I just got my 1988 735i from my brother, (who, quite frankly, tore it up). I have never had a BMW before, so may be asking many seemingly-stupid questions, so please bear with me.
I tried using the cruise control for the first time yesterday, and set it at 80 mph. Well, even though I was on a level road, (not going uphill) it kept surging every three seconds or so. It was so disconcerting, I turned the dang thing off. Is this normal, or is it just my cruise control?
