My CEL is coming on every few days now, but staying on for only a few hours at a time (2-18hrs.). Very strange, but the car still drives and sounds like a dream machine. Weird...

I'm going to get an oil change in 1,500 miles and will have the dealer plug it in and see what they can find. If the CEL is not on though, I fear they will not be able to find anything. I'll try to take it in when the light is on, but it goes out quickely. Hope the damn thing doesn't blow-up before I get it in.
