Loss of power, rough idling, code p0171 Sign In

Hello, I was driving my car yesterday and while going up a hill I revved the engine really high and than imidiality smelled something burning and lost most of the power to my car. Now it vibrates a lot when idling and has a hard time accelerating and increasing rpms. It now has an error code p0171 which I read means a bad air fuel ratio. I read some possibilities and have some ideas but was wondering what you guys think. One thing I should mention is there's no burning smell now. Only initially right as the car first started acting up.
