IACV clean / check !

**dvsx** · 06-07-2009 04:10 PM

i just did this on a b18c2. previously it was jumping between 1.5k and 2.5k until it warmed up which it settled on 1k.

now its idling better, at 1.5k but still a bit wonky and the engine check light is on.

do i need to reset the ecu?

the car came with a tuned vafc2

EDIT: engine check light was on cos i forgot to plug the electrical cable back in lol... but the idle goes bad again. would it be in need of a retune?

Adjust the idle control screw with screw driver. Im not sure where it is on the b16 but on the y4 its on the throttle body. Its a little flat head screw u adjust to increase or decrease the revs.

Thanks Gio - will give it a try - the funny thing is yesterday all was sweet idle @ 900-1000 - this morning didn't want to play idle stayed at 1500rpm after car was showing normal operating temp on gauge!! - is there any sensors for temp that enable cold and hot cycles???

I think mine sits around 1500 when warm, i do think its too high (should be about 1000) but i havnt got around to adjusting it.

I'd adjust the screw first (when warm) then if that does'nt work look further into it

when warm it shud be idling around 750-800 imo

my problem was the FITV not the IACV. fixed it up and no more jumping idle on cold start! idles at 1500 cold and 800-900 when warm

Yes yes,as above,the FITV.

Where's the honda-tech link to adjust the FITV?

Where is the FITV located on a B16a??? I found a link for fixing it on an accord

After you locate it...You adjust it by opening it up (2 screws),use a mirror to see in there,if needed and just turn it until it idles fine.You can fine adjust the idle with the idle/air screw.
