L?

[@carlosmayorca4642]

I would've never thought of checking for a vacuum leak that way. So useful, safe and without spending extra money!

[@garybaxley5437]

THAT GAL KNOWS HER STUFF,GREAT PRESENTATION!

[@worshipwhilewewait]

GET OUT!!!!!!!!!!!!!!!!!!!!!!! The vacuum/soapy water thing was BEYOND what I could ever think. Do it to the exhaust all the time to check for leaks but NEVER thought of doing it on the actual throttle body flow. WOW!!!!!!!!!!!!!! That was a MOM moment. This Lady explains things like atrue Mom. LOVE THIS LADY! Have seen soooooooooooo many over the yrs She'd done and am totally floored EVERY time. OH MAN I can't wait to try this!!!!

[@luiscarrasquillo8299]

She’s so good explaining in short version 👍🏻

[@benzcrazy]

I improved my gas mileage by getting a locking Gas cap . Sadly with the price of gas I think someone has been sneaking gas

[@ShadeIsLikely]

She’s a boss mechanic. I wish I lived closer to her…it’s hard to find good technicians where I live.

[@lynbenson1835]

The shop vac diagnosis is pretty awesome. Plus, the soapy water will leave the engine slightly cleaner after the test.

[@robsdeviceunknown]

Holy cow. What a great idea with the shopvac. I NEVER thought about this lol. Man that's awesome.

[@martinespinosa]

Sounds great! Any chance of blowing something up with too much pressure from the shop vac?

[@Z14kt12timandjes1]

Would it be safer to leave the air filter in place for this test, to ensure I'm not blowing debris from my vacuum cleaner into the intake of my vehicle? Thank you so much for sharing this excellent testing idea.

[@noahyates636]

I’ve been trying to find a small vacuum leak in my jeep for months, hopefully this idea will work.

[@mikejerrett7354]

The shopvac idea is a neat trick, never thought of that before.

[@ORagnar]

Finding a vacuum leak with a vacuum! Clever! 12/24/23, 4:39 p.m.

[@dawnrobbins5877]

Cool! I'm not comfortable spraying carb cleaner everywhere either.

[@g-style4466]

I definitely like watching the videos at 1A Auto

[@oconnorcm]

Sue, do I need to clean my Shop-Vac super well first to decrease the chances of blowing crud into the air intake?

[@pfsantos007]

Excellent video. I bet another way to find vacuum leaks this way would be to listen for them with a small tube.

[@elvzwoods]

Great video, way more comfortable with this method than the ether method.

[@fieldsofomagh]

Very good presentation by a competent lady.

[@maherahmed1977]

Thank you for your explanation My 2014 jeep grand Cherokee gave me a check engine codes P2096, P2098 recently can you help me and if you have a video on fixing grand Cherokee Best regards

[@oralwayne7273]

I will use this tomorrow the cigar I use didn’t find any leak

[@murphytoadster9864]

Smart truck with the vacuum. I'll admit I'm kinda a chauvinist pig but man she is the only one that had this awesome vacuum idea on KZbin. Thanks lady👍🏻

[@joseluissaldana5792]

You’re so good god bless you for sharing your knowledge I would like to see if you can Mae a video of a 2001 Toyota Sequoia suspension thank you.

[@JI77469]

Any issue spraying bubbly water while the car is running? Or is it just a "heat safety" in case you touch something hot?

[@Frostensen]

This might be a stupid question, but why can't you spray soapy water when the engine is running?

[@joshr8666]

Would a leaking valve cover gasket cause air / fuel mixtures issues?

[@ifixeditmyself1926]

Very helpful. I will be doing this today. 👌🏽

[@MarioSays713]

I have an electronic throttle body? How do I perform this test? My guess is I need a vacuum line after the throttle body?

[@guilhermeg345]

Sorry for the dumb question but couldn't that be too much pressure from the shop vac ?

[@deman601]

I love her accent! Great videos as always

[@matthewcanavan8275]

interesting start

[@Clamlifenc]

You are so good with explaining things, love your videos ❤❤❤❤

[@neilyakuza6595]

That is a cool technique. Thanks!

[@Jdmorris143]

Good video! I do appreciate the car though. I got that one for my daughter.

[@nedmilburn]

So a vacuum leak makes the cylinder(s) run with extra oxygen, then the o2 sensor picks this up and says "we need more gas" resulting in the cylinder(s) running with more gas than needed...? Then when the air fuel mixture is balanced it reports "it's fine... don't inject extra gas" so then the engine doesn't get extra gas trim, resulting in the cylinder(s) getting too much air because of the vacuum leak... etc etc etc... ??

[@GreyRockOne]

Thanks for all the great videos, I haven't watched in a while and the last time I did, it was Mike who hosted, is he still part of 1A Auto? Thanks

[@someone1089]

I believe you have to keep the throttle body open by putting a brick or a heavy object on the gas pedal for this test. There is a chance that you could create a new leak by pushing a brittle piece of gasket/o-ring or hose which you have to replace eventually any way. It's a good idea overall.

[@1AAuto]

+Some One Thanks for the feedback!

[@M21-w1y]

If you blow out the O-ring, brittle gasket or whatever then you have accomplished what you set out to do, find your vaccumm leak!!!

[@a.g.7727]

Thank you so much for all that info! Keep doing a good job!

[@kmipos]

Wonderful insight

[@nikkisweet6006]

I have a Nissan Primera p12, just got it back from paint job, the safety lights came on, I hearing a humming sound when engine is switch off, sounds like it's coming from fuse box, now it's switching off while I am driving

[@christleydacosta4747]

My good teacher🙏🏽enjoy watching

[@brentrideau144]

Very informative and entertaining!

[@akshaygaming1869]

Can we use rtv silicon grey on the old gaskit if new one is not available in market? Is rtv silicon on rubber bad?

[@burningsoul1365]

great stuff, i enjoy watching your informative videos.

[@RabeaHussain]

Doesn't a vacciume leak causes lean condition?

[@thehealer913]

Great idea with the shop vac! Thanks for the video!

[@Papawatata]

I thoroughly enjoyed the shop vac Technique very much because it is such an awesome way of finding vacuum leaks on my own and at my pace. I went out and bought me a very inexpensive vacuum hose to do this vacuum test, this way I know for certain the vacuum hose would be super clean on the inside and not blow any dust or debris into the intake manifold. I didn't see any vacuum leaks on vacuum hoses, etc. at bank 1 or bank 2 ! However, to my surprise I did find bubbles forming at coils on the heads . I found piston number 2, 3, 5, & 7 & I stopped checking at that point. So, the Million dollar Question . . . Is it normal to see bubbles forming here??? Could this be a sign of worn out pistons or rings, or something else, perhaps very serious??? Please advise!

[@webguy943]

can you also use a smoke machine and blow it in to find the leak?

[@genen.7370]

I only hear that sound when I turn my vehicle off would that be a vacuum leak or things just winding down?

[@skylerrutherford9870]

Her accent makes it all the more fun

[@tracy3812]

You’re a great teacher!

[@therealspixycat]

Why is the o2 sensor reading high (rich) when having an airleak? What is logic?

[@mohamadsadiq8937]

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.

[@squirrelcovers6340]

I got a 0442 code😂😂😂CHECK YOUR GAS CAP first, before they convince you to buy a part.

[@lindachapman6002]

I like your vids! You have great ideas that are safer.

[@1AAuto]

+Linda Chapman Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c

[@potterbat3995]

Couldn’t you just spray all the components and drive down the road and then just check for bubbles? Void the vacuum step?

[@brianrussell1565]

My life goes on sometimes of by itself

[@HectorSanchez-lp6ll]

Excellent video! Thanks

[@damygeebo]

[@leonardothefabulous3490]

Good job.

[@benzcrazy]

But all joking aside thanks for the great help and advice

[@ryantaube6546]

Very good idea 🎉

[@steveradanovich4962]

Chevrolet means vacuum leak in French.

[@Skyhors3]

? Must be fate, or Devine intervention? Aborting my winter trip to Arizona after 350 miles, because of a vacuum leak. Gotta go back home, in the north, to fix it. Thanks

[@kumars172]

but why everyone says vacuum leak makes engine lean?? now Im confused again

[@jeffersoncoker]

What about us that still have carbs... Older restored vehicles..

[@gerardkavanagh144]

Well presented.

[@joelrunyan1608]

Air leaks before any sensors don't matter...

[@mayken6661]

Excellent video !

[@josephfiumara9065]

Luv it ! Thank U!

[@franciscoroche183]

Thanks help a lot

[@DaveSomething]

my EGR vacuum diaphragm is leaking...

[@Asad-NBT]

Great video. I got a *P0174* code, which means air-fuel ratio is running lean. Will this video be applicable for that code as well.

[@wonderwalls3565]

That mean you have less air coming in. check if your air filter is clean or not.

[@BigChant88]

Thnx:)
