So I have been having some troubles with my car and so I hooked it up to a scanner and read a bunch of codes and pretty much determined my O2's were bad. My Long Term Trim levels were way out of wack and also my Oxygen Sensor test for the Emissions Testing isn't ready but my question for you guys is I put my car up on my lift today and switched the drivers side O2 without much problem but when I got on the passenger that was a world of TROUBLE! I fought for about an hour trying to get it out with no success. Do you guys have any clues or tips to help me get it out. Any suggestions are welcome thanks guys
