    throttle body butterfly adjustments help

    when you let off the throttle should the butterflys be shut all the way in all 3 bodies?

    When off the throttle they should all be shut on the stops. If they are fully closed your engine will stall. Full closed on the "Stops" there should be a small gap, not full flush closed

    what will happen if they arent adjusted properly?

    what symptoms will the ski have if they arent adjusted properly? I'm having a problem at idle. Ski wont stay running without any throttle...summer is a wasting and i cant get this thing running. thanks for your help.

    first hold down the function button until the codes show up. See if you get 01, if it is something else let us know.

    It flashes 48 very quickly.then 01 stays on the screen. I recently changed the throttle bodies and am thinking they are out of sync .

    No I haven't tried that yet. I am going to pull it back apart tonight and replace the tps and try to set all the butterflies. I will turn up the idle speed then. It's just turning the screw right? I have zero experience w EFI engines...ideas?
