All of a sudden my idle stays at about 1100 to 1200 rpm. Might jump up to 1400
than back to 1200. Car only has 44,000 miles. Could this be a memory thing, or sensor?

It could be a bad idle air control valve. Could also be a vacuum leak. Check for codes and let us know. My guess is the IAC valve if nothing else changed. You should post this in the Northstar section. I would move it, but I don't have mod privileges here...

Thanks for the quick responce. Beats me what's going on, things are back to normal.
The next day we drove the car -things were fine. I'll still keep your ideas in mind.
Thanks again!
