First thing I'd check is if the exhaust manifold or piping is hitting something. If that's not it, you may need a tune. FSM may have some clues.

I've been having the same issue since I bought my Nismo. Dealership has changed the Gas, the oil, did a compression test, a leak down test. It still happens. It will be looked at by a Nissan Engineer on Monday. I'll let you know what they say.
