Spark plugs are responsible for delivering the spark that ignites the air-fuel mixture in your engine cylinders. They are small, but they play a role in how effectively and efficiently your engine operates. Here are symptoms of bad spark plugs:
A failed spark plug can cause a misfire because it won't send electricity through to ignite the fuel mixture. A bad ignition coil or plug wire will also cause your engine to misfire.
Another cause of a misfire is the fuel injector or fuel pump problem. A faulty fuel injector will cause the engine to run lean, while if you have a faulty fuel pump, you might experience too much pressure in the cylinders. It could lead to overheating or even combustion problems.
Poor Fuel Economy
Poor fuel economy is a common problem caused by many factors, including a bad spark plug, poor fuel filter, or even a faulty fuel pump. Although these symptoms are not always directly related to the spark plugs, they can all point to crucial problems with the engine performance.
This is a common symptom of a bad spark plug. Other issues can cause engine surging like a bad fuel pump, injector, or low gas pressure due to clogged or broken fuel lines. If you're experiencing any of these symptoms, it's crucial to check the engine belts and hoses for leaks before you replace your spark plugs.
Lack of Power
If your car is not performing at its peak, it might be time for a spark plug change. A bad or failing spark plug can cause your engine to run poorly and struggle to reach its maximum horsepower. A working spark plug will help your engine run at its highest level of efficiency.
One of the most common symptoms of a bad or failing spark plug is hard starting. It means that your car is having trouble turning over. If you're in a cold area, the engine may take longer to start because it needs to warm up before firing up.
