Re: 98 Firebird Evap test
If you don't have any trouble codes set, there shouldn't be any issues with all the parameters running and passing. Yes, at times it does take quite a while for everything to run, but it shouldn't take 400 miles. Usually a bit of stop and go driving and then some highway driving will get everything to pass, if there are no other issues. I'd recommend getting it scanned again just to see if any codes are present.

That code is for the catalyst efficiency, which basically means you need a new catalytic converter. Get it replaced, clear the code and then drive again until all evap tests run and pass, then you can take the emissions test again.
