Your car doesn't have a barometric pressure sensor, or MAP sensor. You have an airflow meter (AFM). If it's bad, unplug the AFM, unclip the top half of the airbox and loosen the big hose clamp holding the intake boot to the AFM. Remove the four nuts inside the top half of the airbox and the AFM will come out. Installation is, as always, reverse of removal.

Actually, some e30s do have a barometric pressure sensor. It is a small module mounted to the side of the airbox on some of the earlier cars. I've tried unplugging it and everything else to try to figure out what it does, but nothing changed. I wouldn't worry about it at all. That is, assuming that you are talking about the same thing I'm thinking of, heh.Comment

they are on early cars, look in your bentley at the jetronic/ motronic fuel system diagrams.
Your idle is most like a combination of other things. mostly tune-up stuff.Comment
