My 400E had very similar problem before, at highway speed, if I kicked down for max accerleration, the rpm wouldn't past 5000 rpm, as soon as rpm reached 5000 rpm, the rpm went into a kind of violent oscillation. ABS and cruiser control also didn't work.

I found out one of 4 10A fuses in the black computer box was shot, after checking the schematic, I found that fuse protected throttle control module and ABS module.

A 50 cents new fuse sloved these 3 problems, the computer box locates at the passenger side just behind the firewall.

Still missing the days with the Benz, it kept me busy.
