Buyer’s Guide

With all this new information, you should be able to choose a great option that works for the Tahoe that you have. Whether you have a 1st, 2nd, 3rd, or 4th generation Tahoe, you can find an option on this list that will fit your model.

However, even with all this new information, you may still some questions about sparks plugs that you would like answered before you make your final purchase decision.

So, in order to get you the answers you need, we have compiled a list of the most common questions and searched for the most in-depth answers possible. So, here are some of the most frequently asked questions about spark plugs.

What do spark plugs do?

Spark plugs emit a spark of electricity that cross a small gap that creates the ignition for the combustion needed to start the car.

Spark plugs emit a spark of electricity

By putting the engine’s pistons in motion, the car will power up, stay on, and produce a smoother burn of the compressed air-fuel mixture.

What are the symptoms of bad spark plugs?

The first sign of a bad spark plug is having trouble starting the vehicle. This is a sign that your spark plugs are not sparking the electricity needed for ignition combustion, and may need to be replaced.

However, there are multiple components that work together to start your vehicle, so it is recommended to take your car to a mechanic to help diagnose the problem correctly.

The second sign is the feeling of a slowing of acceleration. The spark plugs have to be able to produce a big enough spark to help start the engine and keep it running smoothly, but if the plug is worn out, then the acceleration won’t be consistent.

This could mean that you need to switch out your spark plugs.

Another sign of bad spark plug is your vehicle getting bad fuel economy. When spark plugs are working properly, they help to burn fuel efficiently in the combustion cycle. But when the plug is worn out, then that process is compromised.

It should be noted that although a bad plug could cause this, it could also be caused by an improper gap between the electrodes. If that is the case, then they may just need to be adjusted and not replaced.

The last, and perhaps the biggest, sign of a bad spark plug is the misfiring of the engine. This could cause sputtering or jerking of the engine that you may feel when you are driving and could point to you needing to replace your spark plugs.

If you don’t replace the bad spark plugs, then the engine will continue to misfire, the engine exhaust will increase, and the fuel economy will suffer.

Do spark plugs need to have a gap?

Yes, in order to work properly, spark plugs need to have an exact distance between the center and side electrodes. You will need a feeler gauge to gap your spark plugs properly so that they work efficiently.

What is the proper spark plug gap?

The size of the gap depends on a number of factors that pertain to the type of vehicle and engine that you have. When you buy spark plugs, the information that comes with them will tell you what the exact gap size should be for your vehicle.

However, the total gap size should never exceed .055 inches, unless it is pre-set by the manufacturer.

What will happen to the engine if the spark plug gap is wrong?

If the spark plug gap is not properly spaced, the efficiency of the engine will suffer. The ignition spark will lose its strength and cause the engine to hesitate.

It may also cause the engine to misfire, the fuel efficiency to suffer, and can cause the engine to be difficult to start.

What does a bad spark plug look like?

A bad spark plug will become covered in an oil-like substance that is blistered from running too hot. You will be able to feel when spark plugs are going bad, likely far before you see it, because of the loss of performance that you will see in your vehicle.

Reduced gas mileage and issues with ignition can be signs that you should check your spark plugs. If you check them and they have the substance mentioned earlier, then you know that it is time to replace them.
