I really think that's a possibility. Sadly I have limited tool part ect. Hopefully the shop will have something tomorrowMuch wiser minds have commented on this than I and I assure you I know nothing compared to them. BUT some years ago I had what sounds like a similar problem with my ‘09. Erratic idle and would chugg chug on acceleration and sometimes would clear. Worse when hot or even just warmed up. We went through everything mentioned above and more, replaced map sensor, loaded various tunes, new spark plugs, even had the injectors ultrasonically cleaned. Nothing worked. As a last resort I put a new set of plug leads on. Bingo! It was perfect. If your coils are fine, it could be a leads. Just a thought.
