P1131 means that the right side (passenger) sees too much air and is letting you know about it. Most people are the slap a o2 sensor on it, but sometimes this can be caused by as simple as a vaccum hose unplugged. Would take actually looking at it to determine the cause on the code. Some I've seen have been intake gasket leaks, some o2 sensors, and one K&N air filter that set this code.
The check fuel cap light is on. IF riding around for a few days don't take it off, you have a major air leak in your gas vapor storage unit (aka Evaporative emissions. Or that vapor you see when fueling your car sometimes)
It has to test the system for it to go off or a scan tool has to take it off for you. But cars usually won't pass inspection unless all the test the car runs itself have passed. So you are definitely looking at a shop to either fix it or spend enough money to pass it for another two years.
