I have done several things with the car over the years, but the things I remember most significant were, the most recent, I had a new fuel pump put in.
It was sitting for about a month and It did not start up when I went to it again. I had it towed to a mechanic, and had to have the fuel pump replaced.
The car has always had idle problems. For example, if it's too cold or hot out, or if I'm driving in heat in traffic, or for no reason at all, the car will die when I take my foot off the gas and try to brake. The car seems to idle so low, it just dies. Sometimes on the freeway! I have taken it in too many mechanics, and they say it's just a little dirty in the carburetor, which they blow out (or however they clean it) and give it back to me. It never seems to die on them. It only happens here and there, but it's an ongoing problem.
About 3 years ago I had to replace a C.B. Boot. I'm not sure what that is, but it was cracked.
The heater, even when turned off, will emit a slight heat (unless it's in circulation mode), so it gets pretty hot in the summer.
It also seems to be slightly slow when getting up to speed on the freeway and especially on steep hills or mountain type hills.
Other than that, the car has run pretty smooth.
