Good stuff - keep an eye on it for the next while. For the P0128, keep an eye on the temp gauges - they will blank out or drop to zero, and the a/c will be disabled if it comes back. Using the SEARCH tool at the top of the page and searching for P0128 will give lots of tips on the thermostat problems that a few have encountered, and will also lead to a how-to on replacing the thermostat yourself (which will save you serious $'s compared to what the dealer will charge you).
