Fiero sensitive to the weather? (Page 3/3) 2.5 APR 20, 12:31 PM What year miles and model, and when was the last tune up? thesameguy APR 20, 12:48 PM Here in Sacramento my Fiero goes from 15F to 115F every single year. It's never given me problems and is probably one of the best old cars I've ever owned in terms of weather handling. I don't hold '80s fuel injection systems very high, but I get consistent results from the Fiero. I'd definitely say it's capable of good behavior.
