As I stated does the '87 740 GLE wagon have an EGr valve? It is a 50 state car if that matters.

The reason I ask is that the MPG have been in the 15-19 mpg range and it seems to cut out or stumble when driving near 55 in overdrive.

The car is my girlfriends, I asked my mechanic about it, his first thought was to check the EGR valve, but I can't find it or any thing online saying that it has one.

I keep reading about the flame trap and oil separator. She has all the records from the car and I see nothing about them being cleaned or replaced, so it that something I should do?

I was doing some more reading and came across something mentioning vacuum lines for the cruise control. She recently had the front main seal replaced and that is when this issue started. But the car had been sitting for 5 months prior to this. And when she tried to use the cruise control the other day, it did not work.
