Cx is running rough, vibrating/sputtering. Engine light came on blinking, when I attached my code reader it showed the above codes? What can I do to fix it.

PO301 is a cylinder misfire, cylinder 1. Pull the plug and check it and the wire to it. The PO340 is a camshaft sensor issue. Check the plug first. It is the easiest and cheapest fix. NOTE: Either code could set the other code.
