Buckeye driver's bro, you have to give yourself like 3 car lengths in front of you because you know the person behind you is distracted and tailing your ass. We just had this conversation with a guy from here and when the subject of drivers ed comes up he's like you guys had to take class for your drivers license?
It's hard to say what damages you suffered especially without pics and no codes, but I think you'll be alright. Best guess for me is maybe your O2 sensor got knocked loose. But take it to the dealer and let us know what codes they read.
