I just put a different O2 in for the DS O2... no change at all... no guarantee that the "new" O2 is good though... Thougts?

My Lambses and KAMRFs keep changing for both sides. Am I crazy or do I have a problem here?

Thanks Toyman... I changed that out last night (10pm in the driveway...) and now the light is at least semi-intermittent... on ~60-70% of the drive in today vs 100% yesterday) so I HOPE it is good enough for emissions testing to pass... I'll find out either today or tomorrow...
