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

[@FunWithGuns]

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?

[@lawnmowermanTX]

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?

[@karlwilson9669]

No

[@RobertoCassetta]

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!!!!

[@teravolt6113]

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.

[@amazingsparckman]

Probably the best mechanic channel on youtube.

[@avquest01]

+Sparckman I would say this too. I have seen many and Scotty is really good.

[@Macsk8ing]

the best mechanic, others spew too much unnecesarry bullshit to act fancy

[@theinformer4265]

I personally like Chrisfix more but Scotty is second

[@jlpeoples1]

Chrisfix is my go to as well! Scotty is a good one too.

[@juandef4115]

Jonathan Peoples I watched Scotty first. I'd recruit them both for the UK top gear show.

[@THEH2OMAN]

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!

[@OzzyskylerTheGreat]

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.

[@danielchardeman]

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.

[@brucehunter8203]

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

[@skunknumerouno]

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!

@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.

[@scottykilmer]

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

[@scientist100]

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.

[@MerkinMuffly]

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.

[@forenamesurname4576]

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.

[@techbill2900]

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.

[@TriggeredGnome]

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.

[@OMRS1]

You never spray the sea foam before the maf sensor. Always after the maf or straight into the throttle body

[@chass5438]

Seafoam's worthless for anything. It's the usual Consumer Scam.

[@JaimeGarciaisnumberone]

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.

[@lapirate3408]

Scotty, Can a bad MAF sensor cause an engine misfire ?

[@pharaohtheblackgod3425]

LAPirate Yep. So can a bad fuel pressure regulator!!!👌

[@BeefGummybears]

I’m glad my buddy recommended this channel to me . Hes easy to understand and got charisma. Great video thank you Scotty !

[@blade75964]

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.

[@forenamesurname4576]

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.

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.

[@nadirwaziri5294]

After how much milage should we usually clean this MAF sensor.

maybe every 30 thousand miles or so

[@MrMccurley]

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...

[@joshuahutto]

lol how many maf cleaning vids did u post this to?

[@MrMccurley]

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?

[@ReaLzEdits]

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.

[@MrMccurley]

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.

[@jamesvandegraft3295]

My can of CRC MAF cleaner says to NOT use on supercharged engines,also.

[@scottykilmer]

yes, both of those will greatly reduce power, especially the maf sensor.If you like my car help, be sure to watch my live car talk show every saturday morning at 10 AM CST on google events.

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

[@mikef888au1]

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!

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.

[@steveclark1254]

First time I've come across you Scotty and I'll be back. Great to have a no nonsense help video

[@ThereIsKnowSpoon]

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!

[@scottykilmer]

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.

[@lucylee2338]

Hi Scotty, thank you so much for all your help, but today I took my 2012 platinum f150 ecboost in for a routine oil change at a Ford garage here in Lex. KY…before the guy brought it back to me he came into the waiting area and said that my MASS AIR FLOW SENSOR was dirty, and it would cost 225.00 to clean it, but I told him I would just have it done later because I thought that was a little high….he also advised me there was over 1100.00 worth of other things that need to be done, and gave me a list of them to look thru… it was almost 5:00 pm, and he said they quit at 6:00 pm, but they would go ahead and fix them if I wanted, and I said you mean you can do 1100.00 in repairs in less than a hour…and he said yes …wipers being one of them he said they needed to be replaced, and I just had new ones put on 3 days ago…plus after I got home they had said that they had rotated my tires which was included in the oil change, but one of my rims has a tiny nick in it, and it was still on the left front where it had been prior to the oil change …so anyway that just seemed a little high to clean that sensor, and things didn’t seem quite right with all the other prices so i’m waiting on the repairs, and I just wanted to get your opinion first anyway…I also had a heater actuator go out on the drivers side on my way to the oil change, but forgot to mention it to them until after my truck was finished with the oil change…plus I didn’t know what had even happened to it anyway just knew cold air was blowing out on driver side…even if I put the control on 90….can’t wait to hear the price for fixing that…just bothers me because it only has 43,000 miles on it…I bought it new, and have taken great care of it, but now it seems as if it’s falling apart…as always thank u so much.

[@jezedwards3858]

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

[@aqrealestateking]

Scotty you are the BEST!!

[@wg7644]

So in 2021 I bought a 2002 Chevy Silverado 1500 5.3l 4wd. For 3 winter seasons it has beat itself up when starting when the Temp is 45 degrees or colder. This truck is extremely clean. Was 19 years old with 105,000 miles when I bought it. When starting it would cough, shake, stall, pop whine you name it all coming from under the hood. So TODAY I finally cleaned the MAP because I was warming it up for 25 minutes to get it to run remotely smooth. So I cleaned it in EIGHT DEGREE weather. The engine was stone cold and it started went up to 1500 rpms and within a second or two down to 1000 rpms and sounded GREAT. So simple. It didn't look like it needed cleaning. They are small perforations and they must get a "film" of oil or something on them. BUY THE MASS AIR FLOW CLEANER little can is $5.00 SPRAY ALL OF IT ON BOTH SIDES AND LET DRY.

try to find evap leaks first, as that can make the other lean codes trip too.

[@scottykilmer]

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

[@scottykilmer]

mafs on those just flat wear out, I'd try a rebuilt one first, see that all the time on those old things.

[@scottykilmer]

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.

[@user-zt9bx5lh2d]

Still the best mechanic on youtube.

[@MitchC-vr8nw]

Kilmer is pretty inventive. He's up there with Chrisfix, but with more theater. Well done, Scotty!

[@scottykilmer]

generally, No. When they wear out, they need replacing as they normally break down electronically.

[@scottykilmer]

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.

[@scottykilmer]

maf can do that, but so can tons of other things, like weak fuel injectors or weak fuel pump. Have them pressure tested first.

[@alfredoramos1978]

Tried your tips in this video and in your other videos. My car runs like new. Thank you!

[@Natedogg1952]

Really saved a number on my check engine troubleshooting on a new to new corolla. Either was the MAF sensor or bad aftermarket gas cap. Cleaned the MAF sensor and check engine light went off 100 miles later.

[@debragoodloe1558]

continue... he did not check the engine, he just went by what I said. I been going to this mechanic for years and I trust him. I really love this car and can't afford to get another right now. This hesitation seems to be the only problem I am having. Thank you.

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.

Scotty your videos are quality. Thanks a million times for the help and great work you put in the videos man.

[@scottykilmer]

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.

I would replace the maf sensor if unplugging it makes no difference, it should make a radical difference.

You can try that, but it could damage the more sensitive MAF sensor models.
