It's reversion and turbulence, it is very common and is asked about alot just sort the z32 out and run it blow thru and it stops all the problems..fudging the map in the aem,turning the idle up etc is just masking the problem, on another note your spark plugs should not be black either no matter what that is rich running and a bad thing to do.............as in bore wash and filling the oil with petrol (which can and does cause big end/main bearing failure) leading to oil film breakdown.
