My w211 is a little weird on low rpm,i have done a live scann of the oxygen sensor (b1-s1),and ita not oscilating,it is static 1.04 volt all the time, when i am driving its also on 1.04 volt

This is not right??

Plutoe

No that is not correct, by the way I thought your Father took your car keys away from you and you were nor riding a bike!!

Hehe,thanks for reply,where can the fault be,you have any idea??,its running rich??

Btw: you where close,some years ago, when i did not have the driving license, and my father was tired of the cops comming to our house, cause i drived so much illegall with my mercedes 123, he did unmount the driveshaft, and digged it down...hahah "true story"

Can the o2sensor be bad, bad i have no check engine light....wft can this be

Plutoe

Well I am glad that you never got caught--------the voltage does not vary because the sensor is faulty---replace the sensor and volia!!

I have changed the o2 sensor,but it still dont oscilate,if i remove the plugg,it goeso over 4 volt,and when i have the plugg connected, is like the old one was 1.04 volt,what can be wrong, and what causes the car to run so rich?

You are either getting false information from Ben's Wurld or you don't know what you are doing-----to clarify go to startek.info and lookup document GF0704P410301F(O2 sensor function) all will be clear!!
