Bank 1 sensor 1 not switching. (passenger side front) Trying to correct for an overly lean condition. Look for a vacuum leak. Those engines were bad about creating a leak in the PCV tube that goes to the throttle body at the little rubber "T" that connects the 2 plastic pieces together.

Being way2old is why I need help from younger minds
