01 9-5 3.0 another coolant temp sensor problem?

Hi all,
I am fairly new to this site. I just got an '01 9-5 3.0 wagon. I love the car. Anyway, the hot water bypass valve sprung a leak. I replaced it with no problems except now, while I am driving the engine temperature gauge sometimes bottoms out. The A/C goes down and the engine light came on. If I turn off the car for 30 seconds and restart, all is fine. I can run it for 50 miles or 5 miles. No telling when it will happen again. Is it:
air in the system?
bad temp. sensor?
bad t'stat?
or something else. Thanks any help is greatly appreciated.
