88-91 CRX DX idle surge fixed!!!!!

[@alannorkham8664]

8 years later and its still an effective video, thanks for the post!

[@Nick-vp1dk]

same my b2 is still kicking

[@GarageBuiltHondas]

Great video! Very well done! Keep those EF's running strong!

[@stanhelmle5363]

Wow! EXCELLENT video! My 1990 Honda Civic 'D15B2' can be driven again! I had already spent $750 with a shop attempting to resolve the issue (IACV, etc.). A half turn of a nut was all it took! Thank you so much!

[@smokingwithkeenan743]

Bro you just save my life dude I've been trying to fix that surge for literally years I don't know how I just found this video

[@cameronchisholm1748]

Thanks to your unselfish act of posting this video, I, an many others can extend the lives our 88-91 honda crx/civics. I had this problem for ~1.5 years, 20,000 miles before I found the solution. Never would have thought a nut would be the issue.

[@jarvisxiii]

Holy shit dude I had tried everything! I was just about to look into getting a new ECU until I found this video. I didn't even remove the dash-pot. I just popped the nut on the throttle plate loose, turned it maybe 180 degrees. Boom. solved. I wish I found this before replacing the IACV, MAP sensor, O2 sensor, and spending 5 or 6 weekends on this. Thanks a ton!

[@pableezy1988]

Man I already have done all of those gonna try this tomorrow crossing my fingers

[@paresident7811]

Thank you so much. Have a 90 DX sedan 1.5 D15B2 , 105,000. Just replaced the head and all the gaskets. Its been out of service for about 6-7 months. Started just fine. Let it warm up so I could set the timing. It starts to do exactly this. Talked to my son and he say "it does that sometimes." What?!? An he never mentioned it. Started Googling and found your video. Sounded too simple, but you did a great demonstration of the problem. I first tried a drop of oil where the pivot contact points are. That got rid of the hunting, but the idle remained over 1100. Turned the bolt 1/4 turn. Idle dropped to 800-840! Let it run for awhile. Idle remained steady. Went up when the fans came on and dropped back to 800-840 again afterwards. So awesome! Was then able to adjust the timing. Car sounds great! Thank you again and appreciated you giving a shout out to Eric the Car Guy. I've learned a lot from him too.

[@CKT1138]

You are a blessed human being. This heavenly 11mm bolt not only corrected the majority of my idle surge, it made my civic quieter, smoother shifting (I have an auto LX sedan), and less shaky. And I didn't even loosen it as much as you did, just one rotation with the socket!

[@only1platinum]

I am dealing with this same thing. So far I have spent frick'n $375 replacing crap on my engine. after I get off work I am gonna go loosen the bolt on my and if this fixes my problem I owe you big time. Thank you for this video!

[@MrBIGGERBOSS]

Dude....I can't believe it. I legit popped my hood and come to find out my nut was SUPER loose on my throttle. Just tightening it up completely fixed my idle after I replaced my IAC, did plugs and wires, even messed with the idle screw. And the whole time it was exactly what you just did. Thank you so much. Didn't even think to tighten that down. ✌🏽 thanks! From the guy that was about to throw a wrench through the windshield lmao

[@JamesJonahJameson-MM]

UdaMan. Glad there are people that take the time to explain things in detail. Very well done.

[@TheJaime145]

Thank you so much I checked everything on my 88 crx d15b2 ... It was surging between 1200 all the way up to 2100 rpms ... Rapidly!!! And I couldn't figure out the problem at all!! I did what you did and just loosen that bolt... And boom the idle dropped and settled... No more surging and it was idling smoothly also settled at 800 rpms... Very excited and thank you so much for this video.. I would have never figured it out and would prob replace a lot of things.. You saved me money..time...and hassle... Thank you again man

[@dongalvan8315]

Yo D!!! I have had this surging issue ever since we replaced my engine about 9 years ago. It wasn't bad at first ,very intermittent with the weather, but lately it had gotten so bad I couldn't even get the smog guy to look at it. I had replaced the IACV with a used one. That didn't work. fixed all the vacuum leaks, that didn't work. Then I finally did a search and found this video. Problem solved so far. I even tested it by tightening the nut back a little, and the dang thing started idling funky again! Thank for doing the research! You saved me a ton of money and time.!

[@SamTimelapseMan]

Bro i just fixed my 88 civic dx by doing this! Loosened it maybe 25°. This saved me hundreds of dollars and time, i know it means very little but i cant thank you enough.

[@ajmalanio4849]

It worked! Have replaced the tps and checked all vacuum lines and couldnt find the issue. Two turns and it idles under 1k. Thanks bro!!

[@williammedlock798]

I'm the first and only owner of a 1990 Honda.Civic. This helped! Thank you!

[@TheCarnager]

I can't believe it. All I had to do was loosen a nut. Man, thank you so much!

[@dickopotimus676]

Just bought mine last week and started doing this. Pulled that one hose and capped it and loosened the bolt, instant fix! thank you so much!!!!!

[@eliottconnor3227]

Good video. It fixed my high idle issue instantly. But then I was having a very low idle issue. I noticed the idle position screw wasnt making contact with the throttle plate at all. I let my car run and dialed in the screw to a perfect idle. FIXED! Thanks man!

[@tenkuu-yt]

Dude made one yt video just for this! I haven't even tried it yet and i already know its gonna work! Thank you bro!

[@willemsmeets]

I own a 1994 Honda Civic DXi 1.5 D15B2 European model , You solved my problem with the idle trauma that lasted for about 15 years, thank you so much!

[@stevengormely3543]

I have a 91 Civic DX hatch I've been working on. so much work put in, but that idle haha! I just tried loosening the throttle body nut like you did in this vid before I did anything else. Voila! no more fluctuating idle. Thanks for this video man.

[@chrislyles2443]

Dude! Bra! I can’t believe this idle surge issue was fixed with your simple suggestion. Thanks so much!!!! Unbelievable. Appreciate you making the video

[@hvacjohnnie]

Dude!! This was the first Word that came to my mind!! I can’t believe it worked for me too!!!

[@tomtrader1966]

mateeee your dad is the mannn my 1996 audi a6 2.6 was surging, and revs were at 2000rpm , i was cleaning the throttle body and tighten the shaft nut that runs thru the throttle body thinking it was loose, i did what you said and Banngggggg idle back to normal no more surging thanks to your dad and the video mate....and would also like to note that a few days earlier both my exaust manifold were glowing orange thinking my catalytic converters werent working....i was stumped until this video , no more orange exaust manifold ....awesum awesum awsum

[@billcampos3300]

This fixed the ghost idol on my car when cold in the morning on the Honda Civic 89! I drove it like that for 10 years! I can’t believe this fix the problem!!!

[@Plantdudejames]

This....has saved..my life... Now my hatch back can stay stock motor for as long as possible!

[@LoganDudley-i3f]

I’m in disbelief that it was this easy thank you so much

[@MariaGonzalez-ei1pv]

Great job ,this lil Hondas could drive you crazie figuring out...Great video...glad you made this video...

[@ZombiesAndOnlineGame]

All i can say is thank you....my idle was going from 1000-1500 and then drops to 700 and repeats. Cleaned and changed my iacv and loosend the bolt. Im proud to say it idles at 1000 then goes to 900 and stays lol Thanks you my man, single jingle life!

[@jicmagic]

Excellent video guy! Just did this on my 88 hatch. I had been having this problem for awhile and your tip was easy and it worked. Thanks for sharing.

[@NDNMochie]

Damn here we are with a 30 some year old Japanese Hot Rod and still find great videos on how to keep them going This one is a great reference video Thank You 🤙

[@johnashpaugh2182]

Life saving! I didnt even have to remove the part or the vacuum line, i just backed off the nut while the car was running until it stopped

[@B._Smith]

I gotta try this when i get home. Thanks OMG it worked! I wish i found this video years ago! Subscribed!

[@TheMidnightGarage]

great video! I just wanted to add, sometimes it can also be your throttle cable being too tight, loosen it up a little bit and you should see a difference!

[@bobroediger6121]

Great video and great idea on loosening the accelerator nut.

[@bboysunz]

Thanks for taking the time to make this video. I got a 93 civic with same problem and couldn't fix it. Has the D15B7 so I don't have that piece but I did do the opposite and tightened my bolt cause it was a little loose and BAM, my car idles correctly now. That was the only thing I didn't check cause it was never mentioned in the 30 vids I tried. Thanks so much!!

[@myluxor003]

Wow couldn't believe removing the dash pod would work but it did ....let's hear for Internet and the video you made bro. Saved me time and money and all I did was Google surging idle and there was the video. Thanks man!

[@isidrorubicamacho2257]

My dudes I just did this on my 93 Acura integra and that shit worked! It fixed the idle problem. Thanks!

[@FishSquirrel]

You for reals? You mean on b series as well?

[@th3k0ol4idman8]

THANK YOU! II replaced the valve cover gaskets on my 91 civic DX, fixed the firing order of my distributor cap and then it started that idle crap, did what u said on the video and all is good as far as I can tell, again thank you, like you said there is always going to be a person that has had that same problem

[@Greybuiltracing]

Dope!! Haven't tried it but I've done everything else . As soon as I get home from work I'm going to try that. Oh and shout out to Erick the car guy!

[@d-serieshuck2317]

Cool Allen let me know if it works for u man. Haven't had any more issues since this video was made.

[@johndoe65551]

Had this issue with my EF sedan after I replaced the head gasket. Good video man, appreciate it! That would have been my last guess and it was no where in my head lol

[@smilex100pre]

This solved my surging problem as well. Turn your BAT earning account we people can contribute to your channel. Godspeed!

[@jeremiahcook9013]

Hey bro your fix fixed my problem. I wanna say keep it up bro. Took me for ever. Then watching your video solved it so i made this channel to say thanks.

[@jaybrady3128]

After loosing my distributor on my 91 dx hatch and missing timing, i changed my timing belt, water pump, adjusted valves warrantied my wires, new plugs etc. got it all running and first start up my engine raced. Scared the fuck out of me. Messed with the throttle cable and t seemed to help but surged when I loosened it enough. Tightened it and ran to high. So I thought what you did and maybe adjust it. Wanted to look seeing someone somewhere has had this issue before. Just wanted to double check. Looked at Eric the car guy. Have that same engine and intake etc from my old 93 but 91 is still dual point. Thankyou for being the person I found first to confirm what I was thinking

[@perplexedpolygon6410]

88 civic wagon. Fixed "Update, it kinda does the same thing, but less agrees I've still revs above 1k. What i do now is when I turn it on i just pull the gas pedal towards me, and then it fix"

[@thetwentyeight5162]

The problem on my 88 civic D16A6 was the Coolant Temperature Sensor. It communicates with the IACV and it controls how much fuel is delivered to the engine. When it goes bad, itl tell then engine to add more fuel, so you get random surges like in this video. The Coolant Temp Sensor sits right under the distributor, so its easy to replace and only about $20. So its worth a try!

[@whozatmac]

You just fixed my car.

[@jeremyjohansson5558]

Great vid man still helping 10 years later! How’s to car still alive?

[@johndodson4527]

Beauty.thank you for the knowledge!

[@miclomusic805]

I experienced mine for the first time the other night after a touge run ! I remembered I seen this video a while ago I’m gonna try it out and see if it ever happens again ! 💯

[@southshoregraphics]

This fixed mine immediately, thank you. It also immediately gave me a check engine light for #7 tps. I had a wildly surging idle and no 4th gear before so it's an improvement.

[@southshoregraphics]

@johnny Macon Thanks good advice. Have to track down where the 4th gear pressure sensors are. I blasted the solenoids with brake fluid but they didn't seem to need it. Been adding more Lucas and seems to get better every couple ounces i add. Hesitate to put too much. I have an external cooler i'm planning to add too.

[@southshoregraphics]

While this fixed my idle surge temporarily, the underlining problem was a leak in the brake booster. Hard to detect that leak... New brake booster, perfect idle.

[@aimbotsnowman894]

Even 10 years later and it is still useful. batta bing batta boom

[@CUBAMUSICA84]

THANK YOU HUCK :) after messing with everything and months of searching on google finally my 1989 honda civic lx is running like its supposed to thanks to this video. I got oil in the spark plug wells and was overheating without losing much coolant. I still need to drive it for a couple days to see if this fix helps my overheating. I mention the oil in my spark plug wells because like me someone else might be thinking that this would cause a misfire and therefore give idle problems. BUT TRY THE FIX HUCK GIVES BEFORE BUYING OR PLANNING ON BUYING MORE STUFF. THANKS AGAIN HUCK AND HAPPY NEW YEAR. :)

[@johnnipps6417]

Cool video i will be back to talk about my results. Im having the same exact issues on my 90 si.

[@Followthelemming]

91 D15b1 here! Nice work man!

[@koshiii15]

Shoooooot, Trying this tomorrow man. Let you and yal know how it goes. 1991 Dx B2 Auto w/ Cruise control. Mine acts up right after the thermo opens up and before it's completely warm and started not to long ago say 180,000 and i just turned over 200,000. Wish me luckkk........

[@averyrucker3255]

good looking out man, never would have looked at this. fixed my idle issue easily.

[@prthunderr]

Wow! I was having the same issues with my 91 civic wagon. Thanks bro! I'm gonna try it tomorrow. Hopefully it'll work! 🙂

[@JC-pu1ej]

duuuuuude I just used this little trick to fix an old mans 98 LX that was surging... I thank you and he thinks you fr fr

[@russellhancock9765]

I just bought a 1994 Civic DX. I think it needs this done to it. It doesn't have a tach on it, so I am not sure how fast it is running, but I think this is the problem. Honda's are new to Me, so I am learning.

[@tattoosbychrisg]

You just saved my life INSTANT FIX

[@SimplyJ3sse]

OMG THANK YOU THANK YOU THANK YOU! This trick is awesome!

[@rex669]

Thank you so much I'm having the same problem with my civic and I just fixed thank you

[@marcoshoffner1738]

Shawn thanks for the info so far don't have that issue have 89 civic 327000

[@andycuriel]

my 1989 Honda prelude Si 2.0 has that same idle issue, when cold and turned on when it gets to 1500 rpm, makes 40 something "rpm drops".. and then levels out.. I will try this today and see for any changes! *any more great possible ideas?*

[@carlosarellano4]

Theres a lil Circle with a Copper cover with 2 screws on your intake manifold Anndy Curiel...only have to take 1 screw off slide the copper cover over, you will see a plastic thing with metal spring. Notice on the plastic circle it has 2 slits...Turn it with flat head and tighted it fixed my prelude!

[@carlosarellano4]

Read my comment below, hope it helps!

[@carlosarellano4]

Read my comment hope it helps

[@andycuriel]

carlos arellano thank you for your reply! I actually tried that 2 weeks ago and I noticed it diminished the RpM Drops by just a little. But I found that my problem was my IACV. I removed it myself and cleaned it inside and out and replaced the 8 shape gasket. Used a 90-96’ civic gasket btw. . Installed it when it was fully dry and BOOM! fixed my problem. Your advice is extremely helpful though to anyone reading this. Thanks Carlos.

[@AroMafy]

YOU ARE THE MAN! Thank you so much 🙌🏽

[@chelseam5927]

Thank you brotha! You gave me peace of mind!

[@16birdsonapowerline75]

I'll see if this solves mine. I'm original owner 89. This problem has stayed the same for over 10 years.

[@kensauve8401]

thank you for the good good news have a great day ken from canada

[@tonyp2707]

Question I have had this problem I have done everything. Iac valve. Bleed coolant system. Check vacuum lines. Your fix makes it go away but it came back. Do I just keep turning it. Also what does it even do

[@michaelkowalski2931]

Use some blue lock tight to keep it from tighten back up

[@WavyVaporizers]

I wonder if this is what's wrong with mine or I need a new throttle body. I replaced iacv etc etc and still has idle issue. I have a 99 civic

[@Mista808]

my 90 EF hatchback with the stock D series motor doesn't do this, but I'm having that issue where in first and second gear the car bogs quite a bit when I'm going through the gears.. if it's over 3k, the issue is not present.. any ideas if maybe this could be the fix? if not, any other ideas? so far I've replaced the plugs, wires, dizzy cap, rotor..

[@OhAustii]

Omg it worked for my 1988 honda civic lx thx so much man

[@handymanny90srozotto51]

Thank you buddy, much appreciated knowledge.

[@journeyquest1]

What about the raggedy ass seats? I have the 90 DX DPFI

[@JodBronson]

Hey sr thanks for this video do you think is same proces for 2.2 h22 honda prelude automatic 1999? Having this problem..

[@jackjonson2696]

Thanks very much for your reply mate. Ill have a look at that video. Thanks

[@runescapefan0001]

This worked on my car and I don't even know why. I just loosend the nut on the throttle and the bouncing idle went away. Why though?

[@lindamurray6537]

I would like to know why first before trying it..

[@bobbyhill302]

Keep up the good work brotha👍🏾👍🏾
