Typically from insufficient heat, often caused by running long tube headers and/or cams with high overlap. There are also tuning moves that can help or hurt the situation.
If the integrated 02 heater isn't working or working properly, it can also cause it. You really need to scan the car to see how and when they're switching to get a better idea of what's going on.

AC Delco oxygen sensors
OK. I found several places on line that have them. I'm going to replace both front ones and see if that takes care of the problem. I'll let you know.
Thanks!!
