Hello and welcome to JustAnswer!

There are many things that can cause a misfire. It could be an ignition system issue (most common) but it could also be an injector problem, an injector or coil driver, a localized vacuum leak causing a cylinder to run leaner than the rest, or it could be a cylinder sealing/valvetrain issue.

Have you checked for fault codes?
