Re: Idle air control valve
My Idle control valve didnt have any coolant lines hooked to it. I had coolant lines running through my throttle body though. Originally I just used a connector and looped those, it was good for a bit of power even. Hot TB isnt the greatest ting :( Now those lines feed the coolant on my turbo ;-)

Re: Idle air control valve
another thing that can happen when you have a bad IAC valve is the car makes a "humming" sound out of the intake...thats what mine did, slaped a new IAC on it and it idles perfect now
|
Re: Idle air control valve
to check for vac leaks spray acetelyne around all the posible leak points.
if the rpm goes up u found the leak. |
Re: Idle air control valve
my buddy had the same problem, take off you intake and look in the throttle body there should be two holes in there. one of them leads to the IAC sensor plug that it'll stop the problem. well at least it did for us.

Re: Idle air control valve
I've been having high idle from 1500-2000 no vac leaks. the car stalls when I closed the Iacv hole the TB. I've tested 4 IACV. none fixed the probem. same IACV works on other people's cars. I've had this problem on 3 different engine and 3 different intake setup. I got tired of it and bought a edelbrock intake and TB still same problem, I changed ecus and Chips still same problem. I am sick of it. so now I just ignore it.
I was thinking about blockoff plate thing, but I would drill really small pin holes in the plate to get the car to idle. I plan on doing it this week |
Re: Idle air control valve
Ive been having a similar problem. Car starts Idles at like 800. then falls to 3 the goes back to 8 for s while..It is rich as hell. my scanner is reading the front o2 sensor. and heater circuit..but he voltage isnt changing. so its rich like the sensor isnt working. changed sensor no luck. walked through a wirining diagram checked all the connection from the primary o2 sen. and followed them to the computer did a continuity check all work fine..just no voltage changed then i put in a gsr computer same thing.

Re: Idle air control valve
ive had this problem for like almost 2 years now. i just ignore it now and laugh when peeps think i wanna race them at every stoplight..... you would think theyd notice a looping idle, but o well.
Ive tried everything less than taking it to a shop and saying find the problems for me lol. |
Re: Idle air control valve
what about idel that goes up and down UNTIL its warm then its fine? pop can trick works for now...
EDIT pop can block off worked great till my car was at normal temp then it just shut off.. |
Re: Idle air control valve
I had the same idle problem on my zc so I replaced all the vacuum lines, which had never been replaced anyways, cleaned the evac and the problem went away.
|
Re: Idle air control valve
Well mine sat at a shop for 3 weeks, and that guy drove hiself crazy trying to figure it out. needless to say the idle is still fucked.
so far ive done. all vacumme lines checked brand new iacv from honda (didnt work took that bitch back lol) tb gasket the guy told me he thought it was my intake, which didnt sound right at all, but ---- it imma give it a shot if I can ever find a cheap stock intake. and as soon as i find a uberdata tuner locally that bitch is getting done for good. |

Re: Idle air control valve
i had this problem with my obd1 converted 96 civic. never figured it out. seriously checked everything even replaced my iacv. i think its jsut a side effect of converting obd's
|
Re: Idle air control valve
mine was the FITV. its on the bottom of the throttle bod. takes less than 10 minutes to fix... just take off the plate and screw the white round thing all the way in. should look like a small button in the middle. and the white ring has 2 little indents on it, perfect for use of screwdriver lol.

Re: Idle air control valve
dunno whats the problem with my eg3 dx 1.3 single carb
when u crank the motor it revs to 4.5k rpm and sits there for a couple of minutes then it goes back down to 1.5k rpm or u move off and speed up to 20mph+ revs drop back to normal when u press down the clutch the revs drop below 1k rpm and stalls when u stop some one plz help me :( |
Re: Idle air control valve
my intake hums really loud.. that means my iacv is bad? cause it idles fine as long as im using a obd2 ecu..
|
Re: Idle air control valve
What intake manifold is on the car?

http://www.hondaautomotiveparts.com/...13SR80_D04.gif This diagram sucks, but see #13? under the TB? That whole the large dingus is the FIV. Fast Idle Valve. It has a thermo-wax plug that when cold.. opens and allows more air into the intake tract to warm the car up quicker/help cold idle. As coolant temp rises the wax expands and closes it. What happens is over time the wax plug gets messed up and it sticks open or closed.. usually open unfortunatly and it plays hell with the idle... especially warm idle since the ECU is then in closed loop operation. Some FIV's are on the bottom/side of the TB.. some are on the intake manifold itself. It just depends on the year/make of the Honda. As you can see above I keep 2-3 of these on hand at all times... kinda like igniters and OBD0 distribs :P I'm thinking about permenatly closing mine... what the bad about that? |
Re: Idle air control valve
FIV was my problem, I'm glad I got it fixed!
|
Re: Idle air control valve
i have a 97 h22. same thing on my car. revs up and down until warmup.
sucks! i cheated and fixed it using programible AEM ecu |

Re: Idle air control valve
ok so here is what mine is doing. i start my car up then let it sit for awhile hit the brake then it will start reving up and down. sometimes once the fan kicks on it stop reving up and down also. i leave my tubo timer on and walk away it straights out after 20 sec of running. i have clean out the icav ------ card clean around trying to find a vac leak and nuttin any ideas??iwhen im at a light and it starts doing that i can hold the brake and let the clucth out a litt and sumetimes get it to stop reving up and down. could i be having volt probblems?? i am blowing alternator solenoid valve fuses when i drive the ---- out of the car. have a b16a in a ef p28 chipped
thanx |
Re: Idle air control valve
This thread is dead.
But is it like the idle is loping or the car is threatening to stall? Start a new "help me" thread. |
Re: Idle air control valve
+1 i had that same butterfly problem when i had my old skunk2 TB (you know back when skunk2 had the problem that the butter flys would not close on their TB's some stupid factory defect >:() that made my car idle like complete ----

Re: Idle air control valve
i know this thread is very old but did anyone check the map sensor because it sounded like your guy's problem. have you guys tried disconnecting the map sensor for awhile to see if it goes back to normal idle?

Read how to make your first post. MAP sensor isn't going to lope your idle, it's going to make the car run like ass at part throttle, or barely idle at all. |
Re: Idle air control valve
well sry ---- it fixed my car so i guess i have a different problem
my integra was idling 750-1500 and it continued after i cleaned the FITV and IACV so i changed my map sensor and it was gone so sry if its not the same problem but i guess you love flaming new comers so ill leave u alone :-\ |

Re: Idle air control valve
My car idle bounces from 1500 to 2000 over and over again. it doesn't change when i unplug the connector, i don't think i have a vacuum leak (maybe i will check the IM or the PCV valve) i adjusted the idle speed but even after all that i can't get the idle down anymore than 1400. Can i accurately set my timing with this idle fluctuation?
This problem has been bothering me, especially due to the loud exhaust i have on the car, cuz the idle is loud as ---- too and at every speed. |
Re: Idle air control valve
My idle was at about 1700- 2500 and sometimes would stay steady, and sometimes would jump around, I had extremely LOW coolant, filled the radiator, and my idle fell to 1000 and stayd there. :1

Re: Idle air control valve
my ---- is running like that too eversince i got it boosted but im guessing its cause my ---- is still not tuned.
when ever i floor it and come to a stop it will idle all stupid but once i turn it off and turn it on it wont so im pretty sure i dont have a vac leak |
