    start by cleaning your MAF sensor with CRC MAF cleaner. The codes you are gettign are for bank 1 (drivers side) O2 sensor pre cat. I will clean the MAF and if it does go away then try swapping the sensor with the passenger side. If the code follows to the passenger side then the sensor is bad. Have you inspected the wires to make sure they arent pinched or melt down?

    Cleaning MAF helped, but I'm still getting the code. Anybody know what real-time pressures i should be seeing for the LS2 MAF? Trying to narrow it down between if the maf went bad or if its the pcm going bad or if its an electrical problem.
