Exhaust Gas Recirculation Circuit Range/Performance

no one? its on my sisters 99 saturn sl1

Its the egr valve or controller related to it. could be carbon build up on the valve, or it could have been stuck, or strange computer error

i know its the egr valve etc... just wondering how to fix it

Well, you have to figure out if the egr valve or controller went bad, or if it's just clogged with carbon so it can't operate properly.
