New to me 1983 320i
I recently purchased a 1983 E21 320i. I'm trying to get up to speed on the CIS, but it's all Greek to me so far. The car idles very high 1300-1500 rpm, and uneven. I know to check for the usual vacuum leaks, but most of the lines appear to be fairly new. There is one vacuum line that is plugged, and one connector that is not tied to anything, which I am trying to sort (see below). Any ideas what this vacuum line and this connector are supposed to go to? The A/C system was removed by a PO.
