Today on the way home from work, Buzz (my yellow Fiero) started missing like one cylinder wasn't firing. Then a loud rattle started, like the vibration from missing caused something to break loose in the exhaust. So I pulled into a parking lot and got towed home. I know from experience that running with one cylinder not firing will burn out the catalytic converter, so I pulled off as soon as I could.
I'll be driving the red Fiero until I figure out what the trouble is and fix it.
