Its not really a popping noise, sounds more like a fluttering or a very light flapping noise when I decel in gear or rpms drop when I pull in the clutch. I've also definitely noticed a decrease in power during harder acceleration. Feels like it takes some time for the throttle input to register. I was thinking vac leak somewhere and I've checked the acorns on the exhaust and they seem tight. Anybody had this before or have a good place for me to start?
Thanks in advance.
