Hello all,

First time poster long time lurker. Please forgive me if this issue has been talked about or resolved but I couldn't find a thread that exactly had the same issue as I am having. This is what has been happening and any input is greatly appreciated!

About 8 months ago I got in my 2013 370z and it was a very warm day in the summer here in the Orlando Fl area. I live about 1 mile away from a main road so I didn't notice the lack of power until I pulled out into traffic. I put the pedal to the floor and it slowly and I mean slowly accelerated. Once I hit about 3500 rpms I went a little quicker but not by much. I pulled over and turned the engine off for about 30 seconds and back on. All was good. I didn't have a repeat of this issue for about 3 months.

Then about 5 months ago which was 3 months after the initial incident it started having this problem very sporadicly I mean maybe once every two weeks or longer.

Fast forward to this month and it is now happening about everytime on cold startups. It hasn't done it that I can remember after the engine has been on only cold.

My buddy just got a job as a tech at a local Nissan dealer and I have now brought it in twice. He replaced the brake light switch per recommendation from the master tech saying that could especially on an auto tranny cause it to go into limp mode. Unfortunately no fix. Last Friday it happened again about 2 days after the brake light switch was replaced but this time it threw a SES code. The code was bank 2 MAF. Took it to the dealer again we check the MAF that had thrown the code nothing wrong. An update was done to the CPU. It seemed to drive different for about 4 days but now since then it has done it twice this week.

I have the stillen gen 3 intake system installed and that is all that I have done. At this point I have about 5 months left on my warranty and we are all at a loss. Does anyone having any suggestions or resolutions?
