That problem would normally trigger the wrench light in the instrument cluster.
I suggest you scan the ECU for fault codes and go from there.

There is actually a weird exhaust note that comesome with it occasionally too. It only lasts while I idle but when I start driving it goes away. There is also a high pitched whining noise under the hood when I Rev on it while idling and you can hear it when you get to higher RPMs while driving. It sounds do just like a supercharger, but I don't have one.

So another clue is the whining noise. An alternator or belt pulley bearing could easily make that noise.
And we know an alternator can kick up some goofy codes.
Also check the PS fluid level.

PS fluid?

yes, PS fluid. Since everyone's interpretation of noises can be a bit different, gotta cover all bases.
Lack of fluid will make that pump whine very noticeably. Turning the steering wheel back and forth will make it change pitch. If it doesn't change, then that eliminates the pump as the noise source. If it is full, and the noise still changes with steering wheel movement, then the pump is going south.

Make sense now?

Lol. I mean, what is PS? I'm not to good with abbreviations.

Starting to get worried. I just shut the A/C off about five minutes prior. It seems to get a lot worse when the A/CHANGE is on.

Does the engine rev up during these problems and the car just won't go or does the engine not rev up? If the engine revs but the car won't move, that's a slipping clutch. If it doesn't rev up and simply doesn't respond, that electronics related.

It may be a problem with the TPS (Throttle position sensor) or switch by the pedal that controls the Throttle by wire system. I think someone else mentioned it. IMO take it to a dealer or reputable shop versus trying to just throw parts at it. let them diagnose it then fix the problem yourself.
