Q: My check engine light came on with code P0303 (Misfire in the 3rd Cylinder), Can I drive it until next Wednesday without damage?

Hi, thanks for writing in. I would not recommend driving it much as an outside force out of your control can cause a dangerous accident. As for a spark plug replacement, someone on our customer service team can quote the repair for you. I will send your situation over so they will reach out to you with a quote.
