Yeah, unmetered air the maf isn't seeing but the 02's are so it compensates and adds more fuel. If you have a scanner with datastream, one or both long term o2s will be reading high positive numbers like 15+ at idle. If you rev it up to say 2-3k, the numbers will drop to at or near 0 which would indicate a vacuum leak.
