Hello,

I discovered that my 190e was running to lean (70%) Using the guides from this forum i was able to adjust the mixture to 49% which is perfect. She is running a lot smoother.

I still have a problem though. When i rev my car to 2500rpm the value doesn't go down 10% like it should. It constantly stays at around 49%

I tried another EHA valve and lambda sensor but it gave the same value. What could the problem be?

Thanks guys
