This '83 280SL Euro did not run for five years and I'd really like to get it working.

Symptom #1: At normal operating temperature I cannot idle above 2000rpm the rpms and vaccuum falling down. The same thing happens if I throttle it or if I open the air flow sensor plate manually.

Symptom #2: The car has no power. I can barely make it putter in 1st gear and I cannot accelerate it at all. When I try to accelerate the air flow sensor plate makes a popping sound.

To me it seems that this would be a fuel problem and that both of these symptoms are related to the same problem.

Therefore, I replaced fuel pump, fuel filter, checked and replaced all leaky air hoses, put in new spark plugs, replaced the injector o-rings, and cleaned the plunger from the fuel distributor which operates air flow sensor plate.

On the other hand, when I manually open the air flow sensor plate and trottle valve at the same time I can run up to to 4000rpm.

Has anyone had experience in this area? If so, your input and aid would be greatly appreciated.

Thanks,
