RAYMR : do you know exactly where this valve is located? I have of two different places. One person told me its at the back of the firewall and someone else said it was near the distributor. I also need to know how to remove.

My car has not stalled when engaged in gear lately, but this evening something different happened. I was driving about 45 mph on a 4-lane boulevard in town and had to make a sudden stop, as someone had stalled out a traffic signal. When I came to a stop, my engine stalled - right in the middle of the road. Luckily, it immediately started right back up and I went on my way. I also noticed today that sometimes when it is idling in gear, it will have a very sporadic and quick "stumble", like it wants to stall, but it does not.

You asked about power - its not a tire burner, but it will get along pretty well. You mentioned rings. It is not smoking or burning oil, so I guess they are OK. The car has 264K, which is a lot of miles, but from what I understand, this should not be the end of the road for a typical MB V8. ??

Thanks!
