Q: Q: The car is misfiring.

asked by on

My question is, do I need to replace the coil pack if I already changed the spark plug?

My car has 273290 miles.
My car has an automatic transmission.

Hi, thanks for writing in. There are many things that could cause a misfire, such as faulty spark plugs, a bad coil pack, bad injectors, a faulty crank position sensor or something else. I would recommend having an expert from Your Mechanic come to your home to diagnose the misfire to avoid repairing and/or replacing unnecessary parts.
