Back in the 1990s, I had a 1987 Toyota Camry that had 210K miles, even in 1997. It ran very smoothly, but it was low on power. I never thought much about it at first, but it got worse. It got to where the "check engine" light was illuminating when I was on the freeway. I am not sure who told me or how I found out, but we ended up putting on a new converter and that fixed the problem. The converter was almost completely clogged. After that, I had to get a new muffler, because it was bad (although I would have never known, because no air was making it back there).

I am amazed at the power that the car had after that. I regret selling that car. I sold it in 1997 to a older gentleman, who still owns and drives the car. I know, because I see him driving it from time to time in a area of town that I have to go through frequently. I have not seen the car for a few months. Perhaps he sold it, or moved away?
