Rough Idle? Strong Gas Smell? Here's Your Possible Problem!--Easy Fix! 

Good video. I'm learning more on RU-vid than in my Automotive class.

4 years later thanks for the tip! I'm replacing at least something every 6 months on my 2001 focus but it's worth it!

trying to find the cause of bad fuel consumption but when you mentioned the strong gas smell that really makes me think this will be the problem thankyou,chris

There has been a gas smell that comes put through the vents (stronger with the heater on), rough cold start (very loud), and cuts off (every now and then) after cold start. Now, the gas smell turns into...like a peanut smell off and on. The dealership told me that, "The vents are not 'connected to the fuel line."😒 This is a brand new car...got it last month and was in the shop before. I was told, then, that they couldn't find anything "mechanically wrong" with it.

Wow I have this problem with my buick lacrosse. I've been complaining about thus since 2019 and nobody can give me an answer. Finally thank God I found your video. I'm going to tell my Mechanic. I really appreciate you posting this video. Thank you so much!

Thanks. Nice, concise informational video with lots of pictures. I am running lean but this is a great thing to keep in mind.

I got a 85 Chevy Caprice I got up and running for about a month, after it sat for a couple years. All was well until it started running real rough out of nowhere, so I parked it. Looked under the hood and noticed gas coming from the part mentioned in this vid. Hopefully a quick replacement will do the trick. Thanks for your time and info 💯

Thank you for the video! I was driving to work and noticed a few things similar to this or a clogged catalytic converter. Hoping to make it back to see a mechanic because this will definitely be outside of my limits when it comes to cars. But now I know what to tell the shop.

Thank you so much for this information. I appreciate your straight forward and helpful video. GOD BLESS you

i had mine replaced with a ac delco unit. took about 20 min to install. runs even better now.🏁

Thanks for this video my 1980 Cutlass supreme is having this problem l am going to check that out tomorrow you are a life saver

You’re a life saver bro. I been looking for the solution everywhere

Now this is one issue you pointed out but what I like about your video is you gave instructions on how to diagnosis the regulator. Thanks

The fuel rail may have something that looks like a pressure regulator, but it's actually a pulse damper to reduce pressure pulsation and fuel pump noise. The mechanical pressure regulator is part of the fuel pump module that includes the pump, a reservoir, the gauge sending unit and a fuel flter.

Perfect! I was trying to figure out what was wrong with my car for weeks. It has all the system you mentioned but i couldn't figure it out. Spend money on multiple parts and still had the same issue. I was just about to order a new hp fuel pump. But im about to check my regulator first. That just may be the issue. Thanks so much

same problem my 1996 Chevrolet impala. Thank you

That’s what I thought my problem was. I have a 86 Corvette. Never drove one before I bought it so I didn’t know how it was supposed to feel. But it was shaking at idle. Then one day it didn’t start correctly and it liked stalling a lot. I almost bought a new battery and a fuel filter because I listened to people who think they know a lot when they don’t 🤦‍♂️ I’m glad I watched this video tho thank you I almost wasted money

thanks wife's car is doing this and I have been looking for leaks, and pulling my hair out, lol. Really like the simple and explain it as you did. BIG THANK YOU.

Thanks brother, sounds like my 3vze has a similar problem. Thanks for your knowledge 👍

Hey thanks alot, that was an issue I was having and I will go get this looked at!

2006 gmc savana, 4.3l v6...been having issues with starting it, when she starts running she burns rich(black exhaust) for a bit and then levels out. I thought it was a vaccum issue but didn't find any when I looked. I checked a couple of sensors, relays, etc...all good. Fuel pressure regulator makes a lot of sense but I didn't even consider it, mainly due to not being a mechanic for the passed 20 years... but also because it's hard to think straight when working on a vehicule at -15° 🥶😄 🙏 Thanks for the help. Liked and subbed. 🍻 I'll check it next.

Omg... thank you for your clear info!,, it was right on

Thanks for the video. It was very informative 👍

Great vid thanks mate...what about if the strong gas smell is coming from tail pipe?

Your voice is soothing❣💯

Thanks man. My 1998 toyota corolla le will start get up too temp. It will idle for a bit normally then the rpm needle will start goin up and down then it'll get really low like 350 too 400 rpm almost making the engine stall. It actually stalled the other day. Now this is my daily I can't have it breaking down on me and I can't afford too bring it too a mechanic. You never know they'll probably just tell me it's something other than the actual problem

Very helpful thanks my wife's 04 GMC ENVOY had a strong gas smell inside vehicle and coming outside the driver side front fender after watching your video went out and popped the hood BINGO found the pressure regulator within about 30 seconds had my mechanic replace the next day it was leaking at top pretty bad could have caused a fire.....THANKS so much for info 😎

all right some use a way to fix it hell yes thank you right on i will be trying this at daylight on my truck

Very helpful that what i need hear, engine running rich 👍

Thank you.... this is exactly what's going on in my car.

great oration and coverage.

@Flashback502/ This is another real good automobile Video experience right here to get my Unknown thought's totally Wrapped all around in regards to a Current issue that i am experiencing right about now there Sir. "Thank's". 🖐️

That’s exactly what my 1993 Honda doing. Im bout 2 try it. I will let you know

You are The Man, man!!!

having str8 up gas smell on my passat took the engine cover off put my noise on that pressure unite smell ike hell ..Thanks brother from detroit

Thanks this help me!

Good thorough explanation

Problem solved with this video. Thank you.

I have a 2014 Buick LaCrosse. When stopping at a red light, I have experienced intermittent rough idling before it eventually levels out. I recently started noticing an intermittent gas smell inside the cabin. I don’t smell gas when I get out of the vehicle or when I pop the hood. Any ideas?

Chevrolet Malibu had this issue. Of course, it had others ... like dexcool, pressure regulator, MAS failure, random shutoff when going over train tracks.

My 2003 mustang gt blows smoke that smells like straight gas also I changed the fuel filter and the o2 sensor but it still does the same thing

These things were NOTORIOUS for leaking in the Toyota 4Runner and Avalons with V6. Not a cheap part either.

Hey thnx brother, I wish I new this way back in the day. I have a 97 Plymouth Voyager 3.3litre, what should it read on the tachometer? Thnx this video helped

Have a safe trip,on oil 3800., when it goes bad gas backs up the vacuum hose and fills up engine! Had one catch fire.took The intake off ,full of gas !!!

thank you very much this was very helpful

This was very helpful thank you!

Hi! 😊 So I have a problem and I beleive this may solve the problem. HOWEVER, I am not sure. Because I initially thought there was air in my gas line or whatever. Because I ran out of gas. So when I finally filled up, my 2002 chevy trailblazer was almost vibrating. It doesnt feel like chugging. But it sounds loud outside of the car. Sounds more rumbly/chuggy. Feels more like vibrating though. In my mind,, theres a difference. Lol. I did some research and I came to that conclusion only due to the fact my car was prob suckin on air for at least a second right?😂 I am sorry, I don't know a lot about cars, but I am learning. I just need help on this one. And your video was very helpful/well done. I just dont want to take this apart if I am looking in the wrong direction. I thought I smelled gas but it was not a straight clear gas smell. It almost smelled dirty...?idk. Like a tiny hint, almost of...exhaust? If anyone has gotten this far or even seen this comment, I will be very surprised. If anyone has any idea what I am talking about and is willing to help, I would be so thankful!

I know this is a old video but does this apply to bmws direct injection system as well I smell gas in the morning and I can’t get my mpg back above 30 no matter how careful I drive normally I’m closer to 35 mpg with no ethanol gas

Really good vid! Thanks for posting. Btw, you sound alot like snl's "The Lady's Man"! (Not a bad thing!)

Does this apply to when you have the fuel pressure regulator comes inside the fuel pump as in GDI cars? I have 2012 accent. Thanks for the video!

Could it also be a flooded charcoal canister? I overfilled my gas tank once. Now it smells like gasoline when I first start the car and it idles just a bit rougher than before. I dont see the fuel pressure regulator leaking any fuel.

Thank you!

Thank you for this video.

Thank you

Nicely done

05 Ford Taurus. Just before it got bad there was a squealing, kind like a belt was having some problem turning on a pulley. Car would die going slow or stopping for traffic, but start easily. Lost compression, gas smell building, running rough, with a sound like some of the vacuum hoses were off, lots of PUH...PUH...PUH from the passenger side hood, car has been a great one for it's age, but after this started, would only go at about 25-30 mph, with gas pedal floored. I can't afford a big mechanic bill, can't afford to buy another car (senior, fixed income, and yeah let's just say it, a woman.) but I need a car as I live six miles from anything. So, do you advize fixing or getting something else? Let me repeat, car starts EASILY, but won't run faster than 25-30 mph, with heavy gas smell. Please need advice.

Thanks dude love your voice

Great video saved me brother!

Got a 2002 Outback H6. Missing bad from cylinder 1 and 5. But has a bad exhaust smell. Running really rough.

Where do I locate the Fuel Pressure Regulators on a WV Beetle?

In addition to these symptoms, I also noticed a loss of coolant. Any thoughts?

Thanks man for sharing that is awesome 👌.

If this smell exist, will you fail smog testing? .....also would this cause you having less MPG?

What would make a 92 lumina take forever to crank but when it does it will crankback every time untill it sets for 10 minutes. Then when it cranks back when engine is warm you have to play with gas pedal to keep it running enough to open it up going down road to clear out. But when you finally get it to crank when it's cold it doesn't do that it runs perfect till you turn it off at a gas station for 10 minutes.

thank you 🙏🏾 brother i think 💭 you solved the problem with my 2005 ultimate edition grand marquis it burns gas like a mutha🤭🤭and when i turn the A/C on it smells like gas and it shake a lil’some time too I just got to find where that’s at and change it if that’s the problem but i strongly think it is

This is what help fix my car and i it was the regulator.

Thanks man, I'll check it out.

I own golf 2011 gdi bluemotion, it smells fuel inside cabin, the engine seem running hard and bluemotion stops working. When i turn of The car i can smell awful exhaust smell from engine and the fan is still running hard. What is the issue?

Oh, what should my needle read on the tachometer ?

I think you mayhave solved my problem

Good advice thanks

Thinking about replacing my FPR soon what’s the line you pulled from the top of it called?

Thanks papi

Awesome video thank you

Bra thank you for this!

My Mazda tribute 2002 doesn't have a fuel regulator.!?? So what else can it be?.

Does This cause the engine to misfire And have the check engine light going crazy?

Can this being bad cause fuel to come out the tailpipe? We have a 98 Expedition with the 5.4

I called the law and they fixed it

I just watched your video. My Dodge Dakota idles very rough when I'm warming it up in the morning and revs itself up (Very high) when it nearly dies. Lately when I drive it just a mile the engine cuts off when making a sharp turn, or just cuts off if I'm at a traffic light or stop sign. Also a few times there has been white smoke coming in the air vents that smells like exhaust. Could this also be the fuel pressure regulator? Thank you

Big help. Thank you! Subscribing, u were right on.

My van loses power when I’m in the middle of driving and the exhaust gets louder like backfiring and I smell a lot of gas. I changed fuel injectors, coil packs, spark plugs and plug wires, still has a misfire. It was showing misfire in cylinder 1 and 5 and I did what it said but it went straight back to what it originally was doing

hell yea dude thanks a bunch

Great video!

mine doesnt rough idle but strong gas smell. i checked the spark plugs and they are all clean so its not running rich, could it be the regulator made it run lean instead

You are a very good man. Thanks!

Thanks man.

I have an 05 corolla ce. Anyone know where to find the fuel pressure regulator? Some say it's at the end of the fuel rail where the injectors are and others say in where the fuel pump is. I'm getting a smell of gas when at say a stop sign or light. Trying to figure out wth it is. A few told me to check the fuel pressure regulator. Some said fuel lines. The lines all seem to be in good shape. Any help is greatly appreciated

Nice thank you🙏🙏🙏

Hey thank you for your video it fixed my 1990 ford bronco I was smelling gas when driving and jerking and bucking and stalling at red lights so I got home I saw your video so I went out pulled the hose off the regalater a d boom there it is gas coming out got a new one on she runs like new .

Thanks bro

Milkshake residue inside engine any suggestions to resolve.
