Just want to remind you before you decide to work on it yourself, that it is still under the 5yr/60,000 mile basic warranty and unless you have installed mods on the engine or removed emission components, any issue will be under factory warranty. If you try to repair yourself and cannot and there is evidence of you going into the engine, they will not cover the repair under warranty as it you will not be able to prove that whatever you did, did not exacerbate the issue. Possible causes are vacuum leak, air intake leak, electronic throttle body, or even a low voltage issue due to charging system fault. The first step is checking vacuum hoses, air intake tube and intake manifold gasket for sucking in air and correcting as needed. If ok, then throttle body needs to be tested with scan tool for proper TP1 and TP2 sensor operation. If ok, test charging system Thanks for using Just Answer and letting me help you. I hope I provided what you needed. If you find more help is still needed, let me know by listing out any remaining questions you have on this concern. I hope the remainder of your day is well.
