Car is showing error codes p0301 and p0340? Having difficulty locating the plugs and wires to check them, its the v8 model, 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. Thanks

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.
