What should you do if the shop says your 2000 Metro with 155k miles needs a new cat converter and 02 sensor but that's expensive and it runs fine?

Answer 1

My sense is that these components last somewhat longer than first anticipated, probably because of the leaner mixtures we're using, and the no-lead gas. It can be expensive. But you probably could change out the oxygen sensor yourself. It's usually accessible, and it ain't brain surgery. The converter is another matter. Good Luck i had a metro with 250000 with original convertor and 02 the convertor is built into a section of pipe you get the whole thing for 150$ and replace it with four bolts and believe it or not the bolts usually are removable without having to use a torch
