Welcome to just answer, thanks for posting your question

I would not recommend driving it for more than about 200 miles since the misfire can cause catalytic converter problems, if the check engine light starts to blink it means the converter is overheating, power demand on the engine will increase the risk of the converter overheating as will high speed driving, try to keep this within check and avaoid hard acceleration, going up hills, mountain passes etc. The misfire is most likely caused by a bad coil pack, every common on these engines. By the way the VSC and other lights may turn on due to the check engine light being on, correcting the cause for the check engine light will turn these lights off after the check light is cleared, just clearing the codes does not correct the problem un;less the cause is fixed, hope this helps, thanks for choosing the justanswer site and best of luck.
