Engine Performance problem
2003 Subaru Legacy 4 cyl All Wheel Drive Automatic 130000 miles
My 2003 subaru legacy is hesitating a lot when I initially accelorate. It doesnt stop hesitating until I reach about 25mph. Sometimes it hesitates at higher speeds such as 50mph.
I changed the upstream o2 sensor after a mechanic told me that was the code it showed. Now it hesitates less frequently (maybe every 3 or 4 red lights), but still happens. Any thoughts on what it might be?
Any info would be great.
