1991 Pontiac Grand Am Q&A
1991 Pontiac Grand Am Question: would a defective egr valve cause your engine to quit at highway speeds?
i was driving home from work on the parkway going 65mph when the engine lost power and quit.when i tried restarting it would just crank and sometimes backfire thru the carburetor.i got the car home did some checking,the engine will start without the egr but the rpms soar. - grandamguy
