Continuing to drive on worn out or damaged spark plugs can ultimately cause engine damage, so don’t put it off.
The ignition coils and spark plugs are what actually cause the ignition in your engine.

It could also be due to poor connections, damaged battery terminals, or a bad or dead battery. Sometimes, this could even be due to the starter, with the control terminal becoming corroded.

Overheating Damage: Overheating spark plugs can cause the electrode to wear faster. Pre-ignition from an improperly timed engine can cause this, as can an incorrect air to fuel ratio. Oil Contamination: If oil seeps onto the spark plug, it will foul the tip.
Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor if you do it yourself. In most cases it’s a simple job that will help to maintain peak performance and the highest possible gas mileage.
When the ignition switch is worn down, there can be a loss of power to the engine because of vibration like hitting a rough patch of road. This loss of power causes the engine of the car to die while driving. Something is wrong with the fuel pump.
The first is the oxygen sensor, which is located in the exhaust manifold. … If either of these sensors is relaying incorrect information.
