check your car's MOT status and book in with a mechanic for repairs. These are all symptoms that your spark plugs aren't working properly.
Fuel 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.
Each 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.
Check 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.
Spark 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.
Some 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.
