No, the engine is not misfiring. I had it checked with an OBD2 scanner and ASE mechanic friend at the military base autohobby shop can't find anything wrong. The noise is only when engine is cold, after it warms up even at idle. Noise goes away.
I listened to it again yesterday and the noise is more pronounced at the lower section of the right side of the engine (as heard from the right wheel well).
