6 Symptoms of Faulty or Damaged Spark Plugs
would be unable to ignite in the combustion chamber without the presence of a
spark. For many years, spark plugs have been an integral part of the internal
combustion engine. Spark plugs are designed to provide an electrical signal
from the ignition coil at a specified moment to ignite the air-fuel combination
inside the combustion chamber.
car requires a unique spark plug manufactured of specified materials and
installed with a specific spark plug gap established by a professional during
installation. Good spark plugs will effectively burn fuel, but poor or faulty
spark plugs will cause the engine to not start at all.
your car's MOT
status and schedule an appointment with a mechanic if you're
experiencing slow acceleration, lack of power, poor fuel efficiency, engine
misfires, or trouble starting your car. These are all signs that your spark
plugs are malfunctioning.
plugs, like engine oil, fuel filters, and air filters, need to be serviced
and maintained on a regular basis to keep your engine operating smoothly. Spark
plugs must be changed every 30,000 to 50,000 miles in most cars.
modern vehicles on the other hand, feature improved ignition systems that
theoretically eliminate the need for spark plug replacement. There are times
when a spark plug wears out or exhibits indications of failure, regardless of
any warranties or promises made by the car manufacturer.
frequent signs of worn-out or clogged spark plugs that need to be changed by
a car mechanic as soon as possible are listed below:
1. Slow acceleration - In
most vehicles, a malfunction with the ignition system is the most prevalent
reason of poor acceleration. The issue might be a broken sensor in today's
sophisticated engines, which have several sensors that inform the onboard
computer and ignition system when to send electric pulses to fire the spark
plug. Occasionally, though, the problem is as simple as a worn-out spark plug.The
components of a spark plug work together to create a hot enough spark to ignite
the air-fuel combination. When such materials wear out, the spark plug's
effectiveness is diminished, which can result in a considerable loss of vehicle
acceleration. It's conceivable that your next MOT may fail the emissions test.
As a result, it's a good idea to check MOT status of
your car and get the spark plugs changed ahead of time.A broken spark plug
that must be replaced might be the cause of your car's sluggishness or
inability to accelerate as rapidly as it once did. However, you should see a
professional to investigate this problem because it might be caused by a
variety of other reasons such as blocked or filthy fuel injectors, or problems
with oxygen sensors.
2. Reduced Fuel Economy
- In the combustion cycle, a fully functional spark plug aids in the efficient
burning of fuel. When this happens, your car's fuel efficiency will be better
than average. When the spark plug isn't operating properly, it's usually
because the spacing between the electrodes is too tight or too far apart.
Instead,then replacing the spark plug totally, many mechanics will remove it,
inspect it, and adjust the gap to factory values. A worn-out spark plug might
be to blame for an increase in fuel usage in your car.
3. Misfiring Engine - When
the engine misfires, it's usually due to a problem with the ignition system.
It's frequently caused to a sensor failure in newer autos. However, it might
also be caused by a broken spark plug wire or the spark plug tip that attaches
to the wire. Intermittent stuttering or sputtering noises from the engine
indicate an engine misfire. If the engine continues to misfire, exhaust
emissions will rise, engine power will fall, and fuel efficiency will suffer.
Was this one of the reasons of a failed MOT test on a MOT history check
of your car?
4. Engine Surging or
Hesitation - While accelerating, you may notice the engine hesitating. The
engine is not reacting appropriately to the driver in this scenario. It may
have a brief burst of power before slowing down. In its combustion process, the
engine is drawing in more air than it should, resulting in a delay in power
delivery. A spark plug issue might be indicated by the combination of
reluctance and surging.
5. Rough Idle - When your
engine is idling, it may sound rough due to a faulty spark plug. Your car will
tremble because of the all-encompassing, frenetic sound. It might be an
indication of a spark plug problem if a cylinder misfires only when the engine
is running. This can also cause your dashboard's check engine light to
illuminate. If you check MOT
history and find that your car failed a prior MOT because the
engine management light was on, a simple maintenance like spark plug
replacement might have been the cause.
Difficulties - If you're experiencing trouble starting your vehicle, it
might be because your spark plugs are worn out. The engine's ignition system,
as previously said, is made up of numerous separate components that must work
together to function properly. As soon as you discover problems starting your
car, you should contact a skilled mechanic.
Whatever the problem is, you may require new spark
plugs when they wear out. Taking care of your spark plugs on a regular basis
will help your engine last for thousands of miles.
