Benzmac, Jim, 420SEL & Rudy: Thank you for your pointers. Sometime next week I'll leave my car with my local, independent M-B mech and have him look into all of your suggestions. As I wrote, it is more of an annoyance than a real problem and since the car runs fine otherwise, I guess I can put up with it. I used to have a 1967 250SE (Euro) with mechanical fuel injection, same as the 190SL. That little old six-banger purred like a kitten. It had its own little idiosyncracies, but it was a very reliable car.

Donnie (Benzmac): Thanks for the tip on the A/C aspirator fan. I still haven't taken the plunge to look for it behind the dash area. When I finally do, I'll report on how it went. By the way, does a faulty A/C aspirator fan make a whiny little noise that can be heard only from the overhead console grill? How does the noise travel up from behind the knee bolster to the overhead console? Through the hose?

420SEL: Thanks for the suggestions, I read your other posts, on another thread, about your 420 rough idle. If your mechanic diagnoses the problem, and fixes it, let me know. I had read someplace here that someone suggested putting a silicone seal around the injector seals and that fixed the vacuum leak and the rough idle problem. Have you tried that?

I will keep everyone posted if, and when, the mechanic can diagnose and fix my problem. In the meantime I'd welcome any other suggestions from the rest of the gang.
