hmm so this is pretty common huh? the exact same thing happened to me, had a code for lean on both banks, the rubber elbow was gone and was sucking air bad, i replaced it but i can still hear that something is sucking air somewhere but definetly not the elbow anymore, the code is still there but the engine is running much better i just haven't got a chance to look for that other vacuum leak
