Not in my cars. Whenever I have a problem I always rule out the basics; 
low oil level, coolant low, need of a tuneup, etc.

I always try the least costly solution and move up.

I bet your primary O2 is done. With the CTS, the basic symptom is that 
you should notice that your temp gage sits a little lower than what your 
normally see.
