my 99 w210 throwing malfunction code for 02 sensor bank1 sensor2???? but not always,
hello brothers, my 99 w210 e320 throwing a bank1 sensor2 malfunction code, the CEL is sometimes on and sometimes off , does it sound like a 02 sensor need replaced??? could it be because of the bad fuel??? maybe connector on the actual 02 sensor is loose???? anyone know where bank1 sensor2 located?? it's 3,2 l v6 , thank you

Passenger side
post cat. You need to either replace all 4 if never been done and at or over 100k miles they are due.
Looks like that one is failing.
Do all 4 and watch your mpg go up about 10%
Cheap 50bucks each and you just need a socket wrench with the proper size o2 socket. And a floor jack or ramp and some jack stands.
