Help with my 86

odds are its the ignition module(in the distributor) or the coil. pretty common issue with fieros.

good luck with it!

Let me attempt to help solely based on my past experience involving my Fiero dieing, when does the car usually die?

I had the pleasant experience of dealing with two ordeals in which ultimately led to my car to die -- sometimes even in the middle of the road!

The first one was so darn obscure, ridiculous and unfathomable: the battery wiring of my Fiero had been burned/melted. The mechanic told me that the battery wiring, being close to the engine and all, had melted to the point where it was unreliable. Just before this diagnosis, my car would occasionally die and wouldn't start for days. I had gotten a new battery and alternator initially to address this problem!

The second one, the fairly recent one, was that my fuses needed to be replaced, with my ignition module and rotor, etc as they were all malfunctioning -- they somehow had became wet, I never understood how that turned out to be. My car would work fine and all, but when accelerating up a hill, my car would die -- engine revving seem to trigger it to die. The thing with this was that my Fiero would be able to turn back right on again without any problem.

Good luck!

Next time it dies, keep your eye on the tachometer while you turn the
engine over. If the needle moves a little and stays steady, your ignition
system is ok. If it jumps around or does nothing, it is your ignition
system. (very common).
