my 1994 saturn sc2 stalls when i come to a complete stop...any ideas?

no, not the o2 sensor.i would look for a vacuum leak. it is the most common reason for stalling on these units. Roy

This may also be a bad EGR valve. You can remove it then turn it upside down and spray carb cleaner into pintle hole. Allow it to soak for a coulpe hours. Then pour out any carb clean left inside and clean pintle tip with a green scrubbing pad to remove carbon. You will need to clean off the gasket surface and buy a new one. Its held on by two 10mm bolts and has one connector. These going bad is very common and does cause a vacuum leak type of complaint as Roy had said.
