Z does not accelerate

markesc

Just had something similar happen for the first time today:

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.

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!
