Q: Car misfires; loud engine noise

asked by on

My car misfires, and the engine makes a loud noise.

If your vehicle is misfiring, and making lot’s of noises, there is probably some sort of engine performance related problems. Symptoms like these can be caused by the need for a tune up, to a problem with one of the engine’s sensors. I would recommend having the vehicle looked over by a professional technician, such as one from YourMechanic, in order to determine the cause of the engine misfire.
