hey bro heres a pointer I did a while back. ok, the ficd and aac are just a simple solenoid. most nissans in the 90, share the same solenoid just in a different housing, I got my ficd from a quest( take the harness too) and my aac from a maxima, just hit a junk yard and look around. 300 bucks is a lot. or check ebay, ive seen the whole configuration go for as cheap as 40 bucks. now there are people who believe that u should only buy new and that's great if u got it like that and if u do more power to ya but if not get resourceful. good luck
