I just bought a crx with a b18a1 swap in it. Idled fine when i bought it, right around 700rpm. Did not touch or mess with anything on the swap and now it will idle close to 3 grand when cold, then purge from 1200 to 2500 rpm's. I've checked out most of the vacuum lines an they appear ok. i've heard some things about the FITV. i found it and took it off but appears to be ok i guess. it has coolant running through it. i pinched the pcv valve line while it was running because i heard that narrows it down but it did not do anything. if it is the FITV, where can i get one? i looked it up at advance auto and nothing came up.
