mazda 3 Revving problem

[Cokekid1]

I have a 2009 Mazda 3 GTw/ Automatic, I have had a problem occur 4 times now. It seems now and then when I come to a stop the engine continues to rev, and it feels as if someone is pushing my car. It wasnt that bad to start with but the last time was crazy. I was coming up to a traffic light and i could feel that the engine wasnt slowing down. I stopped and noticed that the engine was at 3000 rpms. I quickly shifted into Neutral and the engine rpms quickly jumped to 5000. I have taken it to the dealer twice now and they cant find any error codes or anything that could be causing it. Help!!! If anyone has had the problem or know why its happening I would appreciate any input.

sounds like you are having a throttle issue, now without testing its impossiable to say but my primary suspects would be either the tps (integeral unit with the throttle body) or it could be the potentiometer in the peddle position switch
