  • 2003 f115 4stroke idle issue

    Hope someone has some input: Engine will not idle and runs a bit rough at higher RPMs. Cleaned VST, chnged fuel filter, serviced injectors.

    I did note that when I unplug the idle control sensor then plug it back in, it will idle but rough. As a matter of fact it will idle better with the idle sensor unplugged until I shut the engine off. When restarting it will not idle unless I repeat above.

    About ready to give up and take engine in to a yamaha service center but they have a 4 week wait until they can look at it. Any ideas would be greatly appreciated.
