So extremely rare to see on UA-cam someone explain something without the fluff and unnecessary drama to make you watch a 10 min video. Give this man a GOLD UA-cam play button NOW. But the sad fact is UA-cam reward those who game the system, weird isn't it.
My first step is clean the throttle body and plate. I have no doubt this can cause the sticky acceleration. Throttle body spray cleaner is not real pricy
Agree, always like finding simple little videos like this that give me a gist of what to do. Though, in some instances, longer, more drawn out *tutorials* can be appreciated
ABSOLUTELY. Straight to the point.
i can say i learn from this guy he is rare alright.
Unfortunately, it's not true. Like so much youtube. Now, 20 people watch this and make their own videos, creating more bull 💩
That is how you do it. No stories, no wasting time. To the point! Thank you... Like has been earned.
Short and straight to the point. No fluff. Thanks
I have been trying to figure out what was wrong with my wife's Malibu for months. Came across this and I will be damned. Changed MAF sensor on 2011 Malibu and now it's purring. No engine codes. God bless you for helping discover the fix and for helping me save money.
I'm gonna be 100% honest and say that I figured pulling the cord on a sensor in general would stop the engine anyway. So I walked outside all skeptical, started my truck, pulled the cord and the thing kept running. You win. Thanks.
I'm going outside.... 🤣lmao
The same here i tried on the 2008 suburban unplugged the car kept running. I bought a new maf sensor installed it unplugged the car kept running. 🤔🤔🤔i wonder do you do this on a cold engine or hot.
@@SamSam-on8dt each car work different most of the cars will keep running other dont...if your car keep running BUT you got all the loss power back and I mean like no issues then provably it is bad / bad groud or broken wire must see wire near connector 🖖🏿
Hey Paul you shouldn't be putting videos like that's up a lot of people will be wasting a lot of of money. I don't know if you're a mechanic. That's not how you test an air flow sensor
Just came back from my garage 😂 my car kept running sooo? New maf sensor I guess
Told exactly what I needed to know and took less than 2 minutes to do it. Bravo sir.
Wow..! tried exactly what you said step by step.. it fixed the car, I couldn't believe it at first. so we tried the experiment again, same result-- this repair saved us hundreds!! Thank you for taking the time to post this video!
Thank you a million times for this vid. My 2004 F250 5.4, bought new, was having issues losing power uphill and under load at 85K mileage. Took it to four mechanics over the last 1.5 years. No one could figure it out. One told me the truck's engine wasn't powerful enough and that's just the way it was built. Not! I've driven and towed with this truck since 2004 and never before had this problem. The most recent mechanic at a Ford dealer said it was the transmission and wanted to take me down that rabbit hole but I intuitively knew that wasn't the problem. I had already taken it to a good transmission specialist and he found nothing wrong with the transmission. But, then I found your vid and, sure enough, the sensor was bad! $140 cost to replace and I am now driving with no power loss and ability to tow my horse trailer up hill on the Interstate beautifully. Just as it was built to do!
That’s awesome.
Amazing.
my mechanic told me my cam is broken on my ram and said a used engine would be better, so much bullshit from these highway robbers.
Dang you found the solution, an still got screwed for 140 ! They cost only 22- 50 dollars great tho
@@jwillzcommonsence8870maybe if you get aftermarket BS. I ordered a Duralast and it came all mismanufactured and in horrible condition for $99.....I ordered the FACTORY OEM mass air sensor directly from Mitsubishi for $150 and it came in PERFECT matching condition and my car now runs much much much better, almost like new...... 244,000 miles on it!
Thank you for this for this quick simple video. I ran a code saying my CAT was bad & my mechanic said to change the MAF first. Your video confirmed that the MAF needed cleaning/change. Thanks again
Easy to clean?
Another secret that Dealership auto mechanics dont want you too know . Thank you !!! 👍👍👍👍👍
You saved me from headaches. I thought my transmission was the problem, the dealer told me I needed a new fuel pump, and my brother said I needed a tuneup. After watching your video I tried it out on my car, found out it was the MAF sensor, ordered it and my car works like a new one. Thanks!!
I I a 2nd 3535erq5q33q444
The dealerships will scam the scrap out of u
Did u install it yourself?
Does this work for all cars
Also unplugging the mass air flow sensor while the car is running on some cars will cause the car to go into a test mode and then u may have to see a mechanic to get out of test mode
After spending 700+ dollars on ignition coils plugs and wires I found this video. I was at wits end. Thank you for being so to the point and concise.
So it solved the problem?
Well at least next time you have a problem, you can rule out all of the things you replaced lol
Fr i did the same i replace all the spark components coils, plugs, fuel injectors, valve cover, and fuel regulator and still threw a cyl 3 misfire. Got the sensor and ran better than it ever did made the light go of. P0303 code gone @Ron.Swanson.
Don't really mind throwing parts at her I'm gonna keep her forever
@@JohanAguilar-kk9sp I replaced my MAF the other day after doing googling for 3-4 days on why my 4Runner was not accelerating well when I was pushing on the pedal. It seemed to have fixed the issue.
Hey thank you very much for posting this video. My check engine light has been on for a few days now and I just did this test and confirmed that the mass air flow sensor is bad. You're right, it was very easy.
Thank you again for posting this video and showing us how it's done!!!!
This was awesome. Thank you so much. I can’t believe how easy that was.
im impressed by how you explain something like this quiet simple without any nonsence and taking ten minutes to do so ,, so well done , i would think you would make a good doctor or teacher of any subject in front of a classroom of kids
I cleaned mine, and it worked for another 5 months, but the problem came back. I performed this test and the engine kept running. Thank you for creating this video! So at this point it is likely to be a bad MAF sensor.
Thank you so much. Saved me alot of money! My car didn't have a check engine light but watched that video and got my car running great now
Simplest explanation. Had to get the obd to find out it was the sensor, but I remember my van not shutting off when I disconnected it. This wouldn't saved me a lot of time and money. Thanks for the helpful tip.
Hi my car was stalling at stop lights and I unplugged the mass air flow sensor plug and plugged it back in again and now my car is not stalling anymore 👍🏻🇦🇺 thanks so much for this video.
THANK YOU...for taking the time to explain this. I am having the exact issue with my auto, this will save me a lot of $$$$!!!
Awesome man spent 190 dollars at a corner shop and couldn't find the issue on why it idles roughly, I should have started with UA-cam to find my issue myself. I came across your video third video from The View Bar I tried it and that's exactly what it was. From now on I'll be diagnosing my own car using UA-cam
Also make sure your throttle body is clean. ua-cam.com/video/cOAYWVBfuek/v-deo.html
Excellent video, quick, and to the point. You didn't do alot of talking. Thank you.
Rey DeGuerra Exactly I love this, I make videos myself and try to do this, because I hate people who run their damn mouth for 15 minutes for a video that could've been 3 minutes
I so agreed u and Chris fix the bomb very awesome no repeating yourself or telling storys
You are a gentleman and a scholar! I had the good old multimeter out and ready to test it and saw your video, beautifully simple!!
My mechanic is out of State so i have to Rely on You Tube to fix my car/ thank you for sharing this information Sir i appreciate very much 🙏
Thank you to all UA-cam mechanics. You've helped me out so much. This video in particular was very helpful. Keep it up!
Love this video sir. I used it to check my cars MAF sensor. Luckily it was still working. Love the simplicity.
Your 2mins video has given me a lifetime of knowledge to share.
Yes shared to two friends 👌
Straight to the point. No BS
Nice one mate 👍
👍😊
Thank you, this is the easiest diagnostic i have ever seen among other videos, would give it a trial and find out !
I did this because I found your video... I think you saved me $600 because I was told it was my computer!!! Thank you!!!!
Same here
You are gorgeous😍😍😘😘🌷🌷😊😊as simple as that.😅😉😊

Wow it works now after 4 years of suffering that low voltage. Much appreciated for your sharing Sir! Have a very merry Christmas to you and all!!
I've been an auto mechanic for over 20 years. Many of the problems I see daily could have easily been avoided by simply following the vehicles maintenance schedule. I use a program on my computer called Automotive Wolf car care software to keep track of all the maintenance for my 3 cars, a truck and even a generator. It automatically can send you text message reminders when any type of service is due. Two of my vehicles have over 200,000 miles and have never needed any repairs. Want to save money? Follow your maintenance schedule!
Great instructional video, simple and straight to the point.
thank you for making my day much easier.
Just like testing your alternator to test that unplug the battery when the car is running if the car stops your alternator is bad. Great job
Thank you so much for getting to the point explaining everything quickly that is what makes the videos helpful most people don't wanna set through a twenty minute video with advertising and alot of bla bla bla thanks 👍!!!!
Thank you for sharing this video/info, this is very helpful for people who don’t know much about cars and engines...-like me..I appreciate things like this.
This video though is short,simple but very informative and educative,thanks for the good job.
HI from NZ. Thank you for sharing this short but very helpful video. I'm going to test my daughter's car for this problem. Thanks so much!
Thanks so much.....I've cleaned everything on a 98 Marquis....only ran for 3 second s......I unplugged massflo sensor...,. STARTED RIGHT UP
thank you this was spot and the crazy problem that fixed my moms car! thanks for making such a simple but amazing video
At last a Video of the simplest form with no bullshit! Keep up the good work!

This video stands out as one of the finest instructional resources on UA-cam. It wastes no time and gets right to the point. Initially, I believed my transmission was experiencing problems, so I attempted to resolve the issue by changing spark plugs and the fuel filter, but to no avail. However, upon discovering your video, all of my troubles were alleviated.
hi did you have trouble with a shudder noise like miss fire
When you thought your transmission was bad did you also try new brake pads and rotate the tires?
Thanks Paul , you're a good dude ! And may God bless you !
Lifesaver! Thanks brotha
Thank you sir. Succinct and to the point. No fluff, only concise, usable information. Subscribed.
Your vid just solved my sputtering issue on my truck, thank you!
🤦♂️ where was this video when I needed. I had this issue last week didn't know how to test it. Now I know. Thank You.
Ck'd it with my OBD II it said flow restriction. I thought it was the cad converter but saw this video wow! fastest diagnosis ever. Thank you!
Mine is saying p0403 EGR vaccums solonoid . But when I pull this plug it doesn’t shut off
This man needs a medal, finally a simple to the point video ! I appreciate it my friend
Lol wtf I just told a mechanic that I tested my MAF sensor like this & he said that’s not a good idea
@@steelokey anyone who can make money from you will tell you that. They don't want people to find the easy way around things.
@@gazlp1 lol right, i found out that was my problem, bought an OEM one cause the one the previous owner/mechanic shop had put in a aftermarket part. 🔑

I was going to take my 2008 Pontiac to a shop to put the mass air flow sensor on a new one and a emission evaporative position sensor showed a leak that I know where’re it is exactly. But the shop wanted to charge me $700 for labor. So I looked on UA-cam. Thank you cuz you saved me money on the mass air flow sensor. And now I have to look at how to fix the gas air leak. It was so easy to put on a new Mass airflow sensor.
By the way love your video, u made it simple & to the point & I'm sure you saved a lot of ppl money...
This is a great job of getting to the point and creating a detailed and concise solution for the average person. Thank you so much.
Go f yourself. U dont care about me or my family. Listen to urself.
And thank God it was not filmed in Nerd Vertical!
Can either of these cause a surging? MAF sensor
One bad plug wire
clogged catalytic
Converter?
I don't have a Check engine light on.
Amazing test! THANK YOU!
Ive never subscribed to a channel so fast.. straight to the point❤
Great video. I have watched countless videos, and this one is directly to the point.
This was real helpful to me thank you
This video saved me! My car didn't do exactly what he said but it gave me my diagnosis
Great job on this vid mate.
Good info without all the fluff.
Thanks 👍
Very nice. Simple and straight to the point! No fancy diagnostic tools needed! Sometimes just diagnosing the problem is the hardest part! Wish I would have know this last year but MAF sensor wasn't too expensive for my 2002 Rav4. Only about $32 off Amazon!
Simple and best solution.. awesome
Simple and straightforward. Thank you. My Volvo S40 needs a new Mass Airflow sensor
Hello I have a volvo S40 too. What symptoms were you getting and did you fix the problem?
Simple and easy! Thank you!
Thank you so much for this video! I'm glad I believe in doing my homework before just going to dealerships. Check engine light came on Friday, had the reading done and it came back as the MAF sensor needs replacement. Did this check on Saturday and my car kept running yet acted as if it was going to stop but kept running.
I cleaned both my sensors with CRC MAF Sensor Cleaner. Drove it around today and my vehicle rides and idles sooooooooo much smoother now! I sure hope this cleaning resolved it and I don't need to buy new ones. Again, THANK YOU SO MUCH!!!
Great information,thank you so much.I unplugged this sensor and was worried about if vehicle would reset itself,so it's 20 mile's.Thank's again.

Benito Juarez iiii
Great video man. Definitely helped. No messing around and useless information.
I was amazed that my terribly running recently purchased 07 pathfinder stalled slightly but kept running. Does this definitively mean that the sensor is faulty? That would be an amazing quick to a problem that’s been taking too long to figure out. Thanks for the awesome straight to the point video.
The best video, straight to the point, no talking bull....t.Thanks.
Great information.
God bless you and thank you for the sharing.
Greetings from Pakistan
YOU ARE THE MAN!!! I have trouble to figure out if it was the MAF or something else... i did it and my car keep running as u said so my MAF is bad... thank you a lot....
did you replace it yet and its working?
@@gingerwallets8000 2 years later lol
@@Piercemxpx hes no better not replying to me and its already been a week pft how rude
If the car keeps running does it always mean the maf is bad?
Mines kept running today thanks also
Thank you so much Auto shop said transmission was bad. I came home and changed plugs, battery and tried this. It kept running so ordered a new one and air filter.
god bless you my friend you just made my hollyday. thanks a billion
I absolutely love this test.. I just wish my MAF sensor was in a easy place to reach so i can perform this test.
Wow, after months of trying to figure out what was wrong with my car - talking to and taking it to many mechanics this is the answer I have been looking for. Thank you soo much man, I can now freely go travelling my home country!
What symptoms was the engine giving or just the Check Engine Icon TURNED ON ? TY
All the mechanics had to do was put it on a scanner and read the codes. Some scanners tell exactly what is wrong
I have Cx5 2014 sport, 6speed, 135,000 miles, I've had spark plugs & tune up, misfire coil wire #2 changed. Ran well, for two weeks ago, I recently noticed some hesitation & jerking again, upon stepping on the gas going up a hill, was only able to go 5 to 10 miles smh. I ordered the MFA oem part, and hopefully, this will fix the issue. The car has been to 2 garages, totaling $500, and I've heard hope its not the engine or something else from them. Thanks for your video❤
Same story here with a 2016 Kia Soul+. One lone misfire on cylinder #2 code, that never came back. So no codes to go on for 6+ months. Changed plugs, coils, battery, filters, cleaned fuel injectors. Took it to 3 repair shops. Spent $$$$$$! Last shop said maybe it's in Limp mode with no code? Or maybe it's the transmission? Called the Kia dealership twice $200 to put it on the first level code reader, $+++ after that! Kia even said maybe it's beyond repair! 😢 At 133,000 miles!? It went from great car to 40 mph tops, then to 20 mph tops over 6 months. Won't climb the smallest incline. Jerks, rough idle, can't press the pedal down even halfway way or it starts knocking under the middle passenger's side. Barely no forward power, and jerky Fuel economy dropped from 30 to about 10 mpg. Runs best upon starting for the 1-2 minutes between "cold" & "neutral". Doesn't go over 2000 rpm. Seems like it doesn't shift out of second gear. But no codes! Just a quickly flashing oil light after it's been running for awhile, but I've checked the oil dozens of times & it's always full. A lot of weird symptoms! I'm gonna try this MAF test & see if it's that!
I just tried this on my 2003 Audi A6 2.4 and the engine din't go off. Thanks a lot, mechanics would have charged me an arm and a leg for this. Truly appreciate it.
Did you get a new one ?
Straight to the point and very simple keep up the good work Good video
Thank you for the information, it worked textbook perfect! I changed mine out on a 98 Honda Accord and it fixed it. Back on the road! Your video was short and to the point, not confusing. Appreciate Ya!
did u experience any car symptoms before u changed the maf sensor...
Yes I did , it was running very rough as I was driving down the road. Acted like it was missing and was going to stop at times. That fixed it. But if that doesn’t fix your problem it could be another sensor.there are quite a few of them that could make it do the same thing.
@@Jimbo7303 98 it works, but after 2000 no more so this test is for older cars, use live data and you know for sure what the problem will be.
Thanks. Just purchased a new mass flow sensor and installed.
Clicked liked and subscribed to your channel. Much appreciated.
Gr8 advice and after cranking and disconnecting the maf sensor the car did stop so thanks for the advice🙌💯👍
This is the best money saving video ever THANKS SO MUCH
Damn. I just went outside and unplugged everything on the airmass censor and its still running. You might of just saved me. Thanks
Thanks for the video. I had this same problem with my z4 e85 three times already within a week. The mechanic did mention last Jan 2023 that it may go bad and to replace it but mind as well clean the MAF first to see results.
After cleaning it, all was good until just few days ago and today, I started to have that same problem and this time it went dead on the road. Had to park on the side to restart the engine again.
Watched a guy in another video drive through town with a computer. Total waste of time. Thanks for the easy to understand concise and to the point video.
Great test and everybody loves it..question did the engine light go out after you plugged it back in ? We need a Coronovirus test like this.
I did this test after having issues with stalling at junctions, didn't have an engine light on before, but I do after doing this.
i pretty sure my two cents wont matter,but why cant all or even most diy videos be this simple.you are straight to the point.thunbs up my man.
I need to buy one because engine keeps working when I pull connector. My mechanic found problem in MAF sensor using diagnostic device. So you are right. Thanks a lot for the video.
I bought the same exact denso from Amazon for my 2003 Corolla with 150k miles works awesome just installed it yesterday
Hey dude thank alot for make my this. You're cooler than Eskimo fingertips.
this comment rocks
Yeah yeah you're like like super cool dude get it like super cool
This is very well explained and it is important to know this also sometimes you may not need to replace your MAF Sensor so you can buy a special Mass Air Flow Sensor Cleaner which is a spray and spray the metal wire part of it, you can watch videos on how to clean MAF Sensor.
If the car doesn't turn off your maf sensor is bad or the connector is bad
if u have a rough running engine when the sensor is connected cleaning it might fix it but if the engine doesn't stop at all when u dissconnect the sensor then your maf sensor is bad
Because maf sensor cleaners clean the sensors and they work only if the sensor was already sending signals or working poorly atleast
If you pull the connector and it turns off then the sensor is working "even if it was working poorly it would turn off"
It will stay running if the sensor is bad
This is my thought about maf sensors if anyone thinks that am wrong pls correct me 😁
The idea of Mass Air Flow Sensor cleaner is not to fix a faulty MAF, it's to KEEP IT CLEAN so it doesn't crap out.
Another sign of the MAF being dead is the car running rich, and I mean halve your fuel economy rich, blowing fuel smoke by the bucketload and getting worse as the throttle is opened more. Plugs often foul and cause misses within 50miles or less.
Contrary to popular belief due to a "Pimp my mum's car" kids show from England, check engine light doesn't necessarily just mean a faulty O2 sensor! 😂 😂 😂
Thanks for sharing the experience.. Simple but Helpful & Time/Cost Saving
Praise God brother. May your video continue to be a gem of knowledge to the masses, Lord willing.
Check eng light came on a couple days ago. Just came across this vid i'll check it out when I get off work. Thanks for the tip.

Also change your air filter... thx man, great 👍
Helped my Grand Marquis SO WELL
Thank you!! NOW I can ask all the right questions.
I agree with the comments, good video, I would like to add one detail if I may. Another option is to purchase a can of MAF Sensor cleaner, and I only say this because some of those sensors can be expensive. I've had excellent results with the cleaner, and no disrespect intended to your video.
Agreed. Usually a simple cleaning does the trick. Not always, but it's good maintenance to do. At a minimum, it can extend the life of the MAF.
WOW I have now gone through 2 and prob 2 hours of research to have you simply unplug it... Your on point.
MILLION DOLLAR QUEST.
For both of you Scholars, if the engine doesn't Is cut off and still runs which would means my sensor's bad, I could still possibly clean it to salvage it???
I did try to spray a bit of cleaner but still the same problem, any further suggestions aside from the basic spray cleaning?
