2014 7AT 41k miles, FI exhaust + K&N drop ins. Cold start, everything seemed fine until about 5 minutes later the car would not go above 4k rpms. Basically no power, a PRIUS would be faster!!! No CEL either.

Now at home with a loaner awaiting the bad news...

So I gather they will try the following:

1) Blame the k/n filters, clean the MAF sensors, coin-toss if it goes away
2) Problem will return, then they will clean the throttle bodies and/or replace.

I have the extended gold warranty or whatever the hell it's called.

Never once had a single problem with the car up until today
Thats best case if the mechanics at the dealer know what theyre doing. Don't let them see your k&n's, that is if they dont blame it on the exhaust as one dealer said to me. They always find an excuse to not honor warranty. :shakes head:

Well, coulda been much worse.

I'm out $100 for a MAF sensor cleaning and software update. It is what it is, funny the car seems to be much more responsive in the lower rpms. Wasn't going to sit there and argue with 'em, just happy to have it back, but I did let them know that there's multiple mile long threads online about the same issue.

Maybe Nissan has figured it out with this "update" or that was just BS and they just unhooked the neg battery terminal: "that'd be $100" like:

Good to know you have the car back to normal now. FYI, cleaning the sensor is a breeze, youll have to do it every few miles. As for the TB, cleaning them should also be a maintenance item, every 10k miles for me. Theyre pretty easy to clean but you gotta be careful not to mess em up, as theyre really sensitive. For peace of mind, this is the only reason i take the Z to a dealer.

Good luck! :driving:

Similar Issue
 
I just had this issue letting my car sit for a week. 2014 Base model Z, 6MT, Stillen CAI and oil cooler are my current set up. Problem happened twice where my Z would not accelerate when flooring the throttle. I cleaned my MAF sensors and changed from oiled filters to dry filters. Problem seemed to go away for now.
I am barely at 16K miles on my Z. I will clean the throttle bodies at 20K miles now that I have read this thread

Careful taking out the TBs and cleaning them, they are sensitive

Hello I just want to share that my 370 was going through limp mode for about 6 months. How I dealt with it for so long? I was lazy and figured I just had to turn off the car and wait 10 seconds before turning it back on, to work properly again.

Finally after doing some research I cleaned my DIRTY TB and limp mode has been gone for 3 weeks now, along with the codes P010B & P102. Huge thanks for this forum that helped me, through you guys experiences solve my issues. I love my Z again thanks to you guys.
