OK, here is the deal. My car is bone stock and always has been. I got the dreaded CEL approximately 2 months after buying it, approximately in March of 2007. I took it in to the dealer and the mechanic said they had been getting a lot of those, something about a valve needing a slight adjustment. Since then, no CEL's. I have only taken my car in 2 other times for warranty related service since: 1. Engine mount replacement bolt/mount, and 2. That emissions recall, something about the swirl valve. The light came on driving to work today seemingly at random. And yes I know I can get it checked out at Autozone and it is hard to say what it is without knowing the code, but any ideas? Also what is the length of time stuff like this is covered under our warranty? I guess I will be calling for an appt. today. I am going to check if it is still on the next time I start my car. I will keep everyone updated. Thanks.
