Fluttering RPM and air noise?
Hey y'all, I'm hoping you can help me out.
I've got a 2012 MR, still stock (except for some mudflaps and an Evo 8 wing) with 50k miles. When I cruise around 30-40 mph or when I'm slightly accelerating (so 2k-2.5k rpm), every few seconds there's kind of a woosh sound from the engine, rpm drops by about 100, and there's a slightly noticeable drop in engine power. Any ideas on what it could be?
