sounds like the idle charge motion plate motor might have gone out on you. with your mods, im surprised you don't have the cmdp (charge motion delete plates). you will need to turn them off with a tuner. there is a good write up on the net to make them yourself and save some cash, that's what I did, or you can buy them for about 300$. im sure you know about them. if not, there are butterfly flaps in the runners that open up at 3000 rpms for stock motors. they are very restrictive. good luck
