Check engine lights and the OBD system are geared towards emissions related problems, and not for all engine/trans problems. There are a host of mechanical problems that will never show up as a DTC. I'd get it to a mechanic and see what is ticking. As to your question, yes a bad PCV or elbow can cause rough running/idle.
