This situation happens in 110-112 mph(almost),rev speed is 3.5-4K(it's 4AT).

When accelerate during 0-110mph,it performed normally,the engine&gearbox works well.

So I really dont understand(My car is US version,does it matter??)

You said"fuel-cut",does this engine will do such thing like that?
Or you mean the fuel pump may risk?
But during 1st-3rd gear it all performed well,why??
