A mate of mine has a ls 160 and it seems to die out and nearly stall when you are going flat out forward, it only does it when it's hot and as soon as you let go of the joystick it recovers and the engine picks up speed again any ideas
Change both fuel filters. Make sure electtric fuel pump is supplying a good stream of fuel to the injection pump. Make sure the fuel tank cap is venting.
