'85 745i fouling plugs on cold start (archive)

That is, very cold start. If the car has been sitting for several days or more, I'll hit the key, it will start right up, then stumble and die. This will continue unless I "blow it out" by winding the piss out of the engine a couple times (of course I'm sure to do this before I've taken it out of park). One time, it ended up completely fouling 3 of the plugs and I had to drive another car to work. My first thought turns to some kind of faulty sensor that's telling motronic to give it way too much fuel, basically flooding the engine. However, I don't want to just start throwing sensors at the car in hopes of stumbling on the solution. Any thoughts?
