This is an excellent tutorial. I've cleaned mine before, but never really understood how it worked. I had also seen a *guess* on how to set it on another video. I followed that and screwed mine all the way in, then came out 1 turn. But like I said, that was kind of a guess. It makes much more sense that it would be screwed all the way in. I might put a super small dab of high temp thread locker on there. I actually made a tool for this out of a piece of steel that will go in both notches at the same time. Works great. Thanks for the excellent video. Finding someone to work on these cars who understands them, is getting really hard to do. Nice to have a helping hand on the interwebs!!!
Thanks for this video, I own an 87 honda civic si hatchback and it now idles correctly. That plastic retainer had worked its way 3 threads away from the top of the valve. I knew mine wasnt performing correctly and there arent any replacements readily available so I delt with the surge for quite some time. I really appreciate it!
I have the same car! Unfortunately my problem is not as simple. But I'm gonna try this again. I cleaned the throttle body & intake & we'll more power baby lol but still surging idle
But before you open the fast idle valve, after the car warmed up, you need to check if there is an air suction trough the fast idle valve whole bottom one with your finger or fingers on the throttle body after you remove the air hose, if there is air suction, so the fats idle valve is the problem, if there is not, the idle control valve is the problem, of course you need to check if there is a vacuum leak somewhere before you condemn the idle air controle valve: my 99 Honda crv was idling high at drive almost 990 to 1000 RPM, but the idle surge up and down at park or neutral, but the problem wasn't the fast idle valve , but it was the idle air controle valve, I replaced it and the problem fixed. This second time almost the same problem happen hight idle almost 970, but the idle surge up at park or neutral and stabilize back at high idle of course, I checked the air flow with my finger on the throttle body after the car warmed up and it was air suction trough the fast idle valve whole, the same suction power whether the car cold or warm, the fast idle valve is dead it doesn't move anymore, ( I knew that after adjusting that plastic cycle with flat screw driver but no change ) so I closed it and problem fixed till I buy new OEM one or buy the whole good used throttle body may be on eBay.
I have an 86 civic hatchback dx. When you start it, it idles high af to start. After a bit you can blip the accelerator and it drops down to a good normal steady idle. Pretty new to owning it. Is this normal? Or is there something I should look at to adjust. No lights or codes etc. Engine only has 65k original miles on it. Thank you in advance
That one is a little harder, I don't think that has much for computer control, it's carbureted which is a completely different beast. As far as I know it's fairly common for those to do that - kind of an auto choke to start the car then when you blip the throttle it goes to a more normal idle. I am not super familiar with much before the 88 Civics.
@NaytonTechGaming thank you. I appreciate you getting back to me. Once it's warm it runs and drives great. If it ain't broke, I won't fix it until it is 😁
I have a 98 Honda CRV my problem is it idles high at about 1400 but then it'll idle down to about 11:00 then I had a computer check on it and it's saying the O2 sensor is bad Bank 1 do I believe that or try the throttle adjustment thing you just did in this video
@@herbiedunlap5534 My next move is to change the fuel filter. If that doesn't work, I'll inspect the fuel pump. I'll change it if it's bad. After doing these, Remove the Radio(back-up) fuse for about 15 sec, minimum then put it back on. The fuse is on the Under - hood fuse box. Tomorrow and the next. Hope it works! I already did all the valves outside and inside, checked if there are any vac leaks, and even checked my throttle body sensors including the IAC and FIT valves. This is my last easy way out. I'd hate it to be a transmission issue.
hi i opened 2 days ago to clean the spring jump over the tree i couldnt find.t i hace idl high up and down even the car is hot is anyway to find spring for that i am looking for spring my car honda civic 94 manual temporary i block the whole with tape the car working fine were we find spring thank u
Prime example of how ALL TH-cam videos should be educational and to the point great video.
Thanks dude, I have had problems with the car's revs for 4 years. Thanks to this video I have managed to solve the problem that was driving me crazy

You are welcome!!!
Thanks man, i was lookkng for videos to how exactelly addjust that, but now o know thanks to you.
THE best explanation of an FITV I have heard yet.......
Thank you!!

One of the best vids I've seen

Thx for this video , I have a 87 prelude with crazy idle , hope this will fix it
Thank you sr well explained and to the point .
Nice vid.
Is ultrasonic cleaning this an option ?
thank you, really good content.
Thank you for your video.
Thanks for the explanation
Great video!
Thank you!
good vid mate, thanks.
Thank you!!
Are the mirror block off plates for the Ef hatchback gona be available soon...?
Yes, I'm going to work on them during the live stream this Sunday - come join in - going to have some giveaways as well.
Where does that hose above the sensor connect ?
Mine is disconnected and i have idle problems.
Same for a 1980 accord?

@@amanhasnoname6628 just changed the transmission!!!
@@herbiedunlap5534 Ugh, did it help?
If I run a long distance and I have to gear down to a stop the engine shut off
Me too! Did you find the issue??
How about if the idle going up and down all the time when cold or warm .. I got my civic 95 , and i already chnge iacv and map sensor but still same 😢
Did u ever get it working I'm in the same place
Adjust your iacv . My iacv problem . Fast idle
I got a 5th gen prelude and still have this problem. I will try this next
Is it possible to be tightened too far
Probably. I usually only cinch it since it's plastic, if I you twist on it too hard it will crack.
Could it cause it too idle lower than it should if closed too tight ??
@@teaspoon87 It shouldn't. If your idle is too low after this adjustment, you should use your idle screw to get it back in spec.
@@NaytonTechwere is this screw
