Air Flow Meter Query

[zac.r32]

Alright fellas, so, my car has been idling funny, missing and shutting down while idle etc. And it's come to my attention that its most likely the airflow meter.

Just wandering, will it make much, if any difference if i put an AFM suited for an rb25det, on an rb25de? im having a hard time finding an rb25de suited AFM on ebay.

Cheers.

no not same, put your vin number in at amayama and check the Nissan part number, I'm under the impression 25de use the green label like the RB20DET uses.

Green label is correct

[iruvyouskyrine]

If it's S1. S2 all use pink label iirc.

I've heard green label, i checked mine and it was green label.

Also, today i tried unplugging it and running the car without one, but it ran like a piece of shit. basically ran the same as when it plays up, except when its connected it goes away for a while. (edit) just been informed this is due to limp mode.

Ill explain it so i can get a few more opinions;

When i start the car up cold is when it's at its worst, the idle will bounce up and down for a bit, sometimes sit at close to 2000rpm for a while, and i have to wait for the engine to heat up a bit before its driveable. if i try drive it before its warm, the car will stutter, and rev's behave as if they're hitting a limiter. if i idle and rev the car while its playing up, it will also behave as if it's hitting a limiter, at around 2500-3000 revs. recently its been quite hot and ive noticed the car has been able to drive straight away from a cold start, but in a cold climate it will play up.

The car will drive fine for a while once warm, and have the occasional miss and lose power for a bit, but it comes back. might do this a few times before back to normal. It hasnt been too bad recently in the hot weather. Also, when im idle, sometimes the engine will just die.

Thats all i can think of at the moment.

Do a search for re soldering the connectors as well that usually works

The car seems to run worse on colder air. does this sound like an airflow meter?
