Hi guys
I have a 2002 subaru forester xt automatic. It has a problem where it intermittently becomes sluggish, you can put your foot to the floor and it feels like there is no boost and then a few minutes later you put your foot down again and it goes like a cut cat. It happens no matter what the outside temp and changing gears does not effect anything and usually this happens when the car is hot. Like today in christchurch was 22 degrees and it was acting like two different cars one minute super fast next very slow. I have cleaned afm to no avail got no codes and was wondering could a bad front 02 sensor give you intermittent sluggishness without triggering a cel, sorry for the novel any help appreciated ta
