Have 95 legacy,2.2,4eat transmission,225/70/14 all terrains
have had the knock sensor code for a while,but here's the issue.Drove to the beach,got 22.7mpg on the way there.drove all week on the beach etc. On the way home I only managed 14.5mpg,and it felt like it had no power whatsoever. I happened to run though a bunch of water at the beach,so I figured I got my o2 sensors wet(it would shake and shit when I went through and for a min after the water) so I replaced it. Made it run better,but still getting terrible mileage I average 15ish.now im getting a erratic idle and feeling sluggish at lower rpms. Any insight is appreciated.
