The other day, I got on it a little bit hard avoiding an accident. Immediately after it started misfiring, the check engine light was flashing and the stability light, (The car with the squiggles) not the the stability off light. I went 2 blocks to work no smoke so I shut the car off, turned it back on, and everything was fine. Drove home after work (30 miles) no issue. So then the next day when i drove to work everything was fine until I pulled up to a stoplight nearly 30 miles later, and then it started misfiring with the engine light and the civility light on, I shut it off again. Started up and everything was fine. I don't know what that is.
