Scotty Kilmer . What well be a the problem on a 02 gmc Sierra slow start on drive? When am in the light i dont to hold the brake cause doesn't seem to move like it usually move on drive? Maybe tranny ? Thanks
Hey Scotty I have a 2012 Kia Soul 1.6L. Do you know if I have a MAD? I see a small box after the air filter box. Is that it?
Scotty Kilmer b
I have a 1990 Buick LeSabre, where is the M.A.F. Sensor on a 3800 I (one) series V6 engine? Will a can of air dry the sensor or compressed air only?
No
Probably the best mechanic channel on youtube.
+Sparckman I would say this too. I have seen many and Scotty is really good.
the best mechanic, others spew too much unnecesarry bullshit to act fancy
I personally like Chrisfix more but Scotty is second
Chrisfix is my go to as well! Scotty is a good one too.
Jonathan Peoples I watched Scotty first.
I'd recruit them both for the UK top gear show.
Scotty, following your instructions I cleaned the MAF sensor in both of my Toyota Tundra trucks for the 1st time the other day. The entire process was easy, neither looked dirty but both trucks are much more responsive now that the sensors are clean. Thank you!
Scotty, I bought a 128000 miles car, and I started watching all your videos to get it in great shape again. I used this hint and cleaned the air flow sensor. I just can't believe the improvement that I got!! I am overwhelmed! Seems a new car. Thank you man! REV UP YOU ENGINES!!!!
Don't be tempted to do what i did. After done cleaning the MAF i saw the O2 sensor connector dirty with oil. Unplugged it and cleaned this one too, with quick drying no residue contact cleaner spray (the WD-40 specialist one). Long story short, i needed a new O2 sensor because the old one started sending a very low voltage to the ECU and made the engine run so rich that you could see gasoline dripping from the tailpipe. I then learned that automotive O2 sensors need reference air to work and they source it through their wiring (not kidding). So the cleaner took the place of the reference air in the wires and the O2 sensor started reading lean. The O2 sensor was getting very old but this one was an expensive mistake nevertheless. The new one is making the car run much better than before, though.
This worked GREAT!!!!!!!!!!!!!!!!!!!!!!!!!, did it just like you said, and then cleaned the Throttle Body too, like you said in another of your videos, on my 99 Mazda Protege 5 speed, and now it idles much better, and absolutely no hesitation anymore, and it runs GREAT!!!!! Now!!!
Thanks Scotty
Bruce/ Milwaukee
I swear, when ever I have issues with my car, or I am just looking at random car repair videos, I always see you have a video for it.
I really appreciate all your videos, Scotty. Thanks to you, I had the confidence to remove and clean my throttle body and mass air flow sensor, as well as replace my spark plugs. My Mazda runs great now, and I saved a lot of money doing the work myself.
Scotty, I buy, trade cars off Craigslist, and it seems like every single vehicle I pick up you have a video on the issues involving the vehicle, and I end up fixing the problem based mostly on your video info. Thanks!!!
This video saved me so much money (and frustration if I would have seen it sooner). My 95 Subaru Legacy kept stalling out while I was driving, and cleaning the MAF Sensor with some Iso-Alcohol fixed it right up. Can't believe such a simple problem was causing such a catastrophic failure. You are the best, Scotty!
just stumbled onto this fellows videos..GREAT stuff!
perfect blend of humour, timing, dialog/explanation....
LOOOVEE IT!
I am a novice to auto repair, but thanks to your videos, I saved a ton of money. Thank you sir.
your attitude makes we wanna start working on stuff I love it
like that...

Why ty scotty kilmer
Well Scotty Kilmer much better lol
Seriously, this is the most helpful and best produced repair video I've seen. Also, this guy's energy is awesome. Can't believe I just discovered this channel after years of CZcams guided repairs on my cars.
You make your work enjoyable and simple. Feels like I want to do this everyday lol. It does suck sometimes when you don't have all the necessary equipment that is needed to get the work done. Thanks a lot for the tips.
Scotty, you deserve a billion subscribers! All of your videos are always helpful and informative. thanks for your service, have a wonderful day!
LOVE SCOTTIE! His video's have saved me alot of money because I do my own work a s yes I'm a 46 year old grandma!
I’m glad my buddy recommended this channel to me . Hes easy to understand and got charisma. Great video thank you Scotty !
have a wet and dry compression test done of the engine while you watch an honest mechanic. If rings are bad, nothing you can to but replace the engine, or just drive it till it drops which can still be some time
Love your videos. After my truck kept stalling on stops I freaked out. I watched your videos about cleaning the throttle. My truck purrrs like a kitten. Thank you for your wisdom and kindness.

I am hooked on this man cause he has 46 years of being a mechanic,altho i have a 01 Toyota Corolla that gave me 12 yrs stress free drivin [ 124,000 miles] . I still got a thirst for knowledge from Mr Gilmour to maintain my car to last even longer. Keep up the good work sir!
Came across your videos looking to fix “stuttering while idling” and found a gold mine. You the man Scotty, keep up the great work. New subscriber!
@Lionel Melvin yup we’ve finally found a mechanic with decades of experience who isn’t afraid to tell the truth. He’s a good person too, hence why he’s been married to the same woman for over 40 years. Some people never stay married that long. Good for Scotty. Been watching him for officially 21 months now @ 14 years old.
Genius 👌, I already figured thats why my car wasn't accelerating but now I know for sure. Thanks Scott 👍
THANK YOU. My 2003 Ford Ranger is now acting like a new truck. For the price of a can of CRC Mass Air Flow Sensor Cleaner.
Yes, that is true, I could only recommend them for non MAF sensor vehicles.
Great video. Good lighting, volume, editing and no extra BS. Thanks!
I like this guy, he’s likeable in this cold world!
Facts, I watch him even with out car trouble. Positive energy we need more of it.
try my video "how to clean fuel injectors on your car" that often stops it. If not, pressure test the fuel pump.
depends how much you want to spend and what features you want. go to an auto zone and check out their low and mid priced scanners, they can show you what each one does.
Thanks Scotty, great video and exactly what I needed to fix my daughters 2009 Vauxhall Astra 1.6 Sxi. The MAP sensor seems to be moulded into the actual filter hose on this one and it’s a tiny little thing but, you can see it from the air filter end and reach it with the tube. I used WD40 Contact spray (which specifically mentions MAP sensors in their advert). It worked but, didn’t evaporate. So I dried it out by running a hairdryer through both ends. Thanks Scotty
You are a legend Scotty! 👌 Cheers all the way from Australia
You make all of this so much easier and STRAIGHT TO THE POINT than so many others on CZcams, subscribed!!
Thank you for being here and sharing . Love you, brother.
any extra air or not enough fuel reason can do that. But, on that model, often a leaking intake manifold gasket on the number two bank of the engine does it
Really great rhythm and pace to the video. I haaaaate when simple DIY instructions are drawn out over too much time.
Willy Lamb not only that, they're also wasting their own time making a 1 hour video
Your a cool dude...
Thanks for video
I had the same problem in my Honda City. It's a sedan version of the Honda Fit available in my country.... Got the air filter element disassembled and cleaned mass airflow sensor with a cleaner and viola!!! The vehicle pick up has improved. Thanks for this tutorial. Couldn't have done without it.
you can just plug the egr valve system and see if it stops, then it would be that. Unfortunately those hdis are very complex electronically and you really need a dealer level scan tool to find any culprit for that problem though.
My 98 Tahoes check engine light came on this morning when I was on the freeway and my truck started to loose power. P0102 code came up. Would the MAF sensor go out just like that? It was driving great, then all of a sudden starts bogging.
Do you have to reset the ECU or will it relearn over time?
usually takes either a certain amount of mileage or time.
You can reset if it didn't work the light will come back within a few minites
I had the battery disconnected so everything reset anyways
After 80k on my 2008 Jetta 2.5, never thought to do this until I saw this video now my car purs smoothly on idle and acceleration is back and better! Thanks Scottie Wish you well have a great week Sir!

GREAT JOB SCOTTY!!!! Smart, quick, and oh so EASY!! I will recommend you to everyone!
Was hard to believe the other day in the auto parts store. That mass air flow sensor cleaner is $11.00 a can!!!
+George W You surely got ripped off man! CRC brand is the best $4-$5 max
Thanks Carlos, I'll look around at other auto parts stores. It was that Price at O'Riley's... On clearance of all things.
+Carlos Rios I've always used carb cleaner with no issues
+Carlos Rios For the small can. The 11oz can he shows in the video is usually around $10.
i paid about $9 including tax
A few years ago I decided to use some Sea Foam on my 2001 Corolla, shortly there after my check engine light came on. It give's me the error for air system or something, can't really remember exactly. I've gone in and cleaned the MAF a few times but the engine light didn't go off. I've heard other people that used seafoam that say it blew their MAF sensor, just wanted to get your opinion on this, thanks.
PS, thank for the video on Gumout multi-system tune-up. My car runs smoother and my speedometer light, that has been out for last 5 years, miraculously came on after using gumout. Have no idea why this would happen, but I'm not going to complain.
I think the seafoam has probably attacked the MAF sensor. The sensor wires are extremely sensitive which is why you have to use special MAF cleaner (even WD40 can kill them). You probably need a new MAF, you can buy them for most cars about for $40 online. When using seafoam you should always spray the cleaner in after the MAF or take the MAF off the vehicle. The vehicle should run without the MAF connected but fuel economy will deteriorate and some cars may go into limp mode/safe mode.
Forename Surname no one has ever been able to tell me exactly why you have to use MAF CLEANER only on MAF's . Besides there are a lot of different MAF's. There are film MAF's that look like a thin piece of plastic. I have used sensor safe throttle body cleaner on the same MAF as shown in this video on my Impala and also on a film type MAF with no ill effects. Until someone comes up with more than "only use MAF cleaner" and speculations of what not using MAF cleaner can do I am going to continue to use throttle body cleaner. I think sea foam may have left a coating on the MAF wires b/c I believe one of the components in seafom is diesel fuel, I still use seafom in my gas tank once a year. Have used Seafoam to clean my intake have not used it on my MAF. I also have an oiled air filter (K&N) so I have to clean my MAF more often.
I had the same issue... it came on but no hesitation in the car and I thought maybe I destroyed my MAF... turns out that you can disconnect the battery for like 10 minutes and the light should go off... its just the sensor telling the computer that the car wasn't running right.
You never spray the sea foam before the maf sensor. Always after the maf or straight into the throttle body
Seafoam's worthless for anything. It's the usual Consumer Scam.
scotty thank you for making these videos. I've saved a lot of money thanks to your channel!
Thank you so much! I was having a hell of a time knowing whether or not I had found the right component!
Scotty, Can a bad MAF sensor cause an engine misfire ?
LAPirate Yep. So can a bad fuel pressure regulator!!!👌
What a sexy mechanic. I'm gonna listen just cuz he said to. (I just love people who are good at what they do!) On my way to Autozone to get my cleaner! :)
I luv U
-_-
Mary Alice Hukill yooooo
Sound like she want that meat dinner scotty
You can try that, but it could damage the more sensitive MAF sensor models.
mafs on those just flat wear out, I'd try a rebuilt one first, see that all the time on those old things.
"just get the neck lined up, and slide it in to the hole"
Thats what HE said lol
I love your videos Scotty but please wipe the car wax residue out of your Corvette Stingray emblem, it looks tacky!
not my vette, I fix em for customers, but I don't clean up
Scotty Kilmer Lol, I see, I am relieved now! I would never leave wax residue like that on a car, especially a vette! Good work
Scotty Kilmer not ya vette you say .. but to do a skid in it wow nice one
PÅŲŁ ĽĄWŔĔŅĆĘ ŘŐWĒ he probably had permission, the owner probably watches his videos too.
Scotty is the man and
I really appreciate a well produced video like this.
Got off my couch and cleaned my newer toy's MAF and throttle body and added a Econo Aid throttle body spacer. WOW, what a difference! Revin up!
After how much milage should we usually clean this MAF sensor.
maybe every 30 thousand miles or so
Miles please tell me according to the kilometer unit?
Nadir Waziri if you can't convert miles to kilometres you need to sell your car you're not mentally qualified to drive.
Christopher O'Grady shut the fuck up who are you to talk like this dah dammay zayaah talaqaah dah khor aghaa kuss dah ughaim dalaaallah.
who ask you to reply.
If you want your MAF sensor to last don't use K&N/Oil coated filters the oil over time collects on the MAF sensor and causes inaccurate readings.
Thanks for the info. I use these, but I will be changing today.
Thank you. When my check engine light came on, it worried me it could be a big deal. Now I know what has to be done. I had Advanco check it out for me. Mass air flow sensor was my issue. Thank you again your videos are so helpful.
THANK YOU SO MUCH AGAIN SCOTTY! YOU ARE GIVING GREAT ADVICES TO MANY PEOPLE!
CRC mass air flow cleaner, in the instructions it says "do not use on vehicles with a Karman-Vortex air flow sensor, eg- Toyota Supra turbos, Mitsubishis, and most Lexus vehicles."
Sure glad I read that can before spraying down the MAF sensor on my Mighty Max. That could have been a $300 dollar blunder. Be careful people, these videos sometimes leave out little details...
lol how many maf cleaning vids did u post this to?
deusexguy Several. And since then, contacted CNC to find out what's up. Their response was that their cleaner was designed for hot wire type MAF's. Never saw any of this mentioned in any video I watched. Problem?
Michael McCurley Although I don't have any of these cars that great to know :D And a bit shocking as to why there isn't any mention on it anywhere else.
ReaLzEdits I think this has to do with a potential liability situation that in this lawsuit happy society, I can't blame the companies for being extra cautious in. I contacted CRC about this situation. They basically replied that their product was designed for hot wire (or plate) type MAF's, anything else is on their own. They also replied that the producers of K-V type units should just replace the unit. Yeah, right... I've got the Email buried somewhere, I can dig it up if you need it. Anyway, my best "educated" guess is, if you've got one these K-V systems, which are now obsolete, but work pretty well, if it's just dusty, leave it alone, if it's gunked up, I would maybe try a zero residue electronic component cleaner, Radio Shack and or any nerd shop has it, and budget for a replacement unit. Just in case. Mine's ('91 mighty max) just dusty, so I just reinstalled it, gently, like a bomb disposal guy would work.
My can of CRC MAF cleaner says to NOT use on supercharged engines,also.
Thanks Scotty! I replaced mass air flow sensor and starts great, no hesitation, and better gas mileage.
By far the best car info videos on CZcams. This guy is a genius!

Scotty your videos are quality. Thanks a million times for the help and great work you put in the videos man.
lots of things can leak gasoline, but generally worn seals or fuel injectors on parts or connectors cause big leaks. try some UV leak dye in the gas tank then do my video tests "finding and fixing car oil leaks" to see how to find them.
GREAT INFO, U DA MAN SCOTTY
If it will run faster than that when driving, that's normal, computer doesn't allow over revving while sitting.But if it won't drive over that rpm, check the fuel pressure first to see if the pump is wearingout.
Thank you Mr Scotty! Cleaned the maf and throttle body on my 2014 Honda brio! It is really now as smooth as butter! U r toooo good!
+anuj mathur glad to hear it, thanks for the support!
try to find evap leaks first, as that can make the other lean codes trip too.
could be that, could also be other electronic problems like computer modules.Best to have a pro analyze it in depth with his dealer level scan tool.
At first I thought, "Not another one of those lame videos", but after watching I said, "I LIKE this dude!" Thanks for the great attitude!
Love how this guy has been making his videos the exact same way, because we all know they’re perfect
Thank you Mr Scotty, I refer to your videos for every project involving vehicles 🚗 that require love and tender attention. You are such a help for many Pepe’s like myself. You single handedly have help large amounts of pollution belched out of our tailpipes. 😅😅🙌🙌
Thanks Scotty! problem fix right on the spot under 20 minutes... this video saved me 60 box, I ought you one!
I’m a millennial who doesn’t know anything about cars, and I could follow every single thing he said. Well done!
yes and pray it's that and not broken computer circuits.
you can, but it may not be needed. I was there when the Jays won the series ages ago. Went to York U.
Great videos Scotty!!!
Once again you've helped me out. Thanks, Scotty!
This guy is a real hoot! Plus easy to follow. Great stuff!
from one mechanic to another.. your the man.
I love this guy, he's a damn good mechanic, but he's also very funny and entertaining. Good work Scotty.
Tried your tips in this video and in your other videos. My car runs like new. Thank you!
hook up a dealer level scanner and have it analyzed, they are very complex and only such a machine can pinpoint such a flaw. anything from a vacuum leak to fuel injection problems can cause that
maf can do that, but so can tons of other things, like weak fuel injectors or weak fuel pump. Have them pressure tested first.
always good to remove the battery cable when removing any fuel injection parts. Have the maf checked, it may be shorted out. But if part had a guarantee, take it back
Hi, I took the van to a shop yesterday, he put a computer on it, and no codes came up, and he did do a Pressure test on the fuel valve, and the gauge read 0 just barley any gas coming out of it, Anyway it was the fuel pump going out. I bought one yesterday, and had a mechanic fix it, and now it runs great. Thank you for all your help. I sure wish you lived here, I would take my vehicles to you. You have good videos, and are very helpful.
Great Video! Excellent editing! Thank You! I have a service van I will be doing soon. Well done!
many things can do that, first get a guy like me to hook up a dealer level scan tool and analyze the live data, you can see if the MAF or other sensors aren't working right quickly that way.
Awesome straight ahead no bs and simple to understand and Scott is cool to watch do his thing thanx Rob
Why can't I find amazing mechanic like you. thanks for all your videos they help alot
i love this dude so entertaining and simplifies the job for you.
Your tips are so useful, thanks a lot Scotty i love em!
Love your videos Scotty ...you're always a great big help... thanks brother :)
TYSM. Was driving long distance earlier today and vehicle stalled. This was extremely helpful!
good vid easy to understand do it yourself man!
Super helpful as always. Thanks!
Gotta love those chevy express maf sensor. I always have trouble mine
Thanks for explaining it quickly, but clearly.
Scotty,
thanks for an informative , no bs vid. got a mafs reading on my wifes car, tire shop was kindly offering to replace it for $250 !
will try the cleaner first and install after market if I must. nice vet. Bob
It's a tiny one on top of the air duct going to the engine right past the air filter.
I had my MAF replaced a few years ago (Kia Carnival 2.5l V6 2005).....the new MAF cost me $390 AUD just for the part!!! Wish I knew about this before! The CRC MAF Cleaner cost $18 from the local auto shop, ($27 if you don't shop around). Prices in Australia are sky high. Thanks for your informative video.Cheers!
