What Are the Signs of Bad Spark Plugs?


Your spark plugs may be small, but they have a major responsibility. They are devices that carry electrical energy to the ignition coil so your engine can stay on. In other words, your engine would not run without proper spark plugs. Regular inspections and replacements of spark plugs ensure you’re never put in an inconvenient situation. The following signs indicate your car is due for a spark plug replacement:

Stalling or Misfiring Engine

If any of the wiring or connection points relating to your spark plugs are damaged or loose, your engine will have inconsistent responses and stutter. Therefore, car stalling and misfiring are frequent signs that indicate worn spark plugs.

Lowered Fuel Economy

When your spark plugs are no longer effective, they can cause your engine to work harder than necessary. Nevertheless, it messes with the air-to-fuel ratio too. If your fuel mileage has dropped, please come by for a spark plug inspection and tune-up soon.

Sluggish Acceleration

If you press your foot on the gas pedal, and your car takes a while to trigger a response, you probably have worn spark plugs. Please come by City Garage for a check-up.

Check Engine Light Is On

Faulty spark plugs will likely cause stalling, which will trigger your check engine light to flicker on. Bad spark plugs are a common diagnosis for check engine lights. At City Garage, we will use a proper scan tool to verify the problem.

If you suspect you need new spark plugs for your vehicle, please turn to the professional team at City Garage today. We provide the best tune-up services in the city,
