    This is a pretty large subject. Here is an article I wrote about for 1 of the more common Evaporative System Codes and there are several. What is the Check Engine code and please be specific.

    There is no check engine light that comes on. There is a fuel cap light that comes on. The transmission seems to lose the first two gears when this happens
