition is effecting the misfire. You should replace the ignition.  

Moreover, there may be problems with spark plugs. Just switch the spark plugs in between two cylinders. If there are some issues, all you have to do is just replace the spark plugs.   

Way 4: Test whether there are Intake Vacuum Leaks

This is an easy system. At first, begin by opening the engine. After that, pull a can of starter fluid. 

Next, spread it around the intake manifold gasket. While you get a leak, you can listen to the engine’s rev.  

If you can’t do it properly, then go for a car mechanic.   

Way 5: Test the Compression  

In this phase, you will need a tool. Do you have this kit? If you do not, take one as per your requirements from Amazon. 

If you ask me to suggest, I would recommend using the Innova 3612  from Amazon. Check it in a while. 

At first, remove the spark plug in your dead cylinder. Then, plop the sock from the compression tester into the spark plug gap. After that, open the ignition source as the motor can’t really fire at the time of performing this test. Now, you have to put the key in the ignition for 5 seconds. See what’s the pressure reading in it. After that, keep some motor oil into the spark plug hole. Then again, insert the compression tool. Plus, handle your ignition once again. Record again. 

Again, replay aforesaid steps with different cylinders.  

Way 6: Test Fuel Delivery 

Once it’s about fuel-related misfires. If there’s a fuel pressure case, then you should test the fuel regulator. Ensure that there is nothing clogging up your fuel filter(s). Overall, ensure that the fuel pump is operating appropriately.  

Nonetheless, while there are issues with the cylinders for the aforementioned reason, then there may be a bad injector. Firstly, ensure there is the power to the injector. Turning on the ignition, Perform the process with a voltmeter.  

When you have power to your injector, do it just as you did for your ignition coils and spark plugs. Shift your injector with a different cylinder. Check whether there is a misfire in your new cylinder, or not. If there is a bad injector, then just replace the injector.
