w124 200e lacking alot of power

[PeterClark]

Hi I have a Mercedes w124 200e manual 1992 that has lost a lot of power to begin with the engine lost power and would not rev right below 2000 RPM but as the engine got hotter it would raise the RPM that it would become fine again. Now it has lost power right across the Rev range and suggestions would be much appreciated

Take it to an MB specialist. There are loads of possible reasons - blocked cat, loss of compression, bad fuel pump, bad ignition module, distributor cap, etc, etc

Maf sensor possibly

Don't think the early cars had one

It could be many things but on a 102 engined W124 I would first take a close look at distributor cap and HT leads before looking at fueling.

Didn't have a lot of power to start with - must be dreadful !
