elliott.daubney23 Posted September 15, 2021 Share Posted September 15, 2021 Hi. I’ve a 2003 Subaru Legacy auto EJ2. As soon as I get near 2500 revs it starts to stutter and then then drops a gear and shoots off. I’ve changed the o2 sensor and that helped for a week and now it’s back. It’s been driving me mad. Any ideas Link to comment Share on other sites More sharing options...
