Engine Performance problem
1999 Subaru Forester 4 cyl All Wheel Drive Manual 235K miles
The check engine light is always on. It used to be intermittent. The horsepower seems to drop intermittently to the point where I have trouble accelerating. Then it's fine. I purchased a code reader but can't find the computer plug under the dash. Can anyone help me find this connector or tell me what could be wrong with my car?
