I've never had these problems with any car other than my Saab. Always, with other cars, the check engine light was an indication that the oxygen sensor needed to be changed. When I took my car in a few weeks ago, I provided the independent Saab specialist with records showing what had been done last year at the dealers to take care of the problem. This included replacement of the oxygen sensor on a trial basis, and then taking it out again when the check engine light returned anyway. The independent mechanic told me that an oxygen sensor for my car would cost about $400, which I find astounding. My understanding is that they cost well under $100 for other cars.
