A spark plug is an electrical part installed in a car engine, which, due to an electrical discharge and a spark between the electrodes, causes the combustible mixture to ignite, which provides the engine with the necessary energy to operate.
Stable engine operation, fuel consumption and overall vehicle performance depend on the operation of spark plugs. Depending on the type of engine, operating conditions and manufacturer's requirements, different types of spark plugs are used, which have different designs and operating parameters.
The main symptoms of a broken spark plug
If you find any of these symptoms in your car, we recommend that you contact a car service for diagnostics and identification of a non-functioning spark plug. In this case, it is possible to replace only one problematic spark plug.
When replacing one spark plug, it is necessary that the replaced spark plug matches the spark plugs that are in other cylinders (type, design, manufacturer).
Basic rules for replacing a spark plug
Depending on the engine and the manufacturer’s recommendations, to ensure high-quality engine operation, it is necessary to regularly replace a complete set of spark plugs.
Don't throw away old spark plugs.
By the appearance of the spark plug, you can determine the condition of your car's engine:
In any case, replace the faulty spark plug.
If a problem with the spark plugs occurs while driving, in an older car, where access to the spark plug is quite easy, you can replace it.
On new cars, replacing a spark plug is a rather complicated process; you will need certain knowledge, a special tool for removing protection elements, ignition coils, and here we recommend contacting an emergency service to tow the car to a car service center. In addition, a certified car service center will carry out additional diagnostics, check engine error codes and test other vehicle systems, this is very important since in most cases the cause of spark plug failure is a vehicle malfunction.
It commonly shakes when stopped because of loose or damaged motor mounts. However, it can also be fuel flow problems that are overstressing the engine, such as carbon deposits, faulty fuel injectors, leaking intake valves, or damaged spark plugs.
If you're experiencing your car trembling when it comes to a halt, taking action is essential. This occurrence may be a symptom of an underlying problem that warrants your attention. While it may appear minor, the shaking can affect your vehicle's handling and performance, threatening road safety.
To prevent further damage and expensive repairs, it's vital to act promptly and consider having a vehicle health inspection. By doing so, you can rest assured that your car will be safe to drive and won't pose any danger to yourself or others on the road.
The lawn mower sound is typically due to a crack in the combustion system. A vehicle's combustion system features many components, such as cylinders, spark plugs, and exhaust, which are all susceptible to damage. These are the most common issues involving these parts:
The engine is sputtering because of a faulty fuel pump or mechanical failure, causing the unmeasured fuel pressure to create sputters. But it can also be because of worn spark plugs, faulty sensors, or a damaged ignition coil.
While the unsettling feeling of your engine sputtering might not have to do with engine problems, it indicates something wrong with your car that you shouldn't ignore.
A sputtering engine relates to how your car intakes and burns fuel. If it doesn't burn fuel cleanly and efficiently, your fuel economy suffers, risking expensive repairs to your engine, exhaust system, and catalytic converter. Plus, your car creates excess emissions that damage the environment.
In addition, some issues related to engine sputtering can prevent your car from starting, leaving you stranded and in a dangerous predicament.
The good news is that engine sputtering is easy to recognize and more straightforward to identify when the "check engine" light comes on. If you take your car to a technician before the problem damages the engine, the fix could be as simple as replacing the spark plugs or cleaning the fuel pump. Unfortunately, putting the issue on hold can severely impact your car's fuel efficiency.
