Hi,
The throttle position sensor is electric, so I'm not sure what you cleaned. However, let's try to figure this out.
Does the check engine light stay on when the engine is running? Have you checked to see if there are diagnostic trouble codes stored? If not because this vehicle is so new, I suggest having the can-bus scanned.
CAN stands for controller area network. Basically, the different control modules are tied together via a few wires and communicate with each other. This type of scan will retrieve codes regardless of the module storing them.
Here is a link showing how it's done:

Amanda, you indicated in your first post that the engine won't stay running and it has a higher idle. Does it stall at idle or while driving? A high idle usually indicates it isn't stalling at idle, so I just need a little clarification.
Next, if it has a low idle and stalls, it could be something as simple as a vacuum leak.
Here is a link that explains how to check:

Let me know.
