Thanks bro... that hissing noise when I open the cap is exactly what I have!! Problem solved thanks so much! NOBODY on the whole dam internet ever bothered to explain how air relates to the gas cap except you. 😂That was exactly the piece of information I needed to solve my Corolla engine light problem.
Wish I'd have seen this yesterday. Changed the fuel pump. Changed the MAF. Changed the valve cover. On daughter in laws 2016 chevy trax. Went to the back of the vehicle and heard a gurgling sound. Stuffed a paper towel in it and the engine lined right out. Thanks for your help sir
gg...ex wife called said her corolla is having problem starting..wont start sometimes....she took it to oreily's and it gave gas cap code..your explaination pretty much sums it it up..if fuel wont work it.s not going to start..makes sense....much respect and big thanks.
So that’s what that sound was. Yesterday I check my gas cap and it made that exact noise. I’m definitely gonna change the gas cap now! Thank you so much.
Willing my hero. Our town and country was throwing EGR codes, then GASCAP... I was about to venture down the path of the EGR system then I found you. Same vacuum when taking the cap off, new cap and no more codes. Thank you sir! 73 and God bless
Sweet! Thanks, Willie! Just bought a clean 2012 Mazda 3 and check engine light went on after filling the tank. I left the gas cap on the top of the pump. Ooops, shit happens
Omg I have a 2007 Pt Cruiser and if I tell you I've had problems, yes I have. Gas cap and check engine light is on. Going to change the cap and see what's up. Thanks for the info. 🙏🏽
Thank you, I am going out to buy a new gas cap asap! I will try that first. Dash is showing check gas cap. Check engine light is on. Was told my canister purge valve was bad, but going to try gas cap first.
Thankyou sir my check engine light came on this morning on my way into work just for the heck of it I tightened it up come to find out I didn't have it on as good as I should have thankyou again 🤘👊💪
Booty Leg Farnsworth is your cars name? More creative than what I call my 2005 Mercury Grand Marquis. I call it the Beast. And my 1964 Ford F250 is Kermit e frog. And my 1955 Cadillac is Tusk.
Can a bad gas cap cause jerking and bucking? I plan on getting my coils and spark plugs replaced to help out, but wanted to see if this may be causing it.
Very informative. My check engine light came on today and so far everything seems to point the gas cap. Mine makes that noise sometimes but not all the time. So I’m guessing that means my gas cap is still faulty and it is finally triggering the check engine light? I have a locking gas cap I’m going to take it off tomorrow and put the stock one back on and see what happens. do I have to take off the negative terminal and reset the check engine light or will it go off automatically once I change gas caps? Thanks for your help.
My gas cap stopped clicking about 2 months ago, didn't think much of it, it still felt like it tightened. Then a couple weeks later, my check engine light turned still on. So I bought a new gas cap, the NEW gas cap didn't click either. I tightened it as much as I could and went on my way. I don't notice any performance changes at all but my check engine light is still on. Any advice?
Common problem in saturn vue but it will keep doing it even after changing caps over and over,the only info i could find to fix it is a locking gas cap
My check fuel cap on my 02 mustang has been on for 4 days. After the 2 day my check engine light came on. I’m hoping if I replace the cap will that solve my issue.👍🏽👍🏽
My check engine light code said gas cap. Been on twice now, today I replaced the gas cap right after they cleared the code. Hopefully that fixed the problem. However I just had a fuel pump replaced two weeks ago. Since then has this problem started. Hopefully it was just the gas cap. Fingers crossed.thank you Sir fir the info.
Very informative video, thank you ! My check engine light came on with my 2006 Toyota Tundra truck. I do believe it is the gas cap but the code says PO333 which is supposedly the Knock Sensor 2. Circuit High Input (Bank 2) issue(s). Is it possible the loose gas cap could cause this particular code reading instead of the “loose cap “ code of another number ? I will buy a new cap today but I would please like to know the answer as you are a very knowledgeable mechanic ! Thank you
I owned a Lexus ES350 and had to change the knock sensors on it. On that engine it was best to replace both knock sensors and a knock sensor harness at the same time so that I would not have to go back in and repair second time. Toyota make good vehicles, that car had 230,000 miles and it ran smoother than any other vehicle i ever owned.
I had the same issue a year ago and I just seen some one on you tube post about a gas cap to risk it and I think I fixed my problem after mas flow sensor put on new another sensor that didn’t needed it does make ur car run like crap
Wuddup Willie. I have a 2005 toyota camry. My service engine light now remains on. Everytime I pull the fuel door release switch to open the fuel door the gas cap is loose. I turn it until it clicks several times and close the fuel door but when I pull the switch again right away and check the cap it be loose. Do you know if when the switch is pulled to open the fuel door does that automatically loosen the cap for convenience or could my gas cap be malfunctioning?
Hey I had my fuel cap light on for a day and now my check engine lights on but I tighten my cap and it has not stayed on will it go off did I ruin my engine
I own a 99 chevy express..my service engine light came on..when I fill the tank, the service engine soon light go's out..I have a lock gas cap..I click it 3 times or so. To make sure it's tight..I'm wondering if it's my evap system
My check engine light has been a pain for months paired with a “tighten gas cap” message. Jiffy told me a new gas cap should clear the engine message too after runnng a quick diagnostic for free after changing my oil. About to throw my new $18 cap on and see what happens!
@@Zach-nv4ul it cleared the engine light after replacing the gas cap! Big relief 😅 . I did have to drive around for a bit for it to reset and clear the messages though, within a day it was all clear.
@@Tenderkisses88 thanks Sis! I went to do inspection and guess what happened?! Check engine light, got my oil changed and I’m replacing the gas cap in the morning (wish me luck lol)
yup just happened again but this time i had to really spray cleaner and wipe it off to get the C E light to clear dosent happen often car is 12 years old 123900 miles on it
Thank you teaching and sharing and helping with this knowledge and wisdom Mr Willie, great video and tutorial, many much thanks and God Bless you always dear sir. ♥️✝️🫵🏻🫠👍🏻
Would suck to spend that $$ for it onky to be a gas cap! Luckily the code registered my cap and it’s not clicking anymore. Hopefully this solves my problem too!
Willy my car sounded strange today Later I was just going to take my trash to the dumpster Strange sound under the hood and then about 3 minutes the check engine light came on. I will check tomorrow to see if it’s my gas cap.
My exhaust keeps popping every time I get gas. It will move back and forth and pop out the exhaust and have a gas smell. I've changed the coils, plugs, vap canister, mafs.. now I'm wondering is it just the gas cap before I spend more money.
I have the same problem but the only thing is, even when I changed the gas cap. The check engine light was still on and I was sure to tighten it correctly. I took it a few mechanics and they would say it's the gas cap but weren't much help because the light will still show
Can that cause also a fuel smell inside the car? I have a 2011 malibu and about two weeks ago it started smelling fuel from the vents but also even if the car is parked, smell on the outside….. common issue would be a vacuum line or injectors, but being parked I don’t think that would be the problem and also is consumes more fuel than usual, and a massage just popped out in my dash “check gas cap”….. thanx in advance
I changed my gas cap in my 2006 Ford expedition and had engine light removed from a mechanic friend, but my light came back on after a week. I noticed it came back on when we had rain and winds. I'm not sure if that's a coincidence or not. But Could it be a leak somewhere else?
What about for those with a Ford that has a capless tank. Mine just opens up from the door and there is no cap its sealed until you insert the gas nozzle from gas station. But there is definitely a problem that is happening in this area.
Thanks bro... that hissing noise when I open the cap is exactly what I have!! Problem solved thanks so much!

Glad i could help 😃
I love my Corolla, but I thought the vacuum noise was expected so I never tried to fix it!
And how did you fix it
Dang…. You are just a likable guy Willie. Thx for the pro tip
@fairautorepair2787 but how you fix it?
Man!!!!!! This video saved $500+ …. I checked the gas cap and it did that vacuum hiss you spoke of. Smh… Car shop almost got me.
Awesome

Did not tighten the gas Cap correctly, the check engine kept turning on! Finally figured out the problem. Thank God!
Awesome!
what did u do bc my gas cao was off for a while until I noticed and fixed it but the engine light is still on
@@jimmybarreraa2804I believe a mechanic needs to reset something in the car so engine light will go off
Omg I have a 2007 Pt Cruiser and if I tell you I've had problems, yes I have. Gas cap and check engine light is on. Going to change the cap and see what's up. Thanks for the info. 🙏🏽
Thanks man! Same problems, sucking air noise when opening, check engine light on! Now I know what is wrong!
You make my day!!!

Thank you very much
Good guy Willy is, I pray he survived the Covid!
Thank you. That is the code that keeps coming up on my 2005 Mercury Grand Marquis LS.
I have a question so does your gas cap click? Because my cap doesn’t click at all.
I have a grand Marquis gs 2004

THANX
Thank you i just bought one Cap i hope it works
Thanks man, I appreciate the knowledge
Big thumbs up this answered my question 👍👍
Thank you for your time
Thank you for watching :)
thank you so much for your help!
Is the code for the gas cap the same as a code for an evap canister? I don’t wanna change the expensive evap canister for nothing..
Great information Willie. God bless you friend!
Thank you!
My truck does that same same sounds when I remove the gas cap maybe that's why the evaporative system hasn't cleared on the scanner

Thank you 🙏🏾
Thanks for the tip Willie
God bless you and have a peaceful and blessed morning
When air gets in the tank will it cause gas mileage low like poor gas mileage
If the car running good cooling level if fine no strange noises it just needs resting

What did it sound like?
Great video and straight to the points.
Thank you i wish you be here in kC i will take class from you😊
Great video cause I did not know about the valve in the gas cap
Very informative video
I’ve changed the plugs ran a little better my light is now always on and threw EGR codes I’ll be back this should be the fix
Thanks. I'll try it
H-Town in House!!! - Galleria Area!!!
Yep yep. H-town represent
But once the gas cap replaced will the check engine light go off? And will the smell of gas leave the car?
Thank you you saved my day
Thanks for the video.
Thanks buddy
My exhaust keeps popping every time I get gas. It will move back and forth and pop out the exhaust and have a gas smell. I've changed the coils, plugs, vap canister, mafs.. now I'm wondering is it just the gas cap before I spend more money.
Will the engine light turn right off or how do you clear it to see if it comes back on? Gas cap was off for a while.
Mine has never clicked this is a replacement. Spent over 1k 3 different mechanics for evap codes . Ordered a gas cap yesterday.
Very nicely explained
Thank you so much!
I’ve heard a hissing noise from a fuel cap when my dad pumped gas and air was getting out of the tank
thanks. My jetta 2015 gas cap seems has the same issue
I have the same problem but the only thing is, even when I changed the gas cap. The check engine light was still on and I was sure to tighten it correctly. I took it a few mechanics and they would say it's the gas cap but weren't much help because the light will still show
Ur issue fix?
If a gas cap will cause an engine light to turn on then what codes is it going to throw?
Thank you for the video
Thank you.
Thank you

Just filled up my gas tank and the check engine icon came up boom, ford edge limited awd 2011.
I just bought a lock gas cap. I was told these are not very good, by someone, Is this true?
Bruh! This saved me money!
No hissing noise at all and I’ve filled it to half full. Van isn’t giving me any problems other wise.
How long for thecheck engine light to go off when you replace the gas cap 😮
The seal on my cap was bad,changed the cap and reset the code P0447.....All good
I’m having the same problems what’s steps should I take after replacing the gas cap?
Capless fuel filler engine light 2018 Malibu
I changed my gas cap in my 2006 Ford expedition and had engine light removed from a mechanic friend, but my light came back on after a week. I noticed it came back on when we had rain and winds. I'm not sure if that's a coincidence or not. But Could it be a leak somewhere else?
My mom has a 2006 GMC Canyon SLT and I need to know how to reset the check engine light because of the gas cap
I have same problem with the engine light 😭 found out gas cap not tighten
Same here 🤦🏾♀️
I found hoses to the evap can next to my battery the ends were dry rotted out
What about for those with a Ford that has a capless tank. Mine just opens up from the door and there is no cap its sealed until you insert the gas nozzle from gas station. But there is definitely a problem that is happening in this area.
Good question. Any problem with the nozzle, the filler neck assembly will have to be replaced.
I bought a new gas cap same problem but don't like the gas cap I got from autozone maybe have to get another
