1997 Pontiac Grand Prix

Engine Mechanical problem
1997 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 220000 miles

I have a 97 Pontiac Grand Prix with over 200K on motor It runs good most of the time. Check engine light has come on and since when I go to stop or turn and take my foot off the gas it stalls. I have replaced both O2 sensors (per auto part check) still had problem. When light is on car runs better and doesnt stall. Just took it back with light on and computer says EGR is the problem he reset light now we are stalling again. I would just replace the EGR if I was sure that is the problem but I do not want to continue just throwing money into this car. It is not safe to continue driving as it shuts off in turns and at stops. PLEASE HELP?

Its unsafe-The EGR valve will cause that problem-try cleaning it out and see what happens
