D22 yd25 stalling/eratic idle

Help Support Nissan Navara Forum:
Hi mate, have you changed your fuel filter lately. If you have reset your ECU. That can cause that to happen. Reset it anyway it won't hurt it try. Their are threads on here on how to do it. Mine will sometimes idle rough on a cold start and smells a bit rich but I think it is just how they are. The stalling issue I have only had after doing fuel filters. Apparently nissan reset the ECU after they change it due to fuel rail pressure rising with the clean filter. Hope this helps

Hello all,
To save a new thread, I'm having similar problems in my 2008 d22 2.5 except mine still does it when the engine is hot as well, however it doesnt seem to be as bad as it is when its cold. I have replaced the fuel filter, reset the ECU and the neutral position switch is working also.
I have posted a video on utube below, the video was taken when the engine was cold (last night when leaving work). You can see the idling is rough and when I rev it up over 1000rpm and hold it there it jumps around and eventually stalls....

I have a OBD2 tool in the mail as I type this, but not sure if it will say much as its not throwing an engine light.
Any ideas would be great.
Cheers
Tim

Try and clean the MAF sensor. Not sure if you know where it is so it's the one in the air filter tube before the turbo. You can buy MAF cleaning spray from super cheap etc. don't touch it or wipe it as if you damage the wires in the sensor it will require replacing and they are not cheap to buy. If you are using air filters that require oil such as a K&N they are prone to giving you problems.
Cheers.

Cleaned the MAF and put back together and no change 
Going to buy some fuel additive tomorrow and see if that cleans up the injectors perhaps.
Any other ideas?

no im not using a genuine f/filter, I havent had this problem before and using the ryco filters every time.
Ill make this addition next time I change the filter tho.
Ill try the injector cleaner and report back.
Thanks for the tips!

Well, ran a can of the diesel purge through the injectors and a few tanks of diesel with a fuel additive and its all good again.

Sweet as
Erratic idle and occasional loss of power on acceleration
G'day everyone, I have a Navara 2008 D22 DX with a YD25 (2.5l common rail turbo diesel) engine.
I learnt a great deal from the forums and wanted to share my experiences with this engine.
I bought it in May 2012, and it had an erratic idle on cold start. then it developed an awful chain like noise on cold start too.
That turned out to be a loose fan belt, despite the dealer telling me it was a timing chain issue that only their genuine parts from Japan would fix ($4400). It went away when i poured water on the moving belt and disappeared when I had them replaced ($100)
Over time it would stall occasionally. The erratic idle became all the time not just when cold. Then it began to be sometimes unresponsive to the accelerator and would 'hesitate' even on warm idle.
My mechanic thought it would be best to replace the injectors, but again i wanted to try something cheaper first and studied the forums.
I checked the MAF sensor and found that was dirty so cleaned that and then had the suction control valve replaced and what a difference!!
Its like a rocket! OK a diesel one. haha
Thanks everyone.
