What does this code mean?

 

P1106 O2 Sensor Circuit (B2-S1) Voltage Too Low - Air Leak A
Your pre cat 02 sensor on the drivers side cat is probably shot. If you dont know how long the code has been stored, clear it and see if it comes back. If it caused a CEL, thenits probably like i said. DED.Its the first 02 sensor in the cat, being the sensorclosest to the engine block/manifold. Or maybe its not in a cat, but in a down pipe. Whatever... You know what I mean. First 02 sensor in the exhaust closest to the engine on the drivers side which is bank 2 (B2). Your V6 engine is shaped like a V. The left side of the V (passanger side) is B1 and the right side of the V (drivers side) is B2. Sorry for the elaborate explanation.

 

Had the same thing a year ago. Turned out to be a hole in the exhaust right around the O2 sensor. $15 weld job...good as new

 

could this be causing my engine to misfire? I have two cylinders misfiring?
