no power at idle???

[NikFu S.]

i was reading the "you might be a ricer if" thing and i remembered that sometimes when im sitting at a light i can let off the gas and i wont move. no brake or anything it just sits there. sometimes i find myself on a hill and ill roll back when i let off the brake before i gas it.
its a nice effect and gives me very quick green light response but i cant help but think something is very wrong and broken.
perhaps the tranny is beginning to go south for the winter?

on that note im also wondering if fuel consumption increases due to the extended use of the awd and manual mode in low traction conditions.
