Hey there, thanks for the question. Does it start to bog badly and prevent you from reving any higher?Or just an obvious loss of power?Do you have a scanner that reads live data?
Ask Your Own Nissan Question
Customer reply replied 9 months ago
No, it doesn't bog, it just doesn't have any pull at that point, almost like the engine is at redline. I do not have a scanner.
Nissan Mechanic: Jake, Nissan Technician replied 9 months ago
Thanks, ***** ***** of power at high RPMS is usually related to an issue in the fuel trims and ignition timing.
Do you have any fault codes or any recent repairs or modifications?
Ask Your Own Nissan Question
Customer reply replied 9 months ago
I do not have any fault codes. I did have a new exhaust put on the car but the issue was there before it was installed. I have only owned the car a couple weeks so I really don't have any maintenance history. The car does appear to be completely stock though.
Nissan Mechanic: Jake, Nissan Technician replied 9 months ago
Being that it's an 06, is it a manual transmission? Does it burn any oil?
Ask Your Own Nissan Question
Customer reply replied 9 months ago
It's a manual. Doesn't burn oil excessively. Does burn some but have heard that is the norm.
Nissan Mechanic: Jake, Nissan Technician replied 9 months ago

Thanks, ***** ***** do burn some oil, but if it's not excessive then at least we don't have to worry about the ring issues some of these engines had so that's good.

With now power at high RPMS do you ever notice catalytic converters getting abnormally hot or anything like that?

It's alot harder to try and pinpoint what's happening if you cannot see live data including fuel trim data.

I think buying a scanner is my next move, any suggestions on a model that supports live data. There are so many, some that work with the cell phone, some not. Any suggestions would be appreciated.
Nissan Mechanic: Jake, Nissan Technician replied 9 months ago

my advice would be anything that does both live data and graphing and can read ALL modules.

there are quite a few out there, I actually keep an Autel brand one in my console for when I am not working if anyone needs my help and it has significant capability for a handheld. I think I paid like $380 for it.

Believe it or not it was the air cleaner. The car has a K&N filter, it was really dirty when I got the car, I cleaned it and put the K&N oil on it. I just took a spin with the filter out and it runs like a champ..
Nissan Mechanic: Jake, Nissan Technician replied 9 months ago
Dang that thing must have been filthy lol. I have seen mice nests in filter box cause it, but they usually start the question with (the car sat in garage for 2 weeks while on vacation.......)So glad it was an easy fix!
