Join this channel to get access to perks:    / @robertdotterer   Today we have a 2005 Land Rover LR3 4.4l that they said multiple attempts at fixing it did not work. They said it misfires and runs rough. Also I lost the footage for the oxygen sensors but it was a blown fuse, somehow I lost the part of the video but I left what I had to help someone.
