Unlike a surge which comes out of nowhere, my 380sl pulses at most speeds. I've replaced fuel filter, fule pump and oxygen sensor. I live in small town Alaska and it's now beyond us. What can I check next?
Thanks much.

Sounds like it could be the fuel distributor. They develop leaks in the diaphragm between the upper and lower chambers. The age of your car makes it a prime candidate for replacement. Not easy to check. Verifying non-linear and unbalanced fuel flow requires special instruments to check. Its usually the last thing to replace since it is expensive. I have had to replace 3 in my fleet so far.
