Just started having this issue this morning. Driving at 70mph and running fine. Under hard acceleration, it bumped, almost like a misfire. Accelerating from 70-80 in 6th gear it would do this. Gradual acceleration was fine. I only noticed it in 5th and 6th gear and just under hard acceleration. Lower gears not noticeable. 2012 1.4T Manual 143k miles. The plugs and ignition coil replaced recently and properly gapped. Any help would be appreciated. Just got off work, so I may not reply to any comments right away.
