Frequently asked questions
What does a misfire feel like?
Usually a stumble, jerk, or loss of power, sometimes with a flashing check engine light and a rough idle.
Can I keep driving with a misfire?
Brief driving is okay, but a steady misfire dumps raw fuel into the exhaust and can ruin the catalytic converter — get it diagnosed soon.
