I found the sensor on the driver's side of the intake unplugged, so I plugged it in. Now I get P2005 and P2012 before I even start the car, and I get P2006 after I start the car. The interesting thing is there is no way I "accidentally" unplugged this sensor. The previous owner had the Cobb Stage 1 V3.01 93 octane LWG tune loaded, and I never noticed any problems. Would there be any reason he would have had these sensors unplugged? I'm really confused right now. I'm hoping I have a simple problem, but I'm past my depth of knowledge. I though I was just going to be bolting on parts and flashing a tune.
