Car Running Rich!
Hey Tech or anybody! I changed both O2 Sensors with Bosch ones and it still is running rich. It reads B1S1 Fuel Trim 99.06% and B1S1 Equivalence 1.999 LAM.
Any ideas what it could be, vacum lines maybe? Thanks for any comments.

I diconected the battery for 1/2 an hour and it's still the same. I ran the onboard test while I was driving and it came up like this,
Continuously Monitored Systems
Misfire-Complete
Fuel System-Complete
Comprehensive Component-Complete
Non-Continuously Monitored Systems
Catalyst-Not Complete
Evaporative System-Not Complete
Oxygen Sensor-Not Complete
Oxygen Sensor Heater-Not Complete
When I finished my short drive, all said Complete except for Catalyst and 2 Pending Diagnostic Trouble Codes, Ignition System Misfire Code P0333 Knock Sensor 2 Circuit High Input (Bank2) which I've had before and Fuel And Air Metering P0134 O2 Sensor Circuit No Activity Detected(Bank 1 Sensor 1).

I got home and hooked up the laptop and the Mass Air sensor is at .40-.60 lb/min. at idle. The code for the Fuel and Air Metering went away, car runs stronger now since I installed
the new O2 sensors but B1S2 Fuel Trim is still at 99.06%. Do you think over time it will correct itself or is it maybe an vacum leak? On our trip to St. Louis last week, we got 33.28mpg on the highway when I calculated it at the pump, I thought I would get bad milage running rich. Oh, and when I got home this evening the P0333 code came up again, but no check engine light, said I was at 71% load at like 4700rpm's.
