I have a 95 Mystique with the 4 cylinder. The car has about 186k on it and has been a fairly good car. It idles rather low, but at that mileage I don't ask much other than to run. My problem is that the car dies on cold starts (40 degress) after running for 30 seconds. I restart it and it will stay idling. I've done all of the work to it so far, so I'm fairly handy, but do not know how to check codes on the CEL. Any help would be much appreciated.
