How to fix a honda idle issue (6 common issues it could be)

[@NGH99999]

I just had this idle surge after replacing a bunch of original parts (breather chamber, PCV, IAC valve, intake and TB gaskets, coolant transfer tube o-rings, injector seals, knock sensor, etc.) on my 98 Civic's Y5 engine (CVT). Here's a few things I learned. Maybe it'll help someone else with their situation. Used the Lisle spill-free funnel kit to make sure I bled all air out of my coolant system. In doing the above work, I had to do a complete drain of the system (including pulling the block drain plug), so the entire cooling system (block, head, all heater plumbing, etc.) was essentially full of air when the time came to refill with coolant. Once I refilled the system, it took over an hour of idling and multiple fan cycles for the system to completely burp all the air pockets. During this process, occasionally rocking the car up and down helped dislodge bubbles, as well. I also serviced the throttle body for the first time in 22 years. The engine side of the throttle plate, and all internal passages, were filthy. I cleaned the throttle blade and bore w/red Scotchbrite and solvent until new again, taking care to remove only the crud, and no aluminum with it. So at this point, minus the crud buildup, the TB is back to bypassing proper airflow around the throttle plate. This bump in airflow also confused the computer at initial startup. Idle bypass air screw adjustment: was originally sitting at about 1 full turn out from seated. After TB cleaning, 1/4 turn out from seated was all that was needed to put bypass airflow back to where the computer wanted it. IOW, after cleaning the throttle body, the engine didn't require as much additional bypass air from this part of the system. Beyond the above, I pulled both leads off the battery, clamped them together for an hour, then reconnected them to battery. I read this somewhere online - one of the many different "procedures" people use in an attempt to reset the computer. Then turn ignition key to run position for a couple seconds. Then I started the car and left it alone for a full hour to relearn idle. Was interesting to watch the tach, and how the computer kept adjusting RPM to sort itself out. After that hour, the idle still surged very slightly, but after a couple of additional drive cycles, it's idling rock steady and the car runs like the day I drove it off the dealer's lot.

I like the way you teach / explain things. Very clear and direct and easy to understand.. .Thanks!

[@chickydogbreath1]

Gonna do this tomorrow it's very likely a coolant level issue. I'm getting the 900-1600 rpm revs. While testing looking it over earlier I noticed the coolant was below the min. Also when I turn on the AC the idle revs up to 2000 and stays there but doesn't surge.

I have been lazy and not checked my coolant level in a long time. That was exactly the problem so thank you for pointing this out as the most common problem.

[@RonaldrubynDominguez]

I want to thank you very much for a very thorough explanation of idle issues on Hondas. I I happen to have a 98 Civic EX that's been giving me problems. I just rebuilt the transmission, and replaced the engine solenoid Andy Transmission solenoid. But the engine still tumbles a little bit and so I'm not completely happy. I replace the motor mounts as well. Still I'm hoping to get better gas mileage out of it. I was averaging 14-15 miles per gallons. It used to average 24 miles per gallon (32 hwy).

[@markstroud4956]

Its gonna be great when you get a beater and rebuilt the whole thing. Going through each system and how to work on it. Then top it off with one of your paint jobs. Have a great year.

[@TexasHondaChannel]

[@rolandomacielmagana7469]

Omg you are a genius, a genius!!! My idle was doing that bouncy stuff and when i was shifting it was pulling me and choking the engine and i have replaced all the sensors on the throttle body and the iacv but bothing, and then i decided to try out to spray carbon cleaner on the manifold gasket and there was a leak, i was seeing bubbles so i am going to replace it and see if that fixes my issue, hope for the best 🤞🏻

[@DOPEMANCHEW]

There is a screw on the intake that controls your idle as well. It's on the intake right above where the rubber hose for the air filter attaches to the intake.

[@SabrenaGoldmansygaux]

I replaced my dirty air filter and there was a screw in there I wondered why the idle issue happened right after that… also replaced map sensor

[@mindtrap98]

Hello, Thank you for all this information. I own a 99 honda civic LX and I ahve changed my fuel injectors becuase is was have throttle bogg down issue , but that did not fix it. it idles hard and still looses power when you step on the gas. so I am going to change out the throttle body sensor. I want to keep this car, I have had it for 15 years. Best lttle car ever.

1994 Honda Accord Lx here and I have a massive surging/idle issues main when sitting either in park or drive at a light. Things Ive worked on and still havent resolved my issue is spark plugs, TPS, IAC valve, replaced the TB gasket (i replaced it wrong so theres a vacuum leak at the gasket), cleaned the TB plate, EGR valve and port cleaning. gonna try and clean the fuel injectors and i have o-rings for the FIT valve coming in half a day so ill be able to do that also. Wish me luck cause I bought the car with a idle problem :D

[@nielsei]

Your grinding hard bro it will pay of eventually

[@95TurboSol]

My B18c has a high idle (2000ish rpm) but only in the fall/winter, it doesn't surge, just high until it warms up. Do you think it's the fast idle control valve or IACV?

[@TexasHondaChannel]

If you have a Fast idle valve I would heck that first. if you don’t have one use a spray bottle with water and spray around all possible vacuum leak areas and listen for a sucking sound.

[@biocamino_ezequiel]

Same issue in a 97 CRV. Do i have to screw the fitv to the top? I read that this is calibrated in a certain position, i dont want to create a problem

[@carpo719]

I'm pretty sure it's my manifold gasket but I'm having problems getting it out. I want to make sure that's the problem before I get too deep into it. That clamp that holds it onto the engine is a pain in the butt. Those bolts tend to wear down, and rest, and you will need a standard set to find that sweet spot where it fits the Bolt 9/32 or whatever it is. I have three bolts broken off at the manifold, fortunately there's enough to grip onto to get them out of the engine. I just don't want to get too far and not be able to fix the problem or find out it was something else. My car's been sitting for 2 years, every time I fix something something else would be the problem as usual

[@carloscuevas9853]

Sick engine bro. I just got done rebuilding a b18b1 and when I started it, it had a surge to it so I’m hoping these steps will fix it. Thanks bro. Appreciate the video.

[@iDIL53]

My civic 2010 has this problem Whenever the air con compressor cuts in - the engine shudders for a second. I've cleaned the Throttle body and EGR - works only for a day and the shudder came back Engine mountings are ok and no engine vibration during stops/idle if the AC wasn't ON engine only shudders for a few seconds when AC compressor starts (RPM also dropped a hair but steady at 800 after the shuddering)

[@pilgrimhere652]

I have changed all those sensors and valves in a 1992 honda civic, Im gonna check if the manifold gasket is bad. but I ain't selling the nice looking Civic , That's for sure.

[@frankybarra2532]

Thanks bro you help me and saved me a lot of money going to a mechanic and being robbed

[@victor440_]

Great tips thanks you should have mention that if the car does not idle it's probably carbon build up around the butterfly valve inside the throttle body. That can be cleaned off with carburetor cleaner and some q-tips. Like I said great videos thanks for the content.

Hi mate, thanks for the video. I have HRV (D16A) in New Zealand. The rpms go Up and down when i accelerate (1500-2000 or 2000-2500) it doesnt do it entire rpm range when car is parked. I have checked TPS with multimeter, checked IAC valve but no gain. What else it could be??

[@hegeliandetective1034]

Troubleshooting issue, been looking all over forums for weeks, found some tips but still can't narrow it down. 2000 Honda Civic LX, with JDM D15B(non-vtec) swap, automatic transmission. Symptoms, when warm(not cold), coming to a stop sign idle drops to 100-200rpm, pressing on accelerator it pops back up to 700rpm. On the highway cruising, idle wants to drop randomly a few hundred rpms. Almost wants to stall, press on accelerator just a bit more it recovers. Replaced intake gasket, checked timing, replaced MAP, replaced IACV, topped off coolant, bled coolant. Did various idle adjustments, still unsuccessful. Has a header leak, so I'm thinking it might be a vacuum issue. Will be addressing that, but it wasn't acting like this even with the headers leaking. Just received a throttle-body gasket, in case it needs to replace. Replaced fuel filter, fuel injectors, fuel pump main relay, I'm thinking it could be; 1. Vacuum leak 2. Fuel pump 3. Transmission solenoid Open to any ideas on what I should try first, or if you know what has worked on any issues you've found in the past.

[@dadzwag]

What fixed it?

[@yungxwolf6971]

Hey thanks for the video! Really narrowed down my problem, though I have a 2000 accord and I'm having the same issue, only idles in park though. Is that the same thing going on here? Anyone with any answer please lmk

[@joabtrust]

Yes, our 2000 Civic surges when in park, put it in gear and it stops until the rpms get low or near idle.

[@miguelarevalo1489]

Great tips. I'm having issues with my wife's cousin crappy hinda

[@codycastro8083]

When I press on the gas, the engine bogs down between 0 to 20 miles an hour, but once I let off the gas pedal and press on it again, the engine drives normal. I’ve already replaced the map sensor and intake sensor. Do you happen to know what other possibilitiesit could be?

[@shakamuni01]

Does does the the IAC valve run off coolant. I know it is there to heat the throttle so it does not freeze up. but is that valve not controlled by a servo motor, or is it some sort of hydraulic thing? It does sound like the fast Idle is controlled fully by coolant.. Reason why I am asking is I get white smoke only when idling with no check engine lights and valve lashes adjusted. Looked it up and a forum mentioned: "Default Re: 2000 Honda CRV smoking at idle whtie smoke at idle and just after pulling away from idle, exactly what i had when my Idle air contrl valve gasket had gone hard and failed! This gasket is repsonsible 2 things, the IAC valve, but also the seal between the housing, for letting coolant into the throttle body walls to assist with warm up, and if it fails like mine did, ityou end up with a coolant channel exposed to the sucton side of the throttle plate, and therfore, high suction (low manifold pressure at idle) causes it to suck hard and pull coolant into the intake. Another stupid design!" So I was temporarily going to bypass the water hoses to the IAC valve to see if the smoke goes away. Yes I am expecting a bad idle but without white smoke. If it goes away I will know it is the IACV gasket.

[@timothyfrost8055]

I've got a 1998 honda accord lx 4 cylinder and when in park the idle is anywhere from 2000 to 2500 rpm. But what I don't understand is when putting it in drive it drops down just above 1000 rpm

[@RobertaBurkhead]

My 2001 Honda accord not idling and sometimes the engine stops running when I slow down or make a left turn

[@nicholaspetre1]

I have just wiped and cleaned a throttle body on my Accord 2.4 2011 now I have idle issues - the lowest rpm I get while idling is 840 and it is constantly fluctuating between 840 and 1,100 rpms. I just wonder what could possible go wrong that makes now revs go up and down keeping the lower value pretty high at 840? The reason I went and cleaned the throttle body is that my air intake tube cracked and I had to install a new one and cleaned mass air flow sensor as well.

[@chuySG1]

Thanks for the video. Well explained, lot of information. Awesome!!

[@MikeKollin]

IF I take out the FITV while still on the engine will coolant come out? I adjusted it, tightened about 2 years ago while still on the engine and worked like a charm.,.. It was hard but I took off 1 bolt then loosened the other and let the plate drop out of the way and used a flat head to tighten it up... But Now I want to take it out to clean it.... will coolant come out? Or just a little bit? Thanks for the video!!

great vid!. i appreciate this because i’m new to my car but every thing seems manageable. 2 years ago i was taught how to changed my IAC and recently for the second time because of the revving and jumping/skipping in park or at a light. i thought it was my engine gasket leak but that was fixed. thought it was my spark plugs- changed those. yesterday i cleaned the throttle body but while attached, changed my air filter & tube, and unplugged my battery to reset BUT i think it’s time to take off the TB, change coolant, and adjust the idle bypass screw 😢😅. i’m determined now. ty for the tips. side tip: i’ve been reading my car workshop manual (honda crv 2001 ex) it definitely helps with diagnosing the code properly P0505

Could be a cracked block or head. Are you losing coolant randomly or is it mixing with oil?

You should go.to harbor freight and buy a "block tester"for 20 bucks. You stick it in the too of the radiator and it will tell you if there are exhaust leaks in the coolant. Ie: blown head gasket or cracked block. Save you some money before you get too deep

Is this the correct procedure? And is base idle really 750?

Thanks for the video - I was having the similar problem.

[@Mr25Himself]

So I just switched to a 3.5 intake manifold on my 3.0 and my rpm’s sit at 2k rpm in drive & bounces from 1-2 in park continuously, could anybody point me where this might be messing up?

[@Venumousll]

So we have a 99 crv that wants to almost/die after coming to a stop light, or coming to a stop. it idles around 700, timing is good, new plugs, distributor, wires. So are we looking at the IAC or TPS?..or what?

[@EricGlowacki1]

I just cleaned my Idle Air Control Valve on my 99 CR-V and am experiencing the same issue - idles great until I come to a stop or am rolling without accelerating. It wasn't happening before cleaning and I'm about to try the idle relearn procedure tomorrow + bleed the coolant

[@jambangoni]

Same issue with my 99 CRV. I replaced the IAC and it got worse. Reached the end of my abilities and it’s in the shop now

[@EricGlowacki1]

​@@jambangoni @Venumousll Reporting back in: I jacked the car up and used a Lisle Coolant Funnel (Part #24680) and bled the coolant system of any air bubbles. I just let the car idle with the front end jacked up for 20 minutes. Took a test drive and the car continued to almost die out at idle when coasting/coming to a stop sign. I did Honda's Idle Adjustment Procedure and that resolved my issue. I used a scan tool to reset my PCM/TCM, but the Hayne's manual does not specify using a scan tool or even having the reset the anything before doing it. From the Hayne's Manual, Page 1-30 Sect. 28: Engine idle speed is the speed at which the engine operates when no accelerator pedal pressure is applied, as when stopped at a traffic light. The speed is critical to the performance of the engine itself, as well as many subsystems. Before checking or adjusting the idle speed make sure the CHECK ENGINE light is not on, the air cleaner and spark plugs are in good condition, the PCV system is operating properly and the ignition timing is correct. Connect a hand-held tachometer in accordance with the tool manufacturer's instructions. Set the parking brake firmly and block the wheels to prevent the vehicle from rolling. Place the transaxle in Neutral (manual transaxle) or Park (automatic transaxle). Start the engine and run it at 3000rpm until it warms up to normal operating temperature (the cooling fan comes on), then allow the engine to idle. Stop the engine and disconnect the electrical connector from the Idle Air Control (IAC) valve. disconnect the EVAP purge control solenoid. Start the engine with the accelerator slightly depressed and stabilize the idle at 1000 rpm. Slowly release the accelerator and allow the engine to idle. Make sure all accessories are turned off and the radiator fan and air conditioning are not operating. The idle speed should be: 480 (+/- 50 rpm) If the idle speed is too low or too high, remote the cap and turn the idle adjust screw to obtain the specified idle speed. Make changes slowly in 1/4-turn increments only. Turn off the engine and connect the electrical connectors to the IAC valve and EVAP canister purge. Remove the 7.5 amp BACK UP fuse from the underhood fuse block for ten seconds. This will clear any trouble codes from the ECM memory. NOTE: Unplugging the BACK-UP fuse also cancels the radio preset stations and the clock setting. Be sure to make a note of the various radio stations that are programmed into the memory before removing the fuse. Start the engine and allow the idle to stabilize for one minute. Note the idle speed on the tachometer and compare it to that listed on the VECI label or in this Chapter's Specifications. If the idle speed listed on the VECI label is different than that listed in this Chapter's Specifications, use the specification shown on the VECI label. I used my scanner to read the RPMs and I did a 1/2 turn of the throttle screw to get from 450rpm to 750rpm. Currently idling around 750-800 when at a stop. Hope this helps anyone out there reading it!

@@EricGlowacki1 very helpful, thank you. Last I heard, the mechanic had not figured mine out yet so I’ll give this a shot when I get it back. Mine was doing the same thing wanting to die whenever I let off the gas pedal

[@Venumousll]

I took the throttle body off and cleaned and adjusted a few things. Then took off the plate going to the fast idle, and the plastic piece that screwes inward was almost unscrewed completely. I took it out cleaned it valve/ spring and replaced it and screwed the plastic piece hand tight and now it actually idles better at a stop

[@marcuscosta6102]

Thank you! Very great content, it helped me me a lot!

[@terrencecoughlan5704]

I just put it in park and the D still does that like it’s stuck on a certain gear when I drove it to work one day would not change to the fourth gear it’s a 02 lx auto and I have an 02 ex 2 door which I’ve driven to work after getting it from my grandson sat for 4 days then just started acting up

[@adamborowiak4995]

My 1987 honda civic hatchback si started rough idling for no reason. The rpms jump from 700 to 1200. Any ideas other than what he mentioned?

[@cutedogshorts5426]

I’m trying to figure out the same thing for my 91 accord

[@kylerobison1425]

On mine I changed the fast idle and IAC control valve and that went away but I got a jerking and bucking at about 30 miles an hour sometimes before I can’t figure it out I’m gonna redo everything in my throttlebody because I’m sick of it

[@xxd4rkxm4gicxx39]

I got a 1995 Honda Accord EX with an f22b1, car surges on idle or stopped at a light, but doesn’t surge when driving, all i’ve done was replaced the IACV and it still surges, any help?

[@ashleypickle1328]

following. cause same. next step is to check the coolant and TB.

[@itsreamo]

Same issue 1999 crv

[@truthseeker1203]

Clean egr valve and egr passage.

[@truthseeker1203]

Also egr valve and clogged ports.
