It is an 06 600 fusion. in the past week it has started to bogg down when you are idling and go to tack off with aggressive throttle. it will sound like the motor is getting choked out and almost dies. i didnt now if it could be bad gas because my buddy when up north and melted a piston and the tech said it was the ethonal in the gas. i am fairly new to this it is my first sled.
