Hmmmm thanks for the tip. I just checked the air pressure this evening, after letting the car cool down for a few hours. I have 31 PSI in both the fronts and 33 PSI in both of the rear tires. I just made a 600 mile round trip over the past 5 days. On the way I think I the light came on once. After I arrived and made several short trips around town over the last few days the light came on periodically. On the way back home the light came on and stayed on for 100 miles or so. After stopping at a gas station I didnt see the light again today. Weird. I did experience the ignition locking up on me again, in the sense that it wont let me turn the key far enough to start the car. I'm going to see if a buddy of mine has an OBD reader for these newer cars.
