The plugs, wires and various other components deliver the spark your vehicle needs to get the engine to start. Those wires send electricity from your distributor into the plugs, thus causing them to spark and ignite the fuel in your vehicle. This powers the pistons and gets your vehicle going. Over the course of time, all of the unburnt oil and gases end up building up on your spark plugs, causing them to struggle to start and move. To help you better understand the signs of spark plug failure, be on the lookout for one of the following signs.
Your vehicle won't start first thing in the morning.
If the plugs and wires are dirty or damaged, it will become almost impossible for them to get the spark needed to get your engine going. It can cause your battery life to be depleted as well. Vehicles that don't start well in the morning often have something going on with the plugs and wires. You want to have a mechanic look into this for you so you can get them replaced as quickly as possible.
The engine hesitates or surges.
Hesitation and surges are often signs that your vehicle's engine aren't working the way it should. This can become extremely dangerous if you are stuck sitting in traffic for extended periods of time. Your vehicle could end up lunging forward and causing an accident. The same holds true with hesitating. The light might turn and you need to go, but your vehicle hesitates and the person ends up hitting into you causing all sorts of problems. Anytime your engine doesn't respond when you push on the gas, you need to have it inspected for possible issues that need to be corrected.
Dirty plugs and wires can cause your vehicle not to get the right amount of spark. Too much spark causes it to surge forward because it thinks you are pushing down on the gas pedal. Not enough spark causes your vehicle to want to stall because it doesn't recognize that the engine is still running. Your vehicle needs the right mixture to run properly otherwise it will end up shutting down or revving forward.
If you are dealing with one of the above, you need to take your vehicle in to a licensed mechanic and see about having your spark plugs replaced. This will save you a lot of hassles and headaches down the line.
