For the past couple of years I had been experiencing hesitation (to the point of knock) and sluggishness, but had resigned myself to these just being part of having an older car. Did this simple routine and the difference is shocking!! No hesitation whatsoever, even when it's bone cold. Acceleration markedly improved. I feel like I just got a new car. Thank you, thank you, thank you
Appreciate you sharing
I just wanted to add that I cleaned the MAF sensor as you said and the problem has cleared up amazing I really appreciate this video Thanks
Thanks so much, I love hearing success, appreciate you taking the time to comment
Thanks DannyDIY! Never knew about this sensor till watching your video. My Civic has 140k miles and never cleaned this sensor before. Hopefully after following your guide my car will run like new 😃
Any updates?
Very instructive and useful, I'm having the same issue right now. Thank you!
Appreciate the compliment
One tip; Take the top of the air cleaner off the care before trying to remove the MAF sensor, then with it on a work bench. you can more easily remove the screws instead of all the bending your back and trying to angle a screwdriver in there. Also, one of the two screws was on very tight and i almost stripped it. I sprayed a very small amount of PB blaster on the screw and gave it a couple taps with a rubber mallet on top the screwdriver and then a few minutes, for the oil to drain down to the threads. the screw then came out easy! Mine is a 09 civic and had never had this service done.
Great input, my car is a California car and doesn’t see the outside weather as many others car out there, appreciate your input 😢
Respected 🙏🌹
I recently bought an 08, 1.5k starting idle but smooths out as soon as moving, still need to take the time to clean the body but by applying the logic of the ac brings the idle down: keeping my ac on a low setting when starting my civic and it starts perfectly smooth now
Great info
I recommend you use a nitril or similar glove to prevent that carcinogenic cleaner getting absorbed into your skin. Also doing this away from the paintwork of your car. Otherwise a good video. Thank you.
Thanks for sharing helpful tips
Damn, ive been getting it on my hands for years
@@alejandromorazan3420 And hopefully you have not lost too many days due to that exposure. Live long and prosper.
My 08 stalls off the start It doesn't do it all the time. I have a brand new MAP sensor and i have no codes I cant seem to solve the issue
The same problem I have only corrected when the car is restarted
I hate how the new Hondas have tiny little Phillips head screws. I miss the normal size ones.
Love your videos Danny ….question what oil brand do you recommend on a a 08 civic 1.8l
This is what I’ve used in my Honda vehicles ever since they were brand new, it’s served me well : valvoline full synthetic Advanced saw 5/20
@@dannysdiygarage appreciated, keep up the good work 💯
How much did it improve the MPG's and power going uphill? I've never heard of it but it seems like it's worth doing with minimal risk. Thanks for sharing
Your improvement will depend on how dirty your airflow sensor was
Hi Danny, what was your before and after MPG on your civic and element after doing this?
Mine wasn’t dirty, I do this every year, so my mpg on the Element didn’t change, however on my Civic, i noticed a 2 mpg improvement cleaning the throttle body, airflow sensor, changing the oil and air filter and aired tires to 35 psi, my Element tires im running 42 psi, the ride is a little stiffer than when I ran 35, but the mileage is better. My all time best was 31 mpg on a trip, i track my mileage every fill up, I usually averaged 24 to 25 city hwy mix, I believe I have 130k miles on my car, hope this helps
Which year models of civics have that removable mass air flow sensor? I have a 2006 dx which idles fine but as I'm say 50 feet from a stop, it occasionally dies which as you know can be very dangerous loosing you brakes in motion.
A 2006 should have this
How much time to leave it to dry after spraying.?
10 minutes depending on weather
How often would you recommend cleaning this?
Recommend ever 60k,
Good day. My 2008 honda civic misfires at idle only, drives perfectly fine otherwise. Changed spark plugs and MAF sensor. There are no vacuum leaks. No check engine light. What do you think is the problem?
But not driving 50mph up a hill, maybe Valve adjustment? I have a video on that,
@dannysdiygarage it drives up the hill pretty good, has a lot of power especially when it hits vtec, its just that it idles poorly
I have a civic 2013 and when I remove the clip of MAF sensor the car does not shuts down does that mean its bad or needs cleaning ?
When you say clip do you mean connecter? If yes? No it only means it’s disconnected and the computer sets fixed value, hope that makes sense
@@dannysdiygarage yes hopefully because it triggered problems after I cleaned the throttle body and changed air intake tube because it was broken after that it felt like the rpm was a bit high and also triggered some lights once so I figured it is something to do with the MAF sensor I might be wrong because I did not clean it not did the previous owner might have considering the condition of throttle body carbon deposit.
What else could I clean this with ?
Only use what I suggested, it’s safe
Hey Danny. Is it necessary to let it dry before reinstalling?
It should dry before starting
Thanks for the quick response, Danny. I appreciate all the great content you have put out. It’s very helpful for me and many others.
I have a 2013 civic that hesitates when warm when i am around 50 mph and seems to also hesitate when warm at a stop. Can this be the issue
If it’s hesitate and not a chug, like miss-fire, this could be the issue
I have a question I just installed a intake on my 2010 civic it ran perfect with the stock air box but now it’s throwing a code for throttle spring malfunction I can’t seem to find the issue it runs for 5-10 sec then shuts off also my check engine light is on
What’s your question? I would Put it back to stock, or pull the code and diagnose it, do you have a code reader?
@@dannysdiygarage yes I hooked the code reader up an it said throttle spring malfunction
If it didn’t have a issue before installing the intake, back to stock would be my direction,
Also, if you give me the code I could look up diagnostics, unfortunately not till Sunday
@@dannysdiygarage that’s what I was thinking to see if that’s the issue but so far I think it is
What is the white silicone dot on this sensor. Is it OK without it?
Sorry, I’m not sure what you’re referring to
@@dannysdiygarage
Sir, if you observe closely you will find it.
I don't have option to send you a pic.
Anyway, I appreciate your response.
Stay blessed and healthy.
Went to do mine and one of the screws had been stripped out by some previous owner. Guess I'll take the air filter top off and spray in there best I can. 😢
Do need to do a video on removing stripped bolts
Hello, I have the same issue on my 2013 civic coupe 1.8l, I have replaced the intake boot, cleaned the maf sensor, replaced air filter, still no luck..
Sorry I don’t have a solution
Try cleaning the throttle body and the idle air control valve. That fixed my issue
How did you go?
Check spark plugs.
@@ceegee3514 where is the idle air control valve located on 2013 civic 1.8L?
Am having 2010 honda civic 1.8 l 4 cyl automatic not giving proper mileage.
Fuel Tank Capacity 50Liter
It will give 560 kilometers if I fill up fully for the long travel.
When am drive inside the city for full tank its giving me 290 to 300KM
These are the steps that I have done.
1. Clean the mass airflow sensor.
2. Clean the throttle body.
3. Clean the plugs.
4. Changed the engine oil and gear oil.
5. Clean the fuel filter.
6. Clean the fuel Injector.
Please assist me with this.
I'm on the same boat with my 2010 honda civic 1.8 prosmatec. Let me know please if anything worked for you. @Danny your help needed.
Can i use for this WD 40 spray for cleaning ?
No, only use what I suggest
😂
Would wd40 work to clean it?
Wd40 will destroy it
Can i use WD-40 for clean?
Absolutely not, use what I recommend only👍🏼
Are you serious?
My problem with our car is that midway driving there are times where there will be no power/acceleration even if I step on the gas pedal several times but will cruise. We have a honda civic fd 2.0at. Also after that the car would judder everytime you change the gear all the way from Drive to Park. It will only be solved by turning off the car and starting it again, then there will be power/acceleration again. Do you think it's the same with what you had in this car in your video? If so, can you teach me how to fix it please?
The car should have set a code, go to the auto parts store and see what code is in it
Did u fix this ? I have same problem
Look for a tear in the intake boot after the MAF sensor or near the sensor I had this problem twice with my civic 2012 if air gets to the engine and it's not regulated by the MAF sensor it will act just like yours did and may or may not throw a code... good luck
@@miguelbonsu2112 read my comment.
I cleaned mine and it didn’t really make a difference if anything g it’s getting wkrse
Definitely isn’t going to get worse mileage
Another option, save the $25 on the crc and just splurge on a new maf, just sayin
Jeff appreciate your comment, That would also work, but it’s $10 not $25 👍🏼
I put a new air flow sensor in my 2012 Honda Civic why is it still sputtering
Sorry Bill not enough information for me
I put a new air flow sensor in and i put 02 censored and my car still hesitates
when I give a gas
What I'm asking is is there's something else that you think I put a new air flow centering I cleaned it and it still sputters
Hi Bill, I’ve been traveling through the East coast the last couple of weeks and haven’t had much time to check comments, sputtering on take off, possible miss fire on take off? Remember Bill, without me being there experiencing the problem and doing diagnostic testing, these are only guesses, try holding the brake pedal down so the car won’t move and putting the car in drive and hold the rpm around 2000 rpm to load the engine, does it miss or sputter, if so possible plug or coil issue, you can also try this, unplug the airflow sensor and drive it, is it better on takeoff with the sensor unplugged?
I assume you have no engine light on? If you’re engine light is on 1st pull codes, you should also check to see if there are any codes which didn’t turn on the light
Sorry for the late reply, I’ll be traveling for another week or two
I have the engine checklight on the schedule light on and the power is Jerry light on the vehicle starts up idle is good it is when I'm driving around 25 miles an hour when I give it gas it's spotters other than that it runs good You have a phone number I can contact you
