thanks for all the help guys. i didnt realize the difference in size of the tb's was that big lol. but i definately have a stock tb. and i think the idle problem is the iacv. because if i unplug the plugs on it the idle doesnt change at all. but if i pinch off one of the 2 hoses going to it the idle drops. so i think the aac motor is bad. anybody know where to get a cheap rb25 aac motor?
