Just started her up after 2 months i got a CEL for both o2 sensors after about 5 min running the car started to idle funny bobbing back and forth between 500 and 800 rmp on rest, while im in motion it drives fine but once i stop rough idle and once or twice it idled so low it shut off. read a few post and seems like i have a bad PCV valve or Hose? has anyone else had these symptoms and if so what else could be the problem, i would like to know before i go in on the PCV
