I have had new plugs put in...an APR software programming...no codes...no CEL...Audi mechanic could not diagnose issue with diagnostics...nothing showing. No IFs, ANDS, BUTS about it...this car has a slight hesitation...missing issue on slight acceleration in every gear. Seems especially more pronounced as the engine warms up but could just be me going crazy by now. Definitely feels like something electronic. I want to sell this but I need to find a solution. Anyone have any ideas?
