Hey Gents. My 1999 Series II is being cranky. I changed both upstream O2 sensors hoping it would sort out, but no dice. I blew any dirt that may have been in the connections out with compressed air. I’m leaning toward faulty wiring. I’d like to get some opinions before I go trying to rewire a O2 connector for no reason.

 

I haven't seen faulty wiring yet on one of these. Most of the time its the sensors or something else wrong with the engine. Would like to see what you find

 

Here is some live data for anyone who can give me some input.
