why does it do this?
 

I went to play in some mud/ puddles not to long ago and of course big puddles are to hard to pass up so I went through it.. then the car just started like reving then stopping and again for maybe 10 min while I was in nuetral and when I go to take off it kinda putters instead of accelorating the reving only happened after hitting water the puttering happened this morning actually and I was confused, anyone know what it could be?

I'm not really sure but I'm guessing you got some water on some electronics. It kinda "shorted" maybe? and then once it dried off it went back to normal.
