In other news: Last week the "check engine" light in the car came on, which turned out to mean that we needed a new oxygen sensor. We got the rear brakes done at the same time, for a total bill of $475. That was Friday. Tuesday, the "check engine" light came on again.
I took the car in this morning. Apparently, the car's computer doesn't like the correspondence between the front and rear oxygen sensors, and suggests that the catalytic converter must be broken. The guys at the garage can't seem to replicate the problem: they say both oxygen sensors are reading precisely what they should be. They don't want to replace the catalytic converter unless there's more evidence of the problem - which is nice of them, considering that it would be a $600 repair. Apparently, there's a possibility that replacing the oxygen sensor just caused a temporary glitch that won't recur. So they re-set the "check engine" light, and told me that if it comes on again I can pretty much assume that the catalytic converter needs to be replaced.
Pleasantly, they didn't charge me for the diagnosis. They also went out of their way to make sure I understood that a malfunctioning catalytic converter won't damage the car or lead to a breakdown - it will just mean that we'll fail emissions. I don't want to contribute more than my fair share of air pollution, but it's still nice to know that we could put off such an expensive repair, if we have to.
