Idle Air Control Valve compatibility
i have an LSV in my crx and my IACV is starting to go bad. i tried cleaning it and it didnt help. my question is this...
what IACV are compatible?
i am running an obd0 intake manifold on my 95 B16 head. i want to assume that one from an integra will fit. does anyone know what years are compatible?
DA 90-93?
EF 88-91 Si Version?
i know newer civics will not fit because the bolt pattern is different. thanks for any help.

Re: Idle Air Control Valve compatibility
ummmm. no.
i said im running an obd0 jdm intake manifold. obd1 iacv have bolt holes that are closer together.
anyway. i went to the junkyard and found an iacv from an HF and it bolted up. but there is a difference. on the inside where the openings of the IACV meets the manifold there is a metal screen on my b16 iacv but none on the HF iacv. i found some DA's out there but without the iacv, but those bolt holes appear to match up as well. here are pics of the HF IACV on my spare B16 mani. i did find a compete LS motor but the car had been covered in mud and moldy like it was pulled out of a river.

my rpm's keep surging starts out at 3K and then as the motor warms up it slowly lowers until it hits under 1K. when i had my old HB with a Z6 same symptoms were fixed with a new iacv

ok well sounds like a plan then. just thought i'd ask cause i had a slight surging idle on my car some time ago and it was remedied with a new iacv seal. your problem however is obviously much greater than what i had going on lol.

Re: Idle Air Control Valve compatibility
yea, the only question i have is will the metal screen from my obd0 b16 iacv make a difference if i install one from an obd0 d-series or 90-93 iacv from a ls?

Re: Idle Air Control Valve compatibility
ok, so i went to the junkyard and found some iacv's from 88-91 civic/crx that are mpfi and 1 from an 90 B18A1. i only see 1 difference between the 2 types. there are 2 ports on the civic/crx iacv they are both open and the on the B18A iacv one port is open and one port is somewhat filled in (see pics below). will i run into any problems by running the one from a D16A6 motor? the reason i ask is because one of them is near new. thanks

Re: Idle Air Control Valve compatibility
i guess the only way to find out for sure is to slap it on and try it out, i have never seen the small hole either.

Re: Idle Air Control Valve compatibility
i will start off by cleaning off the one from the B18 then install that one. if my problem continues then i will install the D-series one. thanks
