This morning my car listed above held at 4,000 RPMs while on the brakes. I had to throw it into park to avoid an accident. After that I couldn't get it out of park. Tried and tried but it felt like it was stuck. I finally got it into drive after trying many times. Anyone have any advice? Or just know if i should get a new car?

A new car is your choice, but if you want to fix this one. Make sure the floor mat is not holding the gas pedal down. Then I would make sure the throttle cable is not holding the throttle bore open, if that is okay, I would try swapping out the IAC motor. Also, you could have a vacuum leak. Use this guide when the engine is cold only:
