1992 300D power loss=Transmission ?
I have exhausted myself looking for causes for my lost performance.
new parts... air filter, and both fuel filters I inspected vacuum hoses for possible leaks. I have plugged vacuum line coming from EGR valve and also placed a solid metal gasket for EGR just in case. I have noticed that the transmission isn't down shifting as I remember. Climbing hills is almost dangerous with no kick down unless I force passing gear. I havent checked the fluid level or color yet..the trani was serviced with Amsoil ATF @ 92k and now has 130K. Any comments or suggestions appreciated! PS I have searched the boards, and tried the possible fixes mentioned for loss of power. I havent been able to find any info on the transmission.

The year is important. Lots of people recommend it on the earlier ones, but starting with the 2.5 (1990 I think) the computer cuts the engine power when it detects a fault with the EGR.

Check the bowlen (sp?) cable adjustment.
Amsoil is not a recommend oil for Mercedes (or for any other car as a matter of fact.) Amsoil does not even have a API certification. jackd |

In section 0010/62 of the shop CD, it is said :
«The ARF system with vacuum transducer, switchover valve (as of Model Year 1992), ARF valve, air flow sensor and EDS control unit operates as a closed loop» So I guess that any alteration of a component in the loop will have an impact. For instance, the vacuum transducer of that loop controls the boost pressure. If the EDS detects something wrong, there's a good chance that he will kill the boost to protect the engine. That's theory. For the moment I can't verify this because I have a faulty transducer that generates a fault code and cuts vacuum to the boost pressure control.
