What are the symptoms?
Where in the RPM range is it loosing power? etc...

you put your foot down in 3rd gear get to 2500 revs and then it hesitates before revs pic up .

Assuming it behaved no differently before you changed the fuel line parts, and that this is confirmed as fine, I'd be checking the mass airflow sensor.
This part can have a major effect on fueling in the engine speeds you indicate.
Check the EC section of the manual. Page EC-360.

Have a read through this thread from post 1, and see if anything looks familiar...

But personally, given the coincidence, I'd be revisiting those filters as well...plenty of instances of power loss on the site due to crappy aftermarket
filters.

They don't need to be expensive Nissan ones either, just a good known brand.

The ones that the Opie Oils guy ships are fine - I've used them on my T2s and my Z4.

thanks for your help and it is the air flow sensor ,when i fit a new one will it need programming into the system .

No calibration required, fit & forget.
Do try to ensure that you get a genuine Bosch device, there are a lot of Chinese copys out there that seem to fail prematurely.

good point, if you still have your old air filter try putting it back in. Also check that no loose fibres from the new one have ended up in the MAF :thumb2

If you mean KnN then go for it and stick an induction kit on, assuming you're not offroading in deep water :sly

Just had a quick google image search and it's a doddle :thumb2
Seems like the same sort of set up as 2.7 ie filter box, intake pipe with MAF then I/C etc.
