ampiifire Posted February 23, 2009 Report Share Posted February 23, 2009 because i didnt have the foresight to replace it when i was litterally kneeling in the engine bay drilling holes through the exaust flange with the engine out a few weeks ago. got it running and im throwing codes for the rear o2 sensor along with a random misfire [p0300]. i am hoping one will fix the other.. be we shall see. anyways, having a very hard time accessing it because of the two heater core/recovery tank pipes that piggyback the bank 1 valve cover all but completely prohibit access from above. cant seem to get my o2 socket on from underneath either because even though i can touch it, i cant get a thumb up there WITH a finger. has anyone replaced this nightmare before? or does anyone know what the FSM says the procedure is? i am downloading a shop data program illegally (shhhhh) but its going to take like 2 more days to finish the GM cd's. any help before then would be very much appreciated :] Link to comment Share on other sites More sharing options...
