Rough running: is this linked to O2 sensor? 200

I'm sorry I'm not familiar with the FB version of the B230, but do you have Bosch or Regina EFI ?

I know when I killed each of two O2 sensors on my '89 240 (Bosch), it did run rough, but not when cold, only when it was warmed up.

The Regina uses a Tatania O2 sensor, which is a whole different animal, so I don't know that any experience with one applies to the other.

Are you sure the O2 sensor light (My cars don't have that)comes on because of an actual error detection and not just by miles like the Service Engine light on my 740 ?
