So i replaced the fuel filter, new spark plugs. I took it over and got a power programmer from snapon, and tested it. The MAF, Injetor timing, and O2 are all fine. What happens is, when you floor it, it kinda of feels like its running on 3 cylinders. It bogs and looses power. Sometimes it kicks in and out. When you dont floor it it runs fine. Any ideas?

it's a possibility that it's your EGR/AIV. Just take it out. It doesn't take long, and it frees up space at the same time.http://www.nissaninfiniticlub.net/fo...threadid=26150

took it out, helped a little but it still stumbles.
