Tim - Thank you! We plan on taking it to Auto Zone this afternoon to checkout the codes.
Dmax - I've had the car for 4 years, had to add coolant once before, but just a little each time. Actually this morning, I lost power when the heat was off. We thought it was because of the heater but this morning that theory proved us wrong. We have a book that has what the codes mean and once we get them, I will post them. Thank you.
I know I have limited information here, I was just trying to get ahead of the game.
