AFM is stuffed would be my bet.

Happened to my mates M35. Run as rich as hell, idled poorly (obviously) and couldn't push it pas about 2200rpm.

I may have a second hand AFM lying around.... or you could just get an Xtrail's AFM from Nissan and plug it straight in (my mate has a 350z AFM which works fine)

I will borrow your spare if thats ok and swap it to see if it makes a difference.

i might pick it up over the weekend if thats cool??

let me know dude, cheers

intercooler pipe has likely blown off, lol at the internet mechanics

Lol at internet comment repeaters. Good thing he wasn't waiting for your sage advice. A day late and a dollar short. Well done friend.

what,you think i get my knowledge from these forums and the internet? has the guy resolved the problem?have you got a better call cockmaster? dont call me friend either

Settle down please. Insulting other peoples suggestions, while repeating someone elses is hardly a pioneering strategy, nor will it win you many friends. I actually weighed in on this issue several days ago if you cared to look before insulting someone you've never met. But hey, you're the only person on this forum with a valid opinion.

My rule of thumb is; if you wouldn't say it to someones face, don't say it on a forum. I can assure you, you wouldn't be having that conversation with me. Your sig is right; you're as subtle as a brick to the face, and about as welcome.

aerofocker and Daleo you can both settle down, if you want internet arguments Forced Induction Performance is over that way somewhere ---->. Stagea section is for grown ups.

Anyway, I tried twice and wasn't going to post again in here...but I'll try again for luck. aerofocker, although not polite is almost certainly on the money.

Have you actually checked for an intercooler pipe problem?

It is 10x more likely than an afm/fuel pump/fpr/earth or whatever other suggestions have been made. The pipe will most likely be on but not tight (eg loose clamp, or maybe a large split). It is only opening badly under boost. It idles better or worse some times depending on how well the pipe is sealing without any clamping force on it.

Yes it is harder to check than changing an AFM but I generally try and work on the most likely cause instead of the 1% long shot.

Thanks for the help guys, I have had a good check of the piping and cooler, I believe the car is in limp mode so it's not letting me get to boost rather than it not being there, I'm swapping the afm today and will let you know how I go. Cheers

well i had a similar episode in my 'line...

i was boosting out of a roundabout one night and suddenly lost all power, she coughed, and then died! I had heaps of fuel, was cranking fine, just wouldn't start. managed to get it to run rough and limp it home, found out next morning my shitty pod filter end cap had sucked right the f**k off the filter, and up against the AFM wire, so that it couldn't register any air flow, and three fifths of f**k all air could actually get past anyway. i simply removed the offending filter cap, replaced with a k&n and bingo!

i dont know if you have a pod or not, but hey thats my two cents, and what happened to me. i guess the simptoms of what happened to me and blown piping are the same because the problem is the AFM not getting a signal.

cheers, Rowdy.

im here to solve the dilemma guys

i swapped AFM's this morning with Cam and worked a treat.

resetted the ECU and all good.

thanks for all the help. would have been in the dark without Scotty and Cam.

Nice to have some "internet mechanics" that know what is going on, aye? :blink:

smart arse.....yes you are...LOL

I will defend my call of intercooler leak as at that point we had not been told about the engine light coming on.

Once that was in the mix, had to be an electronic fault....

:D

No need to defend yourself andy, it was a good call. :blink:

I have asked Garett to bring the sensor around to have a look. It's probably a dry joint on the cct board and I want to see if it is repairable so we dont need to replace them when they fail.

ill come past next weekend Scott if thats cool with you.?

Really!!!

AFM wasn't it! lol....work at a dealer servicing car's aye!...only asking because your diagnosis was about as accurate as there's would have been!

P.S. Most of us know our car's fairly well....you got some kind of in site into VQ25DET's that we don't know and you can share. Before you slag off the so called internet mechanic's maybe you should at least work at getting you diagnosis correct first!....and remember that some of us have quite a high level of first hand knowledge!....remember this isn't REXNET!

    • FWIW a lot of the local owners that do a big build tend to have cars that are perpetually broken. 
    • I just got this system but haven’t installed yet I got a Moroso sealed box (defect reasons) which will be set up same as their pic The quality is high grade, the correspondence I had with the owner (former head designer for Rockford Fosgate) was unbelievable, guiding me with what I needed. Even told me not to buy some things as it could be sorted in a different way at his loss. Just a bit of a bite with the exchange rate and don’t purchase gear in 1 hit that goes over $1,000 au, lol I forgot!  
    • Thanks mate for that reply. Very helpful.    it’s a 2022 400R so would most likely lose those features as you say.     I did a quick compare of a rv37 nav and heading for sale in Japan to q50 model. I’ll pop pics below. Seems  Japan spec head into top, nav unit second below it   below pic Q50 aud delivered     differences seem to be Aus delivered has a different plug top left hand side of head unit- not sure what and where it goes.   and nav unit Japanese tv37 had an extra plug put    Again I’m really not sure what each of these differences mean!       the actual plugs on a v37 and q50 screens look identical on both screens… pics below for comparing. (One screen was is a us delivered one) but should be same gps signals etc as Australia.    If it were as simple as swapping a nav unit from q50 aud delivered im interested -just want to figure out what the missing plug is for before spending big $ on a second hand part for it to not work, and I guess with the head unit, if the band expander does the job (I got a 20mHz so should get the range I’m after) so should narrow my issue down to nav unit only.  I’d love to know what the extra cable on rv37 does and if I eliminate that part what it’ll do to the setup,    and also, if I can figure out what that head unit plug difference is, what does that cable do and where does it got can it be altered or re-plugged?! Excuse my ignorance what is ACP/AA, what does that stand for? (Apple car play? Android air play)? so If I swapped head units to save using a band expander, I’d likely lose those better features to have an oem Unit operational. Better to use a band expander and retain AirPlay options and newer version of head unit     provably best to band expand it, and focus on the nav unit. th isn’t  a big deal/ would be cool to have it working  from what I can tel we use a PAL Signal and Japan uses a NTSC signal  I don’t know if there’s a co better or if the screen only reads NTSC, or if it’s the tv module that needs replacing… no big deal don’t need it but more of a curiosity thing on that!   Thanks for the info re tyre sensors, helpful and great to know.  I was reading the online manual off Japan website and it seemed to make it sound more confusing than it is  I guess a rim replacement would require the sensors to be moved to a new rim to carry that option over?!     Thanks for the info regarding diagnostic mode. I appreciate your help mate. Trying to brainstorm here to find a solution to get as much gadgets as I can working! I plan to get my local Nissan tech to have a look too who used to be at an Infiniti dealer back in the day to see if any thing they have or idea can find a soliton. But hoping anyone here has gone down the same route to make life easier!!   i guess identifying the cable/plug differences and what they do would be a great way of finding out if the units are transferable    thanks again 
    • No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.
    • There is a known issue with the mix door motor on the Q50 which causes these symptoms, not sure if it is common on the Y51 though.
