Pull the SES code from the computer before you do anything at all. Dont start theorizing until you know what the problem is.
Your engine will not run right with the O2 sensor deleted, and you only have the 1 on the drivers' side.
If you have an O2 code, then the sensor or its connection is bad, in nearly all cases its unrelated to removing the catalytic converter.

If the sensor is before the cat there is no reason removing the cat would trigger a code. Newer style multiple O2 sensor vehicles could throw a code as the after cat sensor is designed to trigger a code if the cat stops working. But if your car is a single O2 sensor sytem thats not the issue, but Vader is right, pull your codes first, then see what needs to be addressed
