Not sure what a hard code 8 means for a Festiva, but you can probably find a Haynes or Chilton Manual at your local library and get some understanding of the problem - whether you try to fix it yourself or have a mechanic fix the problem. I had a similar problem with a 1987 Cavalier and it turned out to be a bad catalytic converter. - Good luck. have you tried changing the spark plugs?
