Wow, i've got a '13 touring sport too and same thing! Dealer didn't see anything when I took it in for an oil change.

As for the brake sensor - I don't know about that...if you're driving and you lightly tap on the brake and the accelerator, you will know instantly that you can't accelerate. It wasn't that type of feeling but rather the car accelerated rather slowly.

I took apart the intake and cleaned out the Throttle body (which wasn't all that dirty) and also cleaned the MAF sensors. I didn't have time to take off the bumper and look at the intake filter but i'll let you guys know if cleaning the TBs/MAF helped.

No lie, it happened to me last night again, this could of been a fluke, but I lost acceleration power again, so I pulled up on the brake, acceleration back.

If it happens again, I'll report back here.

Wow! that's crazy.

Yup. Thought the dealership guy was pulling my leg, but it worked last night. They said the sensor just reads it wrong and that's what gives the acceleration loss, but we'll see next time.

I'll have to try this in the event it happens to me again. But you know my car felt/sounded different after this event. I reset the battery and the exhausts opened up again.

3 types of limp mode happened to me.

causes were:
1) when I bought it brand new and drove home, engine was breaking in
2) brake light switch was constantly turned on (overrides gas pedal)when it was making contact with the brake pedal constantly
3) low engine oil

Yeah #2 was my issue.

yep I was freakin puzzled when this happened after a shady shop did a brake fluid flush. he was pretty violent with the brake pedal and that might have shifted the pedal position to hit the switch

edit: you can adjust the position of the switch to sit lower

There are also problems, such as 09 g37.
can not climb above 3500 rpm.
When you press the accelerator happen engine strident.
The problem disappears when you restart the engine.

Weather:
Below 0 degrees
Fog or high humidity

Because of the maf sensor or Throttle Body supercooling ?????

Yep... this happened to me today. 2014 Nismo, 18k miles, CAI Gen 3, FI test pipe and CBE w/ uprev tune done about a year ago. Car never tracked or driven to it's limits.

Car is kept in heated garage year round and went to work this morning over in PA at 13 degrees, no issues. Left work around 3pm and 5 minutes into ride I get no throttle response. Takes long time to get up to speed...but I'm not limited to the 3500 rpms.

Get home, have a beer, read this thread, finish beer, take car out for a spin and just like most people here it's back to normal. LOL.

Will post back to thread if it happens again and what additional actions were taken.

Has happened to me twice in my 2009 Stillen SC 370z a7

Happened to me this morning, was driving very normally. I had the music playing so I could not hear much of the engine, started feeling the engine cutting out and bogging every time I tried to get over 2500 RPM, regardless of which gear I was in. Drove home slowly, turned of off and restarted it a few hours later, no problems since restarting.

Not sure what the cause could be but some things:
- the car was fairly low on fuel, a few minutes of driving after the restart my fuel range indicator came on.
- the car was recently washed. With my Stillen SC setup the pods sit just behind the front bumper exposed. Very likely they were soaked a bit during the hose washing.
- the music was running and I was playing around with the audio settings at the time it happened. (Bose system)

Still no ideal?!? Mine never happened again knock on wood. Crazy. Can't wait to find out what it is. Next yr is the new Z fingers crossed (never ever buy 1st yr productions)

I need to add#4 to limp mode.

4) MAF code P0101, P101B
possibly related to K&N filters oversaturating the MAFs and damaging them.. I've changed back to dry filter, changed MAFs twice, and still having this problem intermittently. went to different shops, nobody knows how to fix this. I am told that throttle bodies are probably not the culprit and waste of time cleaning. but there was a thread about people reporting the same issues and cleaning throttle bodies fixed their limp modes and codes related to the MAFS.

This just happened to me yesterday afternoon.

I had stalled while exiting a parking garage, foot slipped off the clutch. While driving on the street, I was trying to get into the left lane, and it was slow to accelerate. I tried to downshift from 4th to 3rd and the RPM's were high, but the car was taking forever to accelerate to a higher speed.

It was like shifting from 2nd to 5th sluggish.

Took it to the dealer to have a technician drive with me. After car had been turned off for 10 minutes. Took the technician for a test drive and bam, it's back to normal. Technician said to just have them check for any error codes and none found.

Car is running back to normal, but going to keep monitoring it.

Luckily I found this thread too. I couldn't find anything with my search queries.

mines doing this now too. 2013 with CAI G3 and FI CBE. it was doing it in the morning when i leave for work, then it quit for a few weeks. now its doing it when i leave work.

i just got a p0101 code today. im not sure how i should approach this.

any advice?
