  1. Txtab: I swapped all old o2 sensors to the new pipe. I know it's not the best thing to do, but I don't want my dad to spend tons of money. I eventually replaced bank 2 sensor 1 and I replaced bank 1 sensor 2 which had the high voltage. I cleared the codes, drove the truck for 25min no CEL popped up. So we'll see I guess. Carnau: I will be heading back over to his house soon, I will check those fuses and let you know anything I find.
  2. OK, so I'm trying to fix my dads truck so it can pass emissions. He has a 2008 GMC Sierra 4.8 1500... We bought a scanner tool to make things easier. But it's throwing out codes like candy on Halloween.. at the present time I have replaced the EVAP canister, I have replaced a bank 2 sensor 1 o2 sensor. I have replaced the whole down pipe with new Walker catalytic converters, I have cleaned the throttle body and MAF sensor.. Now after I installed the new Y pipe with converters it threw these codes at me: P0138 P2273 P2270 P2271 Can anyone help me please, I have the end of next week to solve this nightmare.... please note: I have only replaced bank 2 sensor 1....
