*I apologize if this is not the right section to post this, im kinda new

Anyway, my car has been having some RPM issues today. Everytime i let go of the gas pedal, my rpm would drop rather fast. It kinda fluctuates going down. Like it would go down fast, stop for a half second and go down some more. I dont get it. Its an automatic. The car also has a different feeling driving it. I have a video included below about the revs.

Watch what the RPM's do at 17 seconds when I let go of the gas pedal. Also watch at the end how the RPM's would just go up and down while Im not doing anything.

Somebody please help.

 

I don't really hear or see anything wrong. Check your codes and clean your TB. Maybe it's more your feel then reality...
Any mods?

 

My 06 does this rev matching thing when im slowing down. Sounds cool as hell.
