Hi, my '89 760GLE has developed a stalling problem its a super-pain, whenever the revs get too low (when I quickly take my foot off the accelerator pedal, slam the barke, drive slow up hill, sit idle in traffic for ages, etc...) instead of keeping the revs high enough to keep the car running, the car will just stop. what could be the most common cause of something like this? Your replies greatly appreciated. Shane.
