I´ve got a puzzle.

Attached is a picture showing my w126, 420se in park. You see that the eco gauge is not fully to the left. From what I´ve read from this forum two things are possible

1. fuel-air mixture is not right. If so can you tell me the correct mixture ?

2. I have a vacuum leak. I am not a mechanic, rather a desk person with high interest in classic Benzes and this is my hobby car so if you could please advice were to start. For example is one thing more likely to be at fault rather than another. Any advice on simple methods for tracking the leak or "hot spots" would be greatly appreciated.

Best regards from Iceland
