Of course, poor spark plugs can lead to incomplete combustion and it might cause your vehicle to use more fuel than expected. If you notice a lowering in mileage, you must take proper action to check the spark plugs.

Rough Idling:

A shaky or vibrating engine at idle is a classic sign of spark plug issues. When spark plugs misfire or fail to ignite properly, it can result in an uneven engine idle. At that time, you should go for a quick replacement.

Engine Misfires:

Generally, engine misfires occur when the spark plugs don’t ignite the air-fuel mixture correctly. This leads to a loss of power and it can feel like a sudden jerking or stumbling while driving. To get rid of this problem, make sure to keep proper maintenance breaks.

Hard Starting:

Difficulty starting the engine, especially in cold weather is another sign of bad spark plugs. Due to this reason, your spark plugs may struggle to produce the required strong spark for ignition.

Lack of Power:

If you experience a noticeable loss of power during acceleration, it’s often because of spark plug problems. The engine may feel sluggish and struggle to respond to throttle input.

Check Engine Light (CEL):

In many modern vehicles, a misfiring spark plug can trigger the check engine light on your dashboard. If the CEL comes on, it is better to check your vehicle’s diagnostics and take necessary actions. Do not be late in this case and follow the proper suggestions.

Rough Engine Sound:

A poorly firing spark plug can also result in unusual engine noises. You may hear popping or backfiring sounds, indicating ignition problems.

Increased Emissions:

Bad spark plugs indicate higher emissions, and it contribute to environmental pollution. Regular emission tests can detect this issue.

Ultimately, paying attention to these symptoms can help you identify and address bad spark plugs promptly. Regular maintenance, including spark plug inspection and replacement, can keep your engine running smoothly and efficiently.

How Do I Check If A Spark Plug Is Good?

Every driver wants to run their vehicle with a good engine and spark plugs. But most of them don’t know how to identify a Spark Plus is good. Let’s find out the ways to detect below:

Before you start the procedure, you must bring the necessary tools like:

  • A spark plug socket wrench or a spark plug gap tool.
  • Safety glasses and gloves (for protection).

Now, let’s start the process:

Step 1: Safety First

Before you begin, make sure your engine is cool to the touch to avoid burns. Put on safety glasses and gloves for protection.

Step 2: Locate the Spark Plugs

Find the spark plugs in your engine. They are connected to thick wires leading to the ignition coil. In most engines, you’ll find them along the top or sides of the engine block.

Step 3: Remove the Spark Plug

Use the spark plug socket wrench to carefully remove one spark plug at a time. Gently, avoid damaging the threads.

Step 4: Inspect the Spark Plug

Once removed, examine the spark plug closely. Here’s what to look for:

Normal: A good spark plug should have a light tan or grayish-brown color on the insulator and electrodes. This indicates a healthy combustion process.

Worn: If the insulator is white or blistered, or if there’s excessive carbon buildup or oil deposits, it’s a sign of a worn spark plug.

Fouled: A wet, black, or heavy carbon deposit on the spark plug indicates fouling, often caused by a rich fuel mixture, oil leaks, or excessive idling.

Damaged: Any physical damage, like a cracked porcelain insulator, bent electrode, or broken ceramic, means it’s time for a replacement.

Step 5: Measure the Spark Plug Gap

Use a spark plug gap tool to measure the gap between the center electrode and the ground electrode. Refer to your vehicle’s manual for the correct gap measurement. If it’s too wide or too narrow, adjust it accordingly.

Step 6: Replace or Clean

If the spark plug is worn, fouled, or damaged, it’s best to replace it. If it looks good and the gap is correct, you can clean it with a spark plug cleaner or a wire brush before reinstallation.

Step 7: Reinstall the Spark Plug

Carefully thread the spark plug back into the socket hole by hand to avoid cross-threading. Then, use the spark plug socket wrench to tighten it snugly, but do not overtighten.

Step 8: Repeat for Other Spark Plugs

Repeat this process for all spark plugs in your engine

It is better to run this process periodically after every 20,000 to 30,000 miles. Thus, you can find out the real result clearly. Indeed, replacing any worn or damaged plugs ensures your engine runs smoothly.

If you do not how often should you change your spark plugs, the next topic is waiting for you.

How Often Should I Change My Spark Plugs?
