1994 e220 coupe misbehaving

I have a 1994 e220. It has only done 35000km, so inexcellent condition, but it is misbehaving.
When the engine is warm, between 2500 and 3000rpm the power fades. Engine does not run rough, just fades away. Picks up again at about 2000rpm, and the cycle repeats itself. Once over 3000rpm runs more smoothly.
Took it to local mercedes mechanic, and he stuck the computer analysis on and it said throttle body. This and wiring harness both changed, but no difference. Then changed the ECU, and again the problems persists.
Mechanic now scratches his head and says ' I DO NOT KNOW WHAT IS WRONG'.
Any ideas at all would be appreciated.
Many thanks.
