The manual said is was a problem with the "Computer Command Control" (seriously) and/or the oxygen sensor in the exhaust system. This was accompanied by major stalling at toll booths. By the end of the trip the stalling had gone away and the car was wanting to race across the parking lot at 45mph without any foot on the gas. So I took it to the shop where the fixed a perviously undiagnosed exhaust system leak and turned down the idle. Driving to work the next day, the light came back. I was told that the automated diagonstic routines could find nothing wrong and I should wait until something broke, whereupon they could fix it. Currently the light comes on after about 5 minutes of 60mph or above driving, stays on for 5-10 minutes, and then goes off again. The cycle then continues with variable intervals. The cycle does seem to have something to do with speed, since I have never seen it come on below 55 and it always goes off when I get off the highway. However, it also goes off spontaneously if I just ignore it and keep going 65. Gas mileage is still about the same as it used to be. Does anybody have any idea what the problem is? This has been going on for 3 weeks now, and nothing else has happened. However, I am still paranoid that something will break, leaving me stranded in the middle of the night on some deserted stretch of road.
