Pre-Cat Fuel Trim Lean AND Rich?!
I have a '06 3.0i. It was about 20 degrees F. The SES light came on and has been on for the last week. I ran it with an Actron Scanner...two codes showed up:

P1092 Pre-Catalyst Fuel Trim Too Lean Bank 2
and
P1093 Pre-Catalyst Fuel Trim Too Rich Bank 2

Why is it both? I have an appointment with the mech next week, but was wondering if it was okay to drive as it is now. Any help is appreciated. Thanks!
