  1. 1989 Nissan Sentra TBI PCV valve location

    Classic Datsun
    Hello, I've got a 1989 Nissan Sentra 2-door sedan with throttle body injection and it's experiencing very rough idling, etc. Seems like it could be the PCV valve. Only problem? I can't find it! Can anyone tell me where the PCV valve is located on this car? Thanks!
