I am sorry to hear you have this problem. Not an easy thing to be honest.
So before we go forward, let me tell you what that code actually means.
A Code P2191 means that the engine is running lean, only on one side.
It is officially called: Trouble Code: System Too Lean at Higher Load Bank 1
This might not cause a lot of problems in the short-term but in a few weeks or months, Eventually damaging your engine.
However, solving this is not an easy thing. Since there are so many variable you have to look at.
Some possible issues that might be causing code P2191
1. A leak in your car's exhaust
2. A problem in the PVC system
3. A fuel injector that is leaking
4. High fuel pressure condition.
You can start to check these one by one and let me know what happens

Thanks for the info I took it to a mechanic yesterday that fix my catalytic converter. He suggested that I take it to the dealer because he has a feeling it's something to do with my injector. So I have an appointment scheduled for Friday I'll keep you updated
