Hi!
Just fired up my 1999 986 2.5 after almost two years in the garage. It was fine when I parked it. On first startup the red light next to the temp gauge started flashing, and the CEL came on. Not flashing. I checked the coolant, and found it was a little low. Just under min. Added some coolant, changed oil and filter, and both lights were gone. That was yesterday. Today the CEL light came on again. Car pulls strong, and the oil looked fine. No water in it, and no bad signs in the filter either. Will hook it up and read the codes, but what do you think is the most likely cause of the CEL?
