Rough Idle at 800-850, Cleaned Throttle Body - Saabnet.com Bulletin Board
I hooked up the OBD II reader, after cleaning the throttle body, and it idles at about 800-850, but a bit roughly. O2 sensors are giving voltage (about 0.35 V and 0.04 V front and rear O2 sensors, respectively).
It starts fine, then after about 15 seconds, the idle slowly drops to the normal idle speed, then starts to idle roughly. It drives fine, though.
I did notice a plug in the intake pipe about an inch above the throttle body. I don't recall seeing a vacuum hose connected to it, and I can't find a stray disconnected hose in the area, so I assume it's supposed to be that way (there is a connected hose on my 2008 9-5, though). I'd post a pic, but can't quite figure out how.
