R33 Gtst "sluggish Like" Idle Comes And Goes

[33salad]

Greetings SAU

My r33 has come up with this annoying idle issue. From a cold start it tends to do it once I give it a slight rev or if it's been running for a minute or so. It sometimes goes away (easy to tell when it's got the sluggish idle compared to how it's suppose to sound)

It also changes the way it takes off it feels as if it's struggling to move, I haven't tried to hit boost while it does this, It also seems to happen when it's warm too (but less frequent and goes away when revs get above 2.5-3000).

However, when I was driving it the other day would of been hot as it had been running for a while, I hit boost in it then it just randomly stalled while I was driving. I tried to start it again it would start fine but then the revs would drop and it would stall pretty much 2 seconds in. I had to pull over because it pretty much would just keep stalling. If I was to rev it to stop it from stalling it wouldn't like it (kind of sounded like extra air was coming out the exhaust or something similiar) I sat there with it off for about 20 minutes to turn it back on to the same issue I was able to drive it home but it struggled.

I hope this makes sense I don't really know how to explain it that well

check your pipes for an air leak maybe?

split hose or anything like that

Do you have a BOV on it? Sometimes if they don't close properly after a boost then the car would not accelerate and keep stalling, it would also sound like there is air leak

i just blocked it off and it happened again as i was slowing down to a red light, i pretty much had no power and the revs would drop pulled over and it magically went away a few minutes later

if there was a air leak would that effect me in boost? because 90% of the time i actually take the car out it will hold boost and drive fine. just these random incidents where i could have had it on load or just slowing down to a light

i do notice how the flutter is more 'pshshshshsh' if its low revs but if its high revs its a 'pshhhhhshshshshsh'

i noticed that the a/c belt has torn itself does that have any other significance other than a/c?

thanks

also what i meant by when it has no power is its telling me im on 2k revs when my turbo is spooled well above it its like all the air is just coming out my pod filter

That makes so little sense it's not funny.
