Hi! I have a few questions I hope someone can answer. My '85 735i has started to stall constantly. The only way to avoid it is to pump the gas or floor it. When I floor it, it has very little power and surges. I checked the troubleshooting list in the Chilton manual and the first thing it mentioned was the fuel injectors. I called a local mechanic and he said the injectors may need purging. Does this sound right? What is purging? Any help is appreciated.
