New Plugs, New Plug Wires, New Front and rear O2 sensor.
Replaced MAF, Cap, Rotor.
Had P0301 Code and rough Idle at take off. This was fixed by cleaning EGR.
No codes now, only the following, issue that can be created.
Speed up to 2800-3000 RPM and let foot off gas pedal, then If I excellerate, it then seems that gas is cut off at this point, will only speed up IF downshift occurs.

This also seems to happen when in second (2) at 4500 RPM.?
