Hello,

Using a multimeter i was able to see that my 190e was running to lean (was fluctuating between 67 - 70%) so i adjusted the mixture to 49%. She is running a lot smoother.

Problem is, the value doesn't change at all when and constantly stays at 49.2% even when the car is revved (above 2500rpm) The value is meant to go down by 10% when at 2500rpm. The lambda sensor was replaced recently.

What would this indicate? Thanks guys!
