I have a 2006 jeep liberty and a few months back I had the bank 1 and 2 o2 sensor code come up. I replaced all 4 with bosch o2 sensors, i've since read that they might not heat up fast enough on start up and I could get a code thrown again.. but no problems so far. Shortly after their replacment the jeep started having an occasional hesitation where it would feel like its running only on a few cylinders. I changed the spark plugs with copper tip ones ( there seems to be some discrepensy on the forums about the proper plug ) and I gapped them correctly to the spec under the hood. The problem still persists and I'm a little stumped. I was thinking perhaps fuel filter? but I see that it is a pain to get at. and this jeep only has 70 000 miles on it. Could the non OEM o2 sensors be causing this issue? Please help. I really don't want to end up stranded!
