My car’s engine keeps misfiring and I suspect that the fuel injectors are clogged. I’ve seen some fuel injector cleaners online—will my engine still misfire after using a fuel injector cleaner?

Sorry to hear that you’re dealing with that! Fortunately, you’re right about clogged fuel injectors being a symptom of a misfiring engine.
If used correctly, though, a fuel injector cleaner should remedy the problem and stop your engine from misfiring.
If you suspect that the injectors are still clogged after using a cleaner, you’ll need to head to an auto mechanic to have them diagnose the issue.
Since you’re thinking about your vehicle’s maintenance, now may be a good time to double-check your
car insurance
to see if it still meets your needs.
