This happened to me multiple times over the summer in a 2 week span. Had no codes or cel but I cleaned my mafs made sure all my piping was secure and I haven't had a limp mode since.

Exact same symptoms. Happened probably 6 times within 2 months (about once a week). Had the throttle bodies cleaned 8 months ago hasn't happened since. 10k miles since cleaning

Apparently our throttle bodies are very sensitive to very mild build-up. Venting into the intake doesn't help.

I took it to the shop and the codes indicated the MAF sensors were faulty. Replaced the sensors, all was good....for about four days. The ses light came back on wtf!!?? Apparently there is a tsb #15-058 for codes P0101 and P010B for all 2011-2015 370Z coups and roadsters which is an ecu re-flash and should be covered under your emissions warranty. I just had mine done today, hopefully this fixes the issue.

I just had my CEL come on yesterday as soon as I started my car and along with it came very poor acceleration as I and others have stated. I had a P0101. The tech updated the PCM per TSB 15-058. Hopefully this solves the issue.

I never cleaned my throttle bodies or MAF's like I said I would in an earlier post.

6 or so intermittent times I start from cold and there is lack of power. Did not notice any lights on. Stopped and restarted engine 2-3 times and then full power is back.

cleaned MAFs today

Why can't I find TSB 15-058 when searching internet?

I changed out the MAP sensor (got one used from Z1), and it made a big difference. None of the weird throttle/power issues after a long drive. Dealt with it for years. No code either!

Cleaning the throttle bodies worked for me too.

This has happened a couple times this winter for me...very frustrating. I can usually drive it and once it's warmed up I restart the car and it works fine.
