BMW CEL Issue

I think I diagnosed the problem, but I thought I would consult the PPOT Brain Trust for further guidance.

Earlier today, I noticed that the CEL on the 1993 525i had come on. I was only a mile or so from my apartment so I got the car home and then went online to figure out the issue. I was able to read the code as "1222" which indicates Lambda Control 1. From reading forums, that seems to be some type of air/vacuum leak that typically messes with the air/fuel ratio. When I was driving the car, I did not notice any change in the driving characteristics (idle was the same, no loss of power, no funny noises, etc).

My main question would be if any of you fellow BMW owners have any experience with this? Also, how drivable is the car? I do not plan on taking it anywhere for now, but the dealership is an hour away and if I could avoid the hassle of getting it towed, I would be very happy. Thanks as always
