Recently has SES light indicating bad O2 sensor (rear bank, upstream). Replaced sensor and no more trouble code. 1 week later noticed my wiper fluid didn't work. Washer fluid tube had melted. Replaced it with a new one and it did it again within a week. Is the rear bank running lean and thus causing a heat issue? Should I replace all the O2 sensors? I don't want to replace the fluid hose again just to have it melt a 3rd time.
