Auto Service Kingston can replace your faulty spark plugs when they need it. Generally, in newer automobiles, this is every 160,000 kilometres. If you drive an older automobile, you need to have the plugs changed every 48,000 kilometres. We are going to list the signs of faulty spark plugs below so you know what to look for in your automobile. Don’t worry. We can change out the plugs.
Hard Starts
Vehicle engines have a difficult time starting when the spark plugs are bad. The reason why is that the engine cannot produce combustion until the air and fuel in each cylinder are ignited with the spark. If the spark plugs are not all firing correctly and in the correct order, you will be hard-pressed to get your engine started.
Rough Idling
If you are able to start the engine, it will idle roughly and may even stall immediately. It may take several times to get the engine started to the point that it will keep running. Even though the engine is running, it may still idle roughly if you need to replace the spark plugs.
Misfires/Stalls
In fact, the engine will also misfire and stall. Again, the engine cannot produce combustion if the spark plugs do not provide continual sparks to ignite the air and fuel. Consequently, one or more cylinders may not fire, and this is what causes the engine to misfire. It will also stall frequently.
Surging/Bucking
You may also start to have problems with your vehicle’s engine surging or bucking. This can be an indication that you’ve got multiple firings in the cylinders. This can cause the engine to pick up speed by itself unexpectedly. Naturally, this can be alarming when you are driving your automobile.
Poor Economy
In addition, your vehicle will suffer from poor fuel economy because when the spark plugs fire multiple times, they burn excess fuel. Consequently, you will need to have the spark plugs replaced in order to restore your fuel efficiency. This is because replacing the plugs will restore your engine’s efficiency.
Acceleration Lag
One final problem that occurs when the spark plugs are worn out is acceleration lag. Again, this can be attributed to a problem with the firing in the cylinders. If the air and fuel are not fired, your engine will lose power and fail to respond to the accelerator when you press it down.
