Our local Benz mechanic told us the ALDA diaphragm is bad - has a hole in it. Someone else told me it's 'supposed' to have a hole in it...(?).

This is the car which, when I take the throttle linkage in hand, and run up gently, doesn't really throttle up until the ip linkage is 1/8" or so from the full-open stop. because of this, I have to drive around with the pedal to the floor most of the time - unless I'm slowing down. And any typical hill on the highway is always a drop a gear and hope she'll maintain 45 mph thing. After 3 years of trying, I have to say I'm ready to fix it, or sell it

and the wife agrees...
