Why Are Misfires So Hard To Diagnose?

Even if you're not a car enthusiast, you can probably recognize a misfire when one happens to you. These annoying problems tend to feel like stuttering or hesitation, either at idle or while accelerating. Depending on the severity of the problem, you might feel your engine stumbling or vibrating or even notice that the car wants to stall. In technical terms, a misfire occurs when one or more engine cylinders fail to produce complete production.
