My CEL turned on yesterday on the way to work, I wasn't driving hard was granny style driving it trying to make better use of my gas. Anywho I haven't had time to go get the code pulled, but tonight driving home from the gym I noticed the CEL was turned off. Random right? I didn't disconnect the battery so I don't how it went away. Has anyone had their CEL just turn off? And can I still go to a shop and get the most recent code to see what it was; or maybe it's not even worth it if it turned itself off.

Thanks for the help.
