hi i recently noticed this but every time my prelude stops it would "self-rev" itself. i have had this car for about a year now and its a great car. so does anyone have any ideas on whats wrong?

sometimes called the bouncing idle

check out your IACV..a possibility

There can be many causes for bouncy idle, but the most common cause is air in your cooling system. Have your refilled your cooling system recently, or do you have a coolant leak? It's important to bleed the cooling system to get all the air out.
