I've been having a problem long time ago. My benz does not have lambda oxygen sensor nor pin 3 in the x11 diagnotic socket thus i can't measure the lambda ration with duty cycle and now it is consuming a lot of fuel and hesitate when I accelerate  .
I wonder if there is any way to calibrate the mixture, similar as the 50% with duty cycle?
Thank you all! and sorry for my english |
1) Do you know if the oxygen sensor is missing, or was removed, or was the car produced without that sensor for Ecuador? [The absence of a pin in the #3 position suggests that it was produced without O2 sensing.]
2) Can you post pictures of the fuel distributor and air flow meter?
Yes, the mixture can be adjusted, just not as easily as with O2 sensing.
