[whitestag]

help, I went to get grocerys and when I went to drive home, started the stag up,,, it idled really low and was fighting not to stall, then cleared up but wont go over like 2.3k or so,, just like its hitting limiter,, really nead help guys

Might be the Air Flow meter. When they die, the engine goes into limp home mode and idles like a biatch.

[whitestag]

o no.

how do i check the AFM....

It is raining and i heard about afm's dieing in rain, but i dont have power duct,, i got pod thoe...

Sounds like you need to visit a tuner mate. Tell them the symptoms and they can plug in their diagnostic software and suggest the fix.

Another method is to borrow someone elses AFM from an M35 and plug that in place of yours.

[whitestag]

Just checked filter and afm no moisture there at all. And it only just started doing it

[whitestag]

And now my engine light on

[ichizora]

uhh sure your AFM is working? That really sounds like an AFM is not present. Borrow someone's working one...

[whitestag]

Not sure if it's working. I gotta figure something out quick. Is it still on to drive with no woken afm?

[ichizora]

should be okay for a bit... worried about your engine light though

[bubba]

Engine check light comes on when AFM is dead, error code 12 is what you're looking for.

Edit: oh it's an NM35.. no idea then

Moisture in the AFM?

I'm not sure about M35's but most AFM are hot wire. They have a limited life due to the thermal cycles they go though. You might have even gone over a speed hump and it may have broken. The only way you can find out if they are good or bad is diagnostic software or replace it with a working version.

Try and pull some codes.. sequence is detailed here http://www.skylinesaustralia.com/forums/Ec...-W-t261557.html

and the codes are http://www.skylinesaustralia.com/forums/Ob...st-t281894.html

more than likely it's the AFM....mine died two weeks ago for no reason as well.

Get the codes.....pretty sure you can get an second hand x-trail one.....or you can go for the 1 year warranty approach and buy a new one....Hornsby Nissan had em in stock....get a price from them I'll see if I can beat it.

Any smoke?

[KiwiRS4T]

Try disconnecting and reconnecting the battery (won't help if your afm really has died).

Thanks everyone. Fault code 0100. Took a couple of tries to get it to flash, bu got it in the end.

Now to see about getting a new afm. Anyone know where is good to go? Nissan is one. Any other.

S2 m35?

Arnt wc34 and m35 different?

[whitestag]

Ok kist to check. What we have called afm is actually a Maf? Just about to start calling around to get one. Just need to know what part I need exactly

[Jetwreck]

Arnt wc34 and m35 different?

some of the C34 guys get a little confused.....I give you a heads up as they don't quite get it ......our car is 98% different to the C34! So when you hear the line "Well on my C34......" more than likely they are completely wrong with the assessment!

Sorry in advance if I have offended any C34 owners
