Check Engine Light, 2002 Forester
I have a 2002 Forester with lots of km, around 148,000. In the last six months, the Check Engine Light has shown a pattern of coming on for a few days, and then mysteriously going off again. Does anyone have advice on whether: (1) this on-off phenomenon is a common occurrence? (2) the check engine light indicates a serious problem? (3) getting a garage to do a diagnosis is expensive; and (4) it is worth fixing whatever problem it might indicate on a car that is approaching 150,000 km.
With that one worrying issue as an exception, my Forester is still running just fine, and I am happy with it, but i do not want to spend a lot of money to fix a car that is so old.
