1987 Firebird Formula TPI 350 stalling out.

OK,
O2 sensor was cracked and ended up breaking on me. I could hear the exhaust leaking by it so I changed the O2 sensor. Now? I start the car and unless I throttle it the car stalls. Even cruising down the road if I let off the gas the car will stall out? Ran fine before this O2 issue. O2 sensor installed was identical to the one removed. When driving its fine just can't let off the gas.
Any suggestions?

Remove power from ECM to clear codes and try again...

Just wanted to update this post by saying that removing power to the ECM worked as you indicated.
THANKS!
