This video was very helpful. I have a 94 Honda Accord and the advice in this video was perfect for cleaning my Idle Air Control Valve. So far, it looks like my car is running much better. Thanks for posting this!
My accord has got some idle surge going on. I will be cleaning my control valve. Thanks for the great vid!
Did it work?
This fixed our problem with low idle ~ thank you for posting this!
Man, your video saved me 600 reais (about 175 dollars), my 1995 Honda Accord was dying when idle valve is requested (after 1 minute on for heating), so I cleaned the valve and my car came to life like a charm! Thank you!
Roberto Iglesias Awesome!! Glad it helped!
I'm rebuilding my son's 97 Accord engine and will be performing this task. It has almost has 250k miles on the clock and I'm almost positive this has never been cleaned. Thanks for the video!
Thanks man my f22b has been idling ruff for the pass couple days thanks for the video
Did it feel like it was about to stall at stop lights ?
Nicely done that fixed my problem, thanks for the video. I had to take it apart after i was done because i forgot to put the gasket back in. But i took it apart quickly. Thanks again.
Awesome!
My 97 Integra was idling at around 1600rpm and then dropping down to around 800. I pulled the idle control off and cleaned it. It was all gunked up. Fixed the problem. About a half hour of work. Thanks.
AWESOME! Yeah it's an issue with most early model Honda and Acura's.
Spoke clear,didn't make it complicated, great job 👏
Thanks bud hoping this fixes my idle issue for my 94 wagon
Thank you, it worked for me
great video thank you so much well explained
Yup worked great thanx buddy
Great video really appreciate it !!
Very informative thanks
Thank you for an excellent video. The IAC valve is exactly the same on the 1997 Honda Accord EX (F21B). I hope cleaning this valve works as the list price on a replacement is over $400.00. What a joke! I was amazed to find the same carbon buildup in the screen and a large amount of buildup in the open port. (I attempted to spray cleaner in the upper port in the throttle body housing and that did not work.) I filled the open port with throttle body cleaner four times, allowed twenty minutes for it to work and dumped it into a clean, clear, container. The cleaner was dark brown, almost black, on the first two cleaning attempts. It was a still brown on the third attempt and was not completely clear on the fourth cleaning. I will repeat the process until the cleaner is relatively clear. The engineers at Honda never had to work on their own vehicles. There is very little room to work and it is very difficult to remove the bolts. My Craftsman 12 mm ratchet combination wrench (old enough it was made in USA and not the Chinese junk they sell now) was a great help. The fuel filter is very difficult to replace as some moron decided to move it from the upper firewall (the location on most Honda cars) to a place slightly above the steering gearbox and below the master cylinder on the driver's side of the vehicle.
Thank you very much for the information. How can you determine the engine numbers you mentioned at the beginning or where are these numbers located?
Is there any component on the Idle Air Control Valve that wears out or does it just need cleaning?
Is there any method to confirm the signal from the IACV to the ECM without removing either one?
My idle was high, then hunting from low back to high. And now has started dieing while slowing down, this seems to be the fix, hope it works, thanks for the vid.
Did you ever fix the high idle problem
Did did that fix ur high idle problem
i did this and now i have coolest leaking from those two valves. Is there something i did wrong? is there a sealant i can put on?
btw the lines where the hose connect to are really oxidated
Good video
Every now and then when I start my 95 2.2 odyssey the engine will start but shut off as soon as I let the key off the start position. It might do this a few times in a row and then start and run normally. Could a dirty gunked up throttle body be causing this?
what's the best way to take the ex model f22b1 off...I found mine but its up against the fire wall
thank you. this video helped me and my Accord now is running smooth. god bless
michael laguille AWESOME!
after i clean the iacv. rpm is at 1500-2000.. what do i do sir
Awesome!
after I took off my lines, I forgot which one connected to which... there is a smaller line and a slightly larger line, but the ends to the sensor are the same... it seems like it should be one way, but I would like to check and make sure with you which one is for which, I'd hate to connect it backwards.... facing the vehicle's front, my larger lead looks like it comes from the left to the intake with the butterfly doors. my other lead comes from the right and looks like it goes deeper into the bottom of the whole thing.
Imma try it how long should I let my car set ? After driving it too insure peak safety
Thanks
i replaced my ACV on my 02 honda accord 2.3L and i guess i was in a hurry putting it back together and i might of mixed my two hoses in and out. I started it the iddle going up and down didn't change even after reseting ECU. I drove it home like 2 miles and i noticed coolant leaking and smoking a little bit. Immediately i realized i might of mixed my two hoses so i took it appart switched them back and the iddle fluctuating went away but now my car will sorta choke when i put it in gear to take off. I let it sit a full day hoping the coolant would dry or something but came home started it and it kept doing the same thing. I do have a cold air intake and a throttle body spacer idk if that makes any difference. ANY SUGGESTIONS OR IDEAS ANYBODY PLEASE!! I NEED MY CAR RUNNING FOR WORK. Thanks ahead of time
hey at 2:17 is that metal piece the ground and does it need to be attached mine was not as i took it off
I'm curious if this will fix my issue with when I turn my ac on my car it starts to idle rough
Then clean and install is installed and there is nothing else to do? I read that there is a need to calibrate the valve iac that is true or not? I wait for your answer my friend
My car is a 1997 Acura CL. It was idling rough up and down while warming up. Was running somewhat OK at a steady speed of 40-50. As soon as I slow down or speed up it started jerking and the rpm went ballistic. Slowing to a stop or at idle I had to play with the gas pedal to keep the engine running. Needless to say, this can be dangerous when driving and having to slow down or stop suddenly. Today was the day to clean the IAC and intake ports.
This video doesn't really show how difficult it can be to remove the hoses from the IAC. As a matter of fact it was impossible because the hoses are to short to pull the IAC up and disconnect the hoses. I left the hoses clamped to the IAC and left the whole thing dangling. Started spraying both ports using seafoam. Used a soft toothbrush to avoid damaging the tiny screen that covers one port and scrubbed gently around it. Worked like a charm.
Idle is back to normal.
nice 5 years in the future i will say most older cars are so gunked up and oxidate on the hoses. so i recommend leaving it dangling if you can. or at best buy new hoses before you do this and then you can replace the bad hose
of the two gold lines that connect at the bottom of the mass airflow sensor, is it normal to find water in one of those hoses? or is that the coolant leads that you were talking about?... when I removed mine, it seemed like one was empty, and the other seemed like water, it didn't have a scent.... how do I remove the water if this is the case that the car might've been flooded before my ownership?
please help me, thank you for your time, and this is a great and very helpful video
It was probably just coolant
Gracias
My TB was wayyyy dirtier than that!I got a big flat head and held the throttle plate open so I could scrub it down with a toothbrush, Don't break the toothbrush be careful! I used the cheap O'rielly's carb cleaner.
Does anyone know what the Ohms should be between the pins?
my honda accord is shaking a lot every time i stop can you pls help me out
will give this ago tomorrow i will post update
Unlike an Accord, the location of the IACV is almost inaccessible on a 1995 Odyssey.
The back of the hood which you see @1:15 is extends more towards the front in an Odyssey, which "buries" the IACV deeper in the engine compartment.
I cannot imagine how one would access the two bolts holding the IACV.
Seems like the only recourse is to disassemble the entire air intake boot and manifold.
Was there a mistake with distinguishing the 10mm bolts vs the 12mm?
Most likely lol They're 12s for sure and the hoses are a PITA. I'm gonna clean mine today bc up-down idle at warm up
would cleaning the idle air control valve on my 97 accord stop the engine from revving up and down?
Its not a guarantee but it might stop it. You may also want to look into the fast idle valve or look for vacuum leaks
iTz_DaNiiLo how do I fix the idle when you drive it for a while I'd say 30 mins and it'll want to idle high (1500rpm) then later drop back to 750 rpm
youngmanners hey man ..kinda late but did you ever find a fix?
Yes my 94 Accord was doing that but it was worn out so I had it replaced and now it runs great.
Flush coolant. Make sure radiator isn't rusted or cracked. Clean throttle body and components like on video. Clean IACV and Fiacv. Adjust Fiacv if necessary. REplace gasket on IACV with oem gasket (very cheap). Replace radiator with new Honda coolant, and bleed to get air out. System should work perfect for the life of the car.
This video is great... wonder if this is what is wrong. Can you tell.
First car started shaking so I checked the spark plugs and noticed that I needed to replace the valve gasket seal... replaced everything plugs including wire... did an oil change and replaced air filter also. Car still feels like its misfiring, and today I noticed smoke coming out of the chamber next to air filter behind battery..its a little peace that comes out... it was smoking and now my car will not stay on, idle drops and then shuts off at times it will not start. Could it be this? 94 honda accord
Sounds like a good start. Did you clean the oil out of the spark plug wires? Also what model is your accord? DX, EX, LX? The DX and LX models have another set of valve cover gaskets under the cam assembly that often leaks as well. If recheck and saw if the oil came back.
Thank you so much for replying.
I replaced the spark plug wires all together... cleaned the oil out where the spark plugs are at... thought that would do the fix and as I mentioned decided to do an oil change and change ail filter... car feels like it jumps when driving at least on 3rd speak mostly 4th. I have a 1994 honda accord dx
It will idle right at the one when I start the car and then it drops and the car shuts off. Even after the fix on my way home doing 50 the car shut off on highway... I have no check engine light or anything... trying to see what I can do at home to fix the issue instead of a repair shop.
It's doubtful this is your issue especially the cutting out at 50mph. However it sounds ignition related either in the ignition switch or the ignition system (coil or ignitor). Here are some links to help you diagnose further:

God luck!
Thank you so much... that information made a lot of sense, because my key switch is having problems, it is hard to start the car some times cause the key will not turn it gets stuck at times... the info you gave me made sense. I think I might have other problems also...because when driving it does a shake, like the feeling when a car (manual) is just about to stall it does a hard shake and then cuts off that is what it kinds of feel like which made me to believe it was misfiring...but after fixing it still does it... Ill def look into the switch... Thank you so much
I hate how he doesnt show how he took it off
great video, I'll be doing this this weekend. I have to also say, I CANNOT WAIT until we move away from saying the phrase "go ahead" before every...single...instructional step..
that said, I DO appreciate the video...
Will this work if my gas pedal keps getting stuck? I don't think I have an idle problem, but when I take my foot off of the gas pedal it gets stuck and continues to accelerate.
It could, sometimes cleaning the throttle body will help a stuck pedal. If it doesn't help you may need a new cable
The bottom bolt below the black thing is stripped and I don’t know what to do to get it out…
Hi in what situation do I need to replace the IACV? I have this question because my car is fluating idle and I was thinking if I just cleaning I could solve this problem. Thank you for your attention. Bye.
Jorge Caldas while there are a few reasons why it's doing that is try cleaning first. Also make sure you don't have any air pockets in the cooling system. Also if you have a code for IACV you may have a wiring issue as well
Thank you for reply me and my problem is very confuse because it happen only when the engine is hot and I put the gear in neutral but if I at that moment I put the shift on any gear it stop.
Jorge Caldas I had the same problem issue on a 92 civic that would idle irregularly only when hot and it ended up being the throttle position sensor.
I've been working on Honda's my whole life. I do Not recommend ever adjusting the base Idle on any Honda unless it's an older Carbureted fuel system. it's set at the factory aided by a computer Scan tool. that is why they cover the Screw with heat tubing shrink because they don't want you to touch it. thanks.
treluvsjay1 totally agree however there are some cases, like throttle body replacements, which occasionally warrant this

BTW, just spraying into the throttle body while holding high revs? No. Just no - unless you actually *WANT* pop an exhaust valve or two. Thought I'd play the odds. Hard and expensive lesson learned
Hi, I've been having some trouble with my 1994 Accord f22A, it's been losing power, not accelerating when I hit the gas and eventually shutting down as I pull over.
It gives also won't stay on for long if stopped (at a stop light for example). just yesterday a mechanic did a bunch of tests, drove it, left it on for a while and said he couldn't find anything wrong, but when I got home and tested it out, it started doing the same thing again.
what could this be?
thanks in advance
It could be the throttle body is dirty or your throttle cable is sticking
Can this fix high iddle prblems mine goes up when is cold then goes back to normal
It’s definitely possible
@@hondapartshero ill have to try it then
Dont forget to bleed the coolant system after youre done
How?
aren't you suppose to use mass air flow sensor cleaner to clean the iac valve?
I have Honda Accord 1994, When I'm having a long drive and my speed reached 110 KPH, the RPM dropped to Zero (Engine stop) when I shifted to neutral gear, What shall I do or how to fix this problem? Pls reply..
Check timing belt, and that valve. Mine did the same thing and my timing belt was snapped. It would turn over just not turn on.
My 94 Accord had a broken timing belt. Water pump went out so it was leaking water. Idle control valve was no good and my radiator was no good. I replaced all that and my car runs great but mine was different situation. My car shut off on me and that was because the timing belt broke. I would check the timing belt.
You don't show how to remove the two 12mm bolts. Their is no room to fit a 12mm ratchet back there. Did you use a short ratchet or something? Can you maybe post a pic of what size ratchet you used to fit in that tight space? Thanks.
I used a gear wrench brand pass through socket wrench but you can use a normal box end wrench or a ratcheting wrench as well.
I bought a small stubby 12mm ratchet, but I can't seem to get the two bolts off. They are on their really tight. How did you get them off? By hand or did you use power tools? Is their a specific order when taking these bolts off? Thanks
Ron Yassa
I did this today, to my '96 Honda Accord. I used my hands with a 12mm socket and wrench. I worked on the left side of the car, driver side. @2:07 of the video, remove the bolt that houses the wirings. It will give you more room to access the bolts on the IACV.
How much carb. Do we put?
I'd use just enough to get the dirt out. Like maybe 1/4-1/2 small can
Thanks
You may have air in the cooling system, search on here for bleeding the cooling system and see if that clears it up.
Thanks. I will let you know.
I can't ajust ac or heater speed
where is the idle adjust screw on a 94 Honda Accord?

@@hondapartshero Hello sir, can you send it again ? Can't open the image , thanks.
It's 12mm
Carburetor cleaner is not the same as throttle body cleaner.
so do i use throttle body cleaner on the IACV? or Mass Airflow Sensor Cleaner???
The difference between throttle cleaner And carpet cleaner is that you can't use carb cleaner if your throttle butterfly has a rubber seal on the bottom. Carb cleaner can affect that seal. I don't believe most Accords or Civics have that seal but you need to look before you spray it with carb cleaner. The safe thing to do is to use throttle body cleaner when you're working around the throttle butterfly.
