2004 SRX Northstar. 60k miles. We're the original owners. Has always run flawlessly. Today, check engine light came on, and car started running rough at all rpm's. Checked with my code reader: P0304 & P0305. Indicates misfire on cylinders 4 & 5. Anything special to look for other than plugs & wires?
