Has anyone figured this out. Mine will hesitate when i try to take off.usually around 30 mph. I have replaced fuel pump and filter. I was getting a code for throttle position sensor so i replaced throttle body code went away. I have replace crank position sensor i used bosch. I went cheap on the cam sensor then had to replace it with bosch, It was leaking oil into my plug. I have done a tune up replaced all coil packs, plugs and wires. I have had my skreem deleted. Im out of ideas.
