It's an 04 wrx vf39 swapped with supporting mods. I was thinking a vacuum leak somewhere but I can't find it. I was also thinking the IACV needs to be cleaned. What do you think?

IACV could be it. I had this same issue and after I cleaned the MAF, IACV and replaced the plugs car ran like a top once again.
