My ef sedan is an automatic the problem is when I'm at a stop light or sign then rpms go down to about 1k and then drop a little up from 0 and go up to about 11k and it does this until I hit the gas and go

 

11K? Holy crap. My car was having idleing problems and it turned out to be a bad ecu. It would idle down and up and rev to the moon as well.

 

11k wish my car could do that...

I think he means 1100 .

Anyways, it sounds like a dirty EACV. Are you getting any codes? I'd try searching on how to clean the EACV and give it a try, it should help.

 

yeh I think he means 1100

 

Sounds like a FITV problem. Take the plate off the back of the FITV and see if the plastic nut inside has come unscrewed. Screw it all the way in.

 

I had the same problem, my throttle body needed screwed tighter on the intake manifold.
