    This has happened once or twice before. Car sitting all night. Temps are about 8 degrees outside. Cold start the car idles very rough around 1K RPM. After the car warms up all is fine. Runs fine with no power loss or idling issues.

    Service engine Soon light is on. Head to autozone and the code reads P1351 (Misfire cylinder 5 with fuel cut-off.

    After reading many forums I think I will replace the coil. I replaced the plugs about 6 months ago. I will pull the cylinder 5 plug and inspect anyway.

    Possibly vacuum leak, so will inspect hoses.

    Any other suggestions?????

    Usually a misfire on one cylinder indicates a bad plug, plug boot, or coil. You can try putting on a new coil boot if you are strapped for cash, or swapping the coil (minus the boot) to a different cylinder and see if the code follows the coil.
