Yo
i hate the similar issue except my car is kinda puffing white smoke and idk why i baby the car is an 06 56k miles....the idle issue is almost noticeable under acceleration. my idle accorded to the digital read 650-712-860-625-550.. its never constant and i can feel while driving i have a engine light its P0420 o2 sensor crap.. but i really don't know what it is..its beginning to **** me off

did you ever find a solution to the problem? I'm having that in my 06 350z enthusiast VQ35DE, it only happened at idle of course and it seems to oddly be worse when the AC is on. I know you posted this in 2009 but if you ever figured it out it would be greatly appreciated if you told me what it was.

no clue if you're still active. but I might as well ask. I'm having the same issue. it seems it only misfires on idle and when entering deacell right as I let off of the gas, also when turning on the AC when rpms raise to 950-1000 it seems to stop but is still very slightly noticeable. All the coil packs are new, spark plugs are new, fuel system is new, and passes compression. the engine has 130k ish miles and never throws a p0300
