I have a 92 civic cx that was swapped with a z1 (previous owner). When cold it idles around 1000rpm and is smooth at idle but once it warms up it idles on the peg (below 500) and misses. Also every once in a while, while I'm driving in first or 2nd at around 2k it'll bog out for a few seconds and if I hold my foot at the same throttle percentage it'll pick back up and take off like a bat out of hell without me giving it anymore gas. I've already cleaned the iacv and it didn't change anything. Could it be a vacuum leak somewhere? Any help is appreciated
