    A misfire fault needs to be addressed right away. You can cause damage to the catalytic converter if you continue to drive this way. It would be best to drop in for diagnostics and repair as soon as possible, this way you may prevent a more expensive repair. If your check engine light is flashing damage may occur and it's best not to drive it at all.
