When to change spark plugs, 6 tell tale signs?
When a vehicle sucks in more air than usual in the combustion process it can cause the vehicle to jerk and then slow down or continually start and stop, which means the vehicles engine is working inefficiently. This is also known as engine hesitation and dangerous situation can arise if this occurs in traffic.
What can a spark plug tell you about your car?
What Your Spark Plugs Can Tell You: Spark plugs are the all-important device that delivers the necessary Spark to your engine, and when combined with the proper gas-air mixture, provide the necessary combustion to run your motor. And a spark plug’s condition can provide tell-tale signs about the condition of your engine.
Why do you need to change your spark plugs?

If spark plugs are not checked with regular services, cleaned or changed when necessary, they can cause problems to occur with the vehicle’s engine. Below are six signs for when to change your spark plugs: 1. Engine has a rough idle
What does a burnt spark plug look like?
If you see melted electrodes, blisters on the insulator, or any white deposits it is a sign of a burnt spark plug. It is simply running way too hot for its application, and in outdoor lawn equipment, this can be a result of using the wrong spark plug, incorrect gas/air mixture, or a loose spark plug.

How many spark plugs does a four cylinder car have?
Every cylinder of a vehicle has a spark plug so a four-cylinder car has four spark plugs, a six-cylinder has six plugs, and so on. When even one spark plug is bad or dirty, your vehicle’s performance will suffer.
Where does the Spark Go in double platinum spark plugs?
Double platinum spark plugs were designed for “waste spark” DIS. In a waste spark system, the spark jumps from the center electrode to the side electrode for the cylinder that’s on the compression stroke. To return the electrical pulse back to the ignition coil pack, the spark jumps backwards (side-to-center) on the partner cylinder.

It is simply running way too hot for its application, and in outdoor lawn equipment, this can be a result of using the wrong spark plug, incorrect gas/air mixture, or a loose spark plug.
Can a bad spark plug cause an ignition coil to fail?
Most ignition coils are durable components, but they are neither indestructible nor designed to last forever. Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely.
Where is the ignition coil located on a car?
Older vehicles have a distributor, ignition coil, and spark plug wires. Most vehicles made after the late 1990s typically have a small ignition coil that sits directly on top of each spark plug, which is known as coil-on-plug (COP) design. Regardless, the functionality is the same. When you start your engine, current flows to the ignition coil.
Can a worn out spark plug cause a faulty ignition coil?
Worn out and faulty spark plugs can also put excessive pressure on the ignition coil, causing damage to them. You should check the ignition coil regularly to ensure they are in good working condition. A faulty ignition coil will not provide enough power to the spark plugs to start the engine.
What happens when you dont change your spark plugs?
This continuous ignition is what keeps your car moving on the road. If spark plugs are not checked with regular services, cleaned or changed when necessary, they can cause problems to occur with the vehicle’s engine. Below are six signs for when to change your spark plugs:
When do ignition coils need to be replaced?
If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils. Nevertheless, on most vehicles can go 80,000 to 100,000 miles before requiring an ignition coil replacement.

What happens when you don’t change spark plugs?
The sound the engine gives off is constant and smooth but if your spark plugs aren’t performing as they should, your engine will produce a rough and jittery sound while producing larger vibrations through the car. Not having this checked can lead to costly damage being done.
Why does my Mercedes not start when I charge the battery?
This Mercedes-Benz is not starting because of a low battery. In this case, what you need to do is trickle charge your battery using any of these 12 volt battery trickle chargers. If you need help read this article on How to charge a Mercedes-Benz the right way. Mercedes won’t start, and it’s not the battery.
Why is my Mercedes Benz starter not working?
Often times, when the starter is defective or seizes up it will blow out the fuse that protect the starter circuit. Another thing that you can try is to hit the starter with a rubber hammer a couple of times. Depending what kind of starter problems you have, the starter may work a few more times.
Where do I go to change my spark plugs?
All Repco Authorised Service centres make sure to test all vital components like spark plugs in their safety checks. Contact your nearest Repco Authorised Service centre today to have your car back on the road and working efficiently. Do you know any other signs of when to change spark plugs?
What happens when your spark plugs are not working?
Your engine idles when it is a stationary and in this position the engine normally produces around 1000rpm. The sound the engine gives off is constant and smooth but if your spark plugs aren’t performing as they should, your engine will produce a rough and jittery sound while producing larger vibrations through the car.
How can I tell if my engine wires are arcing?
Sounds like your wires could be arcing. First, with the engine off, check the wires for cracks or see if they look all dried out. (Bending them gently in a loop will make the cracks very visible.) If that doesn’t show anything, then pop the hood in the dark (night)and watch for sparks to jump around by the plug wires.

Can you drive a car with a missing spark plug?
But if it is a multiple cylinder engine, then your car can still drive with a missing plug, however, this will cause instabilities to the crank. So finally if your car is a diesel engine car, then with a big yes, you can drive the car with a missing spark plug and that is because diesel engine cars are built to run without a spark plug.
Can a lack of Spark cause an engine to stall?
Just like the lack of spark in the spark plugs can cause an engine to stall, it can also prevent it from starting again. This is especially common when there is oil leaking onto the tip of the plugs.
What causes the spark plug to foul when the engine is running?
When the engine is running, the ceramic shell that surrounds the center electrode gets hot and helps to burn off any fuel or oil ash deposits that might otherwise foul the spark plug. The “heat range” of the spark plug determines its operating temperature and its built-in fouling resistance.
What are the signs of a faulty spark plug?
Common signs of faulty spark plugs include slow acceleration, loss of power, poor fuel economy, engine misfires, and difficulty starting the car.
Can a spark plug be pregapped for an engine?
Most spark plugs are pregapped, but the gap may not be correct for your engine application. If you can’t avoid a lot of idling or short trip driving, refer to the spark plug supplier’s catalog for a spark plug that is one heat range HOTTER than the standard spark plugs specified for your engine.
Why are spark plugs good for highway driving?
The spark plugs that are specified for your engine by the spark plug manufacturer should be correct for your vehicle application. Full throttle acceleration and highway driving is good for spark plugs because it generates heat that helps keep the spark plugs clean.
