2005 Ford Escape P0306 Misfire: How to Diagnose and Fix When It Only Occurs in Rain
I'm experiencing a P0306 misfire code on my 2005 Ford Escape, and it only happens when it rains. I've visually inspected the spark plug coil and don't see any visible cracks, but that doesn't rule out internal damage. The wiring connector appears intact, and the spark plugs are relatively new. Given this, should I replace the coil pack for cylinder 6 as a first step, or should I investigate other potential causes? Any advice on troubleshooting this specific issue in wet conditions would be greatly appreciated.
A P0306 misfire on the 2005 Ford Escape is fairly common, and a faulty coil pack is often the culprit. Try swapping the coil pack from cylinder 6 with one from another cylinder to see if the error code changes. If the code clears after the swap, it confirms the original coil was defective.
