How do I know when I need new spark plugs for my car

My car has 144560 miles.
My car has an automatic transmission.

Hi There, Some common signs of failing spark plugs may be things like engine surging, poor fuel mileage, problems with engine starting or engine misfiring. I would recommend having a professional from YourMechanic come to your location to take a look at your vehicle.
