idle throttle hoses

  1. E30 (1982 - 1993)
    My 318is is idling all over the show. I noticed this connector wasn't connected to anything but when I stick my finger over it, the idle returns to its normal 800rpm. Can anyone tell me: a/ what SHOULD be connected here (there are no obvious hoses disconnected) b/ if it's OK to seal this off in...
