Misses generally are caused by failing ignition components like spark plugs, ignition coils, ignition wires, etc. But, every once in a while a component like an injector, or a valve spring can fail and cause a misfire similar to an ignition component. Specialized tools like scanners, noid lights, and coil on plug spark testers are necessary for a proper diagnosis of the engine misfiring. A mechanic such as one from YourMechanic should be able to help you determine the cause of the misfire and get you fired up and back on the road.
