  • Bad idle hesitating F150 2014 70 hours

    Hi there

    I bought i boat with an F150 2014 with few hours. The company told me that last owner havent been using it a few years and decided to sell it. The issue was that the fuel was bad. According to the company the took all old gas out. So i did fill it upp with 30 liters. Already from start the enginge did light up the water warning. I shut it down and took out all the fuel and there was still water in the tank. So did flush it. Installed new fuelfilter with seperator and also new engine fuel filter and plugs. I did drain the highpressure resorvar/tank.

    But it dosent go 100% at idle it do miss and hesitate.


    Can the injectors been bad from the bad fuel. I mean the engine has only 80 hours on it.

    I have put injector cleaner and 2 stroke oil without any results..


    Any ideas?

    New injectors?

    send them off to be tested, cleaned and retested.
    you also need to monitor the rail pressure to make sure it is in spec
    draining flushing tank may not get all of the water out.
    may need to open tank, tilt tank or whole boat so all water goes to one corner to be sucked out, and then mop up any remaining water with rags.
    what kind of tank is it?

      Its a plastic tank. Also the resorvar have a bottom plug wich i have drained 3 times after clearing all the water.

            you still need to know if rail pressure is in spec
            along with the proper testing and cleaning of the injectors
