Clear Signs That Your Spark Plugs Need To Be Replaced

A spark plug is a electrical device used in an internal combustion engine that is, an engine that derives its power via exploding gases inside a combustion chamber to ignite the air-fuel mixture.It contains an artificial bolt of lightning within the combustion chamber (cylinder head) of the engine. The electrical power means voltage is transmitted to spark plug in order to create a spark and to “light the fire” within the controlled chaos of the combustion chamber. Here, the voltage at the spark plug can be anywhere from 20,000 to more than 100,000 volts.Spark plugs have an insulated center electrode which is connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder.

This continuous ignition is what keeps your car moving on the road.Over time unburnt gases and oil create a buildup of carbon residue on your car’s spark plugs, which can lessen the performance of your vehicle’s engine and make a cold start more difficult.If you're having trouble starting your car, it may be due problems with your spark plugs or ignition wires. So spark plugs are need to be checked with regular services, cleaned or changed when necessary, they can cause problems to occur with the vehicle’s engine.

Below are six signs for when to change your spark plugs:

The engine idles roughly (you can hear it clearly ) :-
The sound of your car’s engine should be constant and smooth. But if your spark plugs aren’t performing as they should, then your engine will make a rattling, pinging, or knock-like noise.While producing larger vibrations through the car. Not having this checked can lead to costly damage being done.

High fuel consumption :-

Having spark plugs that function properly help keep the emissions coming from your vehicle at a minimum.But in case of Worn out spark plugs can increase your vehicle’s fuel consumption because they won’t effectively burn the fuel that goes into the engine, meaning you’ll be shelling out more money on fill-ups.Your vehicles fuel economy can decrease by up to 30% due to incomplete combustion. 

If you noticed you’re having to fill up more often than usual it can be caused by deteriorating spark plugs. To get back to your vehicle’s optimum level of fuel consumption all you’ll need to do is have your spark plugs changed.

Trouble starting your car :-
Many people put their car not starting down to being out of fuel or having a flat battery. In-fact one of the possible reason for starting trouble is Dirty spark plugs and damaged wires make it difficult or impossible to deliver the spark needed to start the engine.They can even drain power from your battery. If your spark plugs don’t produce the spark needed to get the vehicle moving, then you’re going nowhere. It is also possible that faulty spark plugs are causing your battery to drain. If so you need to have your battery and spark plugs changed as soon as possible.

Lack of Acceleration :-
You’re probably pretty familiar with how your vehicle handles and drives.If your vehicle is accelerating poorly it is fairly easy to tell. It feels as if the vehicle doesn’t want to respond when you put your foot down, or it does but not instantly as you’ve become accustomed to. It can also feel as if your vehicle is trying really hard to pull itself along. This ‘sluggishness’ can be easily fixed by having the vehicle serviced with a spark plug change.

Engine Misfire :-
Engine misfire means that the vehicle is not functioning as well as it should because one or more of its spark plugs aren’t firing properly. This could lead to a reduction in fuel economy, reduced engine power, or increased exhaust emissions.It can be easily recognizable when an engine misfires.When your engine misfires it causes the vehicle to halt for a fraction of a second and then continues it’s usual movement. This means the vehicle isn’t functioning as smoothly as it should because one or more cylinders aren’t firing properly, which can also lead to higher amounts of emissions.

Engine surge or hesitation :-
Power surges and hesitation are signs your car’s engine is working inefficiently.When a vehicle sucks in more air than usual in the combustion process it can cause the vehicle to jerk and then slow down or continually start and stop, which means the vehicles engine is working inefficiently. It can be quite dangerous if they occur while you are in traffic. If you experience this, have your vehicle checked by a professional mechanic right away.
