Engine Mechanical problem
1991 Other BMW Models 6 cyl Two Wheel Drive Automatic 150000 miles

Okay, I was driving down the autobahn at about 245kph when I had to slow down for traffic. When I tried to accelerate back up, the car wouldn't pick up speed. I exited the highway and stoped. The car would rev itself up and down while idling. It then started knocking really load. High pitched. And now it won't go above about 20kph and is knocking severly. It also smells like I am burning oil. Any ideas?

Sounds like a cooked motor. Start with a general check of: the compression, the coolant level and condition, the oil level and condition. A " smooth running" test would be great.
