I've had a FMIC fitted in the last few weeks and since i did, ive been having trouble with very low rev drops, and sometimes stalling. its mainly when i put it into neutral coming up to intersections, or just with the clutch in coming up to my drive way. Ive searched a heap of possible causes for it but my car ran perfect before this and it seems like too much of a coincidence to me. Any suggestions??

i dont think ive been blowing smoke. i did actually notice yesterday that the 1st rubber hose coming off the cooler on the passenger side had a bubble in between the metal fasteners were the pipes would meet. this might be the problem.i could have a leak there. i'll play around after work tmoz and get back with the results.

on idle what are ur revs? i had to tweak with the idle on my plenum coz my revs were to low

On idle it is fine. it doesnt hunt at all, and sits on about 700RPM roughly. its only while driving when throwing it out of gear into neutral that the revs drop to nothing and sometimes stalls.

I installed a fmic in mine last week too (r32 gtst) - same thing happened with the stalling. But it only did this for about 5 mins - then one of the silicon hoses blew off the piping. Turns out it was just not done up tight enough at one of the joins (must have missed it somehow in the rushed check:)

Anyway, once the connector was done up properly the stalling is gone and the idle sounds much better too. I'd check the connections, especially if one's got a bubble in it.

I think i might have fixed it. it didnt do it all this morning driving to work. last night i tried to fix up the bubble and its pretty well gone. think it might be slightly stretched. i spose we'll see over the next few days.

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
