I've been dealing with this issue for 3 years. Every time the nissan specialist would come out he couldn't re-create the issue. I sent him this link and videos i've taken myself. Luckily every "fix" they made was covered by nissan. Yesterday though he flew up again to see if he can duplicate this issue and finally it happened to him! He hooked up his data recorder to the car and got loads of data to take back to the engineers. If it ends up being a AT problem i'll be pissed because i just replaced my transmission back at 60,000 miles. I'm just glad he got the data that they were looking for in order to find a solution. my350z forum under 370z section, others have suggested MAF sensor, but we'll see and once i do get results i'll post them.
