I recently changed two clogged injectors and it got rid of my multiple misfire (P0300). I also changed the catalytic converter and the P0420 was gone for about three weeks and is back now, along with the O2S12 and the P0442. A little help with this would be highly appreciated. This car has been driving me up the wall. I'm dam near broke with this Malibu.
