When I went to get on plain there was no power and took for ever once I was on plain it ran just fine. Did this twice. Then like nothing ever happend it runs like new the rest of the day? Any Ideas? Should I get it check out or maybe just somthing was cloged up and the bew out?

    Thanks

    Sounds like a coil going bad. Often intermittent at first. When they go "poof" often it is just droping spark on that hole and you can run on 5 cyl. Other times when you are 25 miles off shore it melts the wiring harness and you get to meet the Coast Gaurd.

    Get it checked out - ask your servicing dealer to reference Service Bulletin 2009-26 if it is a coil.

    Definitely a good idea to have it checked.

    Also recommend you check your CRANKING BATTERY. LOAD TEST IT.

    The bare minimum available capacity is 800 CCA or 1000 MCA. Keep in mind- it you're planning to run graphs and pumps, you're going to need MORE CAPACITY!
