emissions test
I have 230E (same engine 190E 2.3) with a very poor milage but good power and acceleration. I went to benz specialist and he adjusted the mixture. Now the power of the car has been reduced a lot. Below are the emmsions test before and after the mixture adjustment.
Test before After
CO 5.4% 1.8%
CO2 11.2% 13.5%
HC 268ppm 753ppm
02 0.08% 0.07%
NO 0 0
Lambda 0.841 0.921
Please advice wheather these values are correct or shall I ask the technician to increase the power. But is there a way to get good milage with good power (what are the optimal values).
