400SE engine choking, sputtering , no power
 

Today after driving out of the parking lot my 92 400SE began choking, sputtering and did not have any power. The engine acted like it was going to die, but I continued to “sputter” along at about 15mph. When I reached the traffic light, I put the car in park and turned the engine off. After restarting the car, the engine was fine and the car operated normal.

Anyone have any ideas what might have caused the problem and will it likely return again?

Thanks

What happened was most likely that the "limp home mode" was engaged. But as I have experienced it can be many reasons why. In your case, since the car behaved normal so soon again, it might have been a missed spark in the ignition and so to protect the cat, the computer turned it into limp mode.
If it comes back, go to your MB shop to get a diagnostic reading, since most of the information is stored in your car. However if the reason is a bad contact it can be harder to diagnose. Then you might find some clues if you search the forum under "limp mode". (This mode cut your revs at about 1.500)
Good luck!
