IACV issue
 

Yes i ------- searched ::)

Anyway, 00 civic, running crome on a p28 with a conversion harness. It seems whenever i run the p28, my idle gets all fucked up, which i'm assuming is caused by the p28 not controlling the IACV or something. Because when i took my turbo off for emissions and ran the stock P2P, it works fine. Am i just missing an adjustment in crome possibly? WTF is up here?

Re: IACV issue

Re: IACV issue
 

oh god, 1 question, 2 different answers...


yeah i have a 00 civic with the original y8, so that's 2 wire IAC isn't it? (maybe it is 3, i don't remember)

what does the evap purge have to do with anything? How do i unplug it? I assume it won't set a cel because OBD1 doesn't support it?

also if i do need to swap the bitch, i guess i gotta find an OBD1 ?

Purge solenoid control goes and gets itself fucked with most of the DIY code out there. Lose the purge solenoid, and lose a lot of idle problems.

Look under your hood and tell us which IACV you have, hmm?

Re: IACV issue
 

I'm almost positive that obd-2's have a 3 wire, and obd1 and obd0 have 2 wire.

Re: IACV issue
 

obd2 vtec 5 speed=2 wire
obd2 vtec automatic=3 wire
obd2 d16y5 hx=3 wire (98%sure)
obd2 non vtec=3 wire
obd1all=2 wire.

Re: IACV issue
 

yep that sounds right, so i have 2 wire (i'd check but there's a monsoon outside)

how do i disconnect the purge solenoid, and where the hell is it?

Re: IACV issue
 

on the y8 it should be mounted to the fuel rail under the black plastic cover on the fuel rail. put the p28 in and unplug the solenoid. it didnt show a check engine light for me. im running a po6 on crome so i dont think you will have a problem.
