Question:<\/strong> I experienced the symptoms of a misfire while I was driving my car yesterday, so I brought my car to the repair shop as soon as possible. How much will it cost to fix an engine misfire?<\/p>\n\n\n\n

Answer:<\/strong> Fixing an engine misfire can cost less than a hundred dollars, or it can cost thousands of dollars, depending on the vehicle you drive and what\u2019s causing the problem. Unfortunately, it\u2019s difficult to nail down a more accurate estimate without knowing the specifics of the issue.<\/p>\n\n\n\n

What is an engine misfire?<\/h2>\n\n\n\n

When your engine is working properly, the combustion chamber draws in the correct mixture of air and fuel. The mixture is then ignited by the spark plugs, which creates enough power to push down the cylinders that move the engine\u2019s crankshaft.<\/p>\n\n\n\n

If any part of that process fails, your engine will experience an interruption in power\u2014otherwise known as a misfire.<\/p>\n\n\n\n

To the driver, that might feel like decreased power or a jerking or vibrating feeling when accelerating. You might also hear a loud backfiring noise.<\/p>\n\n\n\n

Causes of an engine misfire<\/h2>\n\n\n\n

Here are some common reasons you might have a misfiring engine, along with the average cost to fix each:<\/p>\n\n\n\n

Bad spark plugs<\/h3>\n\n\n\n

If one of your spark plugs is worn out, it may not effectively ignite the air\/fuel mixture, so there won\u2019t be enough power to move the cylinder that powers the crankshaft.<\/p>\n\n\n\n

Replacing your spark plugs will likely cost somewhere between $80 and $320 if you have it done professionally. If you have a little mechanical experience, you can replace them yourself and save on labor costs.<\/p>\n\n\n\n

Failing ignition coil<\/h3>\n\n\n\n

If your spark plugs are in good shape, but they don\u2019t seem to be firing correctly, the problem could be with your ignition coil, the part that powers the spark plugs.<\/p>\n\n\n\n

Replacing ignition coils typically costs between $150 to $800 per coil. It’s more expensive in vehicles with more advanced ignition systems. Most vehicle engines have four (V4), six (V6), or eight (V8) cylinders, and you may have either one coil for each cylinder or one coil for every pair of cylinders.<\/p>\n\n\n\n

Improper air\/fuel mixture<\/h3>\n\n\n\n

Your engine needs a specific ratio of air and fuel for combustion to occur properly. A malfunctioning fuel system or air intake system can lead to the engine receiving too much air and not enough fuel\u2014which can cause engine misfires.<\/p>\n\n\n\n

Depending on the reason for a lean air\/fuel mixture, the fix could range from around $100 to repair a hose to more than $1,500 to replace your fuel pump.<\/p>\n\n\n\n

Worn timing belt or chain<\/h3>\n\n\n\n

As the name suggests, a car\u2019s timing belt or timing chain helps ensure all of your engine\u2019s components move when they should. If the belt or chain is worn or out of place, it could throw off that rhythm, which could lead to a misfire.<\/p>\n\n\n\n

Replacing your timing belt usually costs somewhere between $300 and $500. If your vehicle has a timing chain, it may cost as much as $2,000 to replace.<\/p>\n\n\n\n
