I do think my wideband may be reading incorrectly. I have tested it all the ways Ive found.

I got a proposition for ya tho...lol...anything I can offer (cash/help on the car etc) to persuade you to let me test out your wideband on my car? Cause Ive been dealing with a "lean condition" thats unrelated to this issue for over a year now. Ive done everything I can think of to fix it. I was about to buy a new Innovate wideband but its kinda hard to spend $180 replacing something you dont even know is broken lol.
