RB25 idle hunt

[meatball]

Now i know this is a question that gets asked daily but im yet to find a solution to my particular issue. The car will only idle hunt on a warm start and only for a short amount of time, sometimes bad enough that it instantly stalls and i have to manually hold the idle for a few seconds.

Car is series 2 r33 with rb25det 740cc injectors power fc etc.

I have replaced the bov and cleaned iac valve and 02 sensor with very little if any improvement.

I had this issue last week, and changing the sparkplugs(decided to change oil and oilfilter aswell) seemed to help. 
My only issue now is that after 30minutes of my car being on. My sound turns into this gruggling ish sound but my temps all remain the same and idle's at 1.1k rpm stable

Do you know what AFR it is running when it has the issue? Might have to richen it up a little

Have you adjusted the idle screw recently?

Youll need a wideband to check the AFR
