My 2008 Scion XB was running extremely poor. 300,000 miles on it. Changed Ignition coils, Spark plugs and cleaned MAF sensor using rubbing alcohol. IT WORKED. One point to make. Disconnected the battery so the MAF and its computer etc... sync up after it all put back together. GOOD luck and GOD bless. JC
Thank you for this teaching. I had slow start took a few seconds and sometimes longer. Then it didn’t start at all, After changing oil it started but still slow. I checked this sensor and also put oil on o ring and tightened screws well. It’s starting quickly now. Hopefully remains like this. Thank you so much. From Northern Ireland.
USED MASS AIR FLOW CLEANER ON A 1999 MERCURY AND GUESS WHAT; NO HESITATION ON ACCELERATION . RUNS SMOOTH NOW& GOT PASSING GEAR BACK WITHOUT DYING ON ACCELERATION
Thank you so much!! Instructions were easy to follow...did this myself after watching the video. Removed the part to check it first, then used the MAF cleaner mentioned, and put the part back in.... no issues. Took my van for a test drive right after and now the stop/starts are so much smoother than they were prior. Cost was only $9 as I had to buy the MAF cleaner. :)
Mass airflow sensor is basically a very tiny electrical resistance. The way how is measuring the air, is pretty ingenious. Basically ECU sends electricity through that tiny wire. Depending on the quantity of air, the wire will cool down, or heat up, thus increasing or decreasing its resistance. Therefore you measure the resistance and you get the amount of air. Absolutely ingenious. Therefore everything that affect its resistance, even a single dust particle, will send wrong data to ECU and this will result in abnormal engine operation.
I am very skeptical when it comes to cheap fixes. I've, had two Toyota Camry's in the past, both being 6 Cylinder models. I'm very familiar with this acceleration issue as mine's did the same and other V6's I've test drove. Skeptical but willingly to give it a try, IT WORKED immediately! how something so small can make a huge problem. Thanks for sharing because I'm sure I would have paid a lot going to a auto shop. total out-of-pocket was $3 and change, best money I've spent and a long time
Note: Before cleaning the MAF sensor, please do replace your Dirty Air Filter to prevent the MAF sensor from getting dirty again. There's no point in cleaning a MAF sensor without changing an Air Filter.
..."No point cleaning your MAF without changing your air filter" cause it'll just get dirty again?...do u wipe your ass after taking a shit? Why? It's just gonna get shifty again! ..??
I changed the air filter some months ago n when this problem occurred, i wanted to check n I checked but it was sooo clean like brand new. Idk if i put it wrongly but it seems correctly. Idk why it didn’t get dirty.
Not done yet! That part that you sprayed is the temperature sensor, there are two resistors (for air flow detection) down inside the hollow tube that also need to be cleaned.

Thnx, how can the two resistors be cleaned? One only have to just spray it all over, or what?
Thanks Paul for sharing, you prove the the saying "there is no such thing as free lunch" wrong, for Christian we can have a free sharing. I am not a rich man that is why as much as possible I do my own fix if I can. Have a blessed Christmas Rick
Well, my Impala was barely trying to start and really sounded like it didn't want to be bothered. Well, I took ur advice and It Sprung to Life ! Wow! You were spot on and I sincerely want to thank you.👍
Thanks for the video. My Corrola has 219000 miles on it and yesterday it would start but would not stay running unless I kept my foot on the accelerater. A 9 dollar can of mass airflow cleaner and following the steps of your video fixed the problem. Bless You.😊😁🇺🇸
I have the sme sensor in my Toyota at idl it was reving up and down i cleaned it and it works perfect now . Use a plenty of the cleanor for best results
I usually let mine dry for a half hour before reinstalling. I also spray down inside the housing. I think there is another wire in there. 2006 Toyota Matrix 4WD. You can also use an app like Torque with a Bluetooth OBD2 reader (mine has an on/off switch-I just leave it plugged in and off unless I'm using it) to make a note of airflow at idle after cleaning sensor. This will help you determine when to clean sensor.
Just had this problem on my Escape V6, fixed it by changing 2 faulty ignition coils and all the 6 spark plugs, on top of that they also cleaned the MAF sensor and flushed out the air intake system. Now the car runs very well. Thanks for the video Saul :)
My check engine light came on in April. I had my spark plugs and ignition coils changed, but the car still wasn’t accelerating smoothly like it was before I had the work done. I took it back and the spark plug wires were changed. Since then, I’ve had my wheels aligned and my 50K mile maintenance service which included an oil change, break fluid, and transmission fluid. Car still isn’t accelerating smoothly. I have taken the car into different shops AT LEAST five times and they’re telling me nothings wrong. I’m so tired.
@@kenantv7487 Donno, the problem kept coming back, I ended up selling the damn thing for 500 bucks to a Ford mechanic. Even now he struggles to keep it roadworthy. Buy a Japanese car.
I have a 2010 honda stream rsz 1.8 liter engine cars run good on flat but when going over hill it just dies down about to shut off no engine check light what might be my problem
No too long ago my car just started stalling out on take off, would have to hold the gas down a bit at stop lights to keep it goin. Pulled the MAF sensor and inside was a tiny spider that was dead hanging on one of the wires. Got it off and car ran like new again.
What An Awesome User Friendly Video . I Wtched Ur Video Tried It & It Worked , The Engine Hesitation Gone .My Beloved Runx 2zz Now Taking Off Like A Bat Out Of Hell 😊 Thanls & Ever Thanks !!!
I owe you a huge debt of gratitude. To think I was going to spend $300 on a Speed Booster. My 2015 Lancer fet totally sluggish despite synthetic oil and great gas. I cleaned my sensor and my pick up totally increased. Thank you very much for your video!
Mass Airflow Sensor cleaner is the same stuff as CRC Electronics cleaner. They both evaporate quickly and leave behind no residues, without being too harsh on sensors.
If you’ve ever owned a Nissan Maxima that mass air flow cleaner was your best friend . My old 02 6 speed would stall out at the light every time , until it was cleaned
Did this but had to get a special short screwdriver and someone to pull the plug out. Thank you it worked got the warning lights off but then went on again. I guess I'll have to wait 50 miles and hope there is no other issue.
My 87 runs really good but it has a constant intermittent hesitation as if it hiccups, has good pick up speed and with air on, sitting at a light sometimes it will stall, but starts right back up, I did all the cleaning stuff like you all say on here, and can't wait to see if it works, but this car has issues, one thing quits working and you fix it then another thing quits ?? I get a lot of compliments,(nice car) but again its black and new convertible black top, and new tires its a nice driving car till this problem, And I've been working on cars with my father since I was 8 yrs old and I am 60, just want to drive and enjoy life.
actually the "wires" dont do much, they simply increase in temperature as a means to give the PCM a reference point so it can notice the differential relationship between the "hot" wires and the cooler intake air to procure the algorythms needed to adjust fuel/air proportions as per specs whicj are stored in the PCM....I like yur vids but be sure and inform your followers that the neg battery terminal needs to be removed before dealing with ANY sensor
my 2013 model Hundai Tucson SUV has started to develope this hesitation at the early morning hours, it does not have enough power at the start of the engine and when I press the gas pedal too much during that stage, I hear some knocking at the exhaust. Also, it does not have the power like it used to have when climbing elevated road. surely appreciate your response. thank you sir...
2001 mercedes C180 just got fixed thanks to your video. I did use brake cleaner because that is all i had at home. but it works better now. I did not clean it thoroughly though so I still have occasional sputtering. planning to just replace the MAF. I was worried that the brake cleaner would damage the MAF but it did not
proclaimliberty2000 didn't the can say not to use it on Toyota's? I know because I thought of using this once on my 06 v8 Tundra but I got discouraged as soon as I read "DO NOT USE ON LEXUS OR TOYOTA ENGINE'S" I use to work at AutoZone n a mechanic gave me advice n said to just replace it with an oem one from Toyota so how's it holding up for ya?
Hi but i have same problem idles goes up & down Mazda Demio petrol 1985 model fuel injected is the car u are working on same like mine? thanks great video
Thanks for the video. And I'm not a pro but what you point out and spray with the cleaner looks to me quite a lot like a ptc or something for temperature sensing. The really thin wire that measures the oxygen flow should be in that bigger window. It still got a good amount of the cleaner but yeah just saying. Otherwise keep it up :)
I like to thank you for your easy and understandable explanation. Just Saturday finished at work to go back home and the middle of the way which is about 1 mile, I was waiting for the green light at the stop light and when I gave gas to my Car it hesitate it so bad I thought the engine is going to go off but it didn't, I continue to go forward but I noticed it was running rough like never before, I was afraid that my Car would stall and proceed to get out of the way because I got a lot of cars behind me, I shut it off and waited for a few minutes then turned on and made it home safely today I needed to go to the store and you did the same thing, I like to thank you for posting this, tomorrow morning I will do a cleaning to that sensor but I don't have that spray, do they sell it in any auto parts store? Thanks, JD
Oh man. It just happened to me couple days ago when i came to red lights. I stayed there for 20 min n cars were coming n waiting behind me while hazardous lights were on, then move on next line. I was talking to AAA, but after waiting for 20 min there, i turned it on n i drove. I didn’t know what happened but i also have the same problem that my car struggles to accelerate, maybe this caused that problem as well. Tomorrow will try this
@@jorgedominguez1957 just came here to tell u said: man, u’r not gonna believe but it just happened again. I was driving n in the middle of the road, my car stopped again. Since i got experienced couple days ago it happened, so this time i behaved quickly n tried to turn the car on immediately, luckily, it worked again coz it was one way n holiday week so already bad traffic n i d not want to cause extra traffic lol. Btw, i just bought mass air flow but i also asked the mechanic n he said if u don’t have any lights on, don’t do anything by urself coz it’s new car so just take to body shop n asked them to look at it , otherwise, if u do smt wrong, they’ll say we didn’t do it. (My car had body shop repair for bumper n they changed intercooler, but I already told them this issue n they changed it again but still the same issue) going to try mass air flow.
oh. my. God... Sir, U may have just saved my Stang & me a whole crapload of money & further issues... MAF Sensor... nvr knew of it. changed so many other Intake platforms, but NVR touched ths one... let U know how it went later...
I can't find my air flow sensor sir ..it's missing... I think my macanic missed while installing cold air intake. I am getting problem while accelerate car not running how supposed to run
Darel Dias bro my mustang 2015 v6 has same issue when u turn on the speed then @ speed 80 my car misses for a second then it goes up 80 speed how to diagnose it I have cold air intake as well
My Ford Focus MK1 2001 doesn't seem to have one?? It has the hard hose part just after the air box, but there's nothing in it, nothing it the pipe either. It goes straight to the throttle body with the throttle positioning sensor etc.. How does the car know the air flow?
I haven’t drove my car for a month and the mechanic’s told me it might be a engine problem or something with the fuel system , so I checked my fuse box and it was a bad etcs fuse #10 and my car is good now.
Man I hope this is the issue just bought a 2014 Silverado and I love it but I accelerate and It jerks im gonna do this before I take it to the dealer hope it works out man ty for the vid man
Did that it helped for 100 miles then back to the same trouble as before. For $ 35 replace the sensor. Should take care of the problum if not the throttle body needs to be cleaned or replaced.
How can we actually know that this is the actual problem? Coz my car also struggles to accelerate when i press the gas or brake. It had body shop service n they changed the intercooler too. After I realized the problem, i went back n told them n they said it might be intercooler coz thats the only thing they touched when they changed the bumper so they changed the intercooler the second time with factory product but i still face the issue. Any suggestion?
I know exactly what he's talking about I got a 2015 Dodge Grand Caravan that has this issue. It basically has trouble catching up to itself so is a tad jerky off the start. I feel like if I were to clean that censer it would no longer have that problem.
I’m going to try this tonight. I have a 2003 Ford Focus and I keep getting engine misfires (P0302) and often rough on acceleration from a stop. One time the car just decelerated on highway (only once - checked transmission and it’s fine). Plugs, wires, and cylinders all good. If this doesn’t work - what should I try next? So sorry to ask the question, but I’m on a tight budget and am doing it myself.
This does not sound like a mass air flow sensor problem. P0302 trouble code is an indication that cylinder #2 is misfiring and is not getting the necessary spark to its spark plug. It's very possible spark plug #2 has a loose electrical connection on the spark plug itself or a failing ignition coil which is very easy to replace. Let me know what happens.
proclaimliberty2000 should I test for ignition coil problems then? This problem has been here for so long and getting told to just replace spark plugs when I already did by a mechanic just shot me down. Regardless I might clean the MAF anyways for good measure. Thanks for your response!
hi friend, you said that it would take 50 miles of driving for the check engine light to turn off. What if the check engine light wasn't turned on to begin with and I just wanted to clean the maf sensor? would the check engine light turn on after cleaning? thank you
As long as the key is not in the ignition it should not turn on the check engine light when you disconnect the MAF to clean it. th-cam.com/video/YnckaCCJEEk/w-d-xo.html
Hello, I have a problem with my 2003 Mercury sable, first of all it does a small series of things that I can’t for the life of me figure out the problem, After my car warms up a little and you happen to be at a stop light or at a hill and as soon as you press the gas peddle it jerks before it goes, like kinda a delay, here lately I noticed when I’m going down the highway with cruise control set at 65 going on level road it’ll ever so slightly slow down and speed up (like go to 63 and back to 65), and sometimes when you stop and put it in park it’ll start revving upwards of 2000-2500 rpms and stay there. No engine light has gone off except every now and then and I read the code it says “manufacture control” but that hasn’t happened in a couple months, also sometimes in park when it’s not revving up it’ll start revving up and down constantly and the car sometimes dies on its own, I went into the store one time and left my car running for the ac and when I came back out my car was dead and it ran the battery down since the accessories kept running, can someone please help me solve this problem!!!! The problems are starting to happen more often, please help me figure it out!! Thanks!
It may be some kind of simple sensor such as an oxygen sensor, MAF sensor, TPS sensor or other sensor. Is your air filter clean? It's possible you could have a throttle body sticking which you need to clean if it's dirty. Not having a check engine light on makes it more difficult to diagnose. You may need to take it to a good trust worthy mechanic. th-cam.com/video/cOAYWVBfuek/w-d-xo.html
I have a question. I drive a Lexus & went over a dip & now when I drive above 65 it smells like burn oil but has no leaks. Please help??? Thanks for the video by the way
My moms 2005 Nissan Murano is running a u3fff code and apparently that’s for Nissan dealers only, but the car is hesitating and kind of shaking. She’s already changed the coils and it was running fine but now it’s reading that code and the dealership told her it cost $120 just to get the code read..
My gas doesn’t feel smooth when pressing the pedal and I’ve taken it to multiple auto repair shops multiple times regarding this issue. They keep telling me nothings wrong. Does VW Jetta’s have this part?
I have a problem. Not sure if it falls under the jurisdiction of your video. If I stop at some stop sign, and then I have to enter the road and accelerate, there is a couple of seconds during which I get no acceleration. I can hear the engine roaring, but for couple of seconds, no acceleration. But then the rest of the drive is smooth. I have Nissan altima 2009. Does the solution in your video is exactly related to my problem.??
Since getting my engine code read and it coming back as the MAF sensor I called another mechanic shop and asked about getting it cleaned and they said it would be $300 because the MAF sensor for Nissan uses a special type of chemical and cleaning it is not an option. After he told me that I started looking up videos on it and I see plenty of videos like yours with people cleaning it and they made no mention of any sort of special chemical being involved with the MAF sensor to where it prevents it from being cleaned. I’m gonna go out and buy a can of the cleaner and a screwdriver and clean it myself to save myself from $300
I live in California and since I’m moving and planning on driving my car to Wyoming I want to see if I can try to fix with cleaning it first. So I’m gonna buy the spray first and hopefully that would do the trick because I don’t know if driving from California to Wyoming would be a bad thing with the MAF sensor issue
Hello I have a question. This happens with every automatic car I buy. I accidentally switch gears from park to drive and let off the break too quickly. After a while of doing this on accident than the car doesn't switch gears smooothly while driving. It jerks forward and. Did I mess up the transmission and is this a big fix? Please help.
I tested my maf sensor by starting my car and pulling out the maf sensor plug and the car stopped. Doesnt that mean the maf sensor is working properly. Im having power loss and lurching and hesitation when i accelerate and its getting very frustrating.
Hi, my 2007 audi a4 b7 has very weak rev at idle. I stepped on the gas and the rpm just slowly goes up. Before it revs up nice and strong. Any help would be greatly appreciated. Thanks
I have a 2013 honda cr-v it hesitates about the third crank it starts then my check engine light is on and other lights I just put a alternated on today doing what's in your video should that fix the problem or should I look into the full pump it doesn't bog down or skip going up a hill or nothing but when I run the car a bit I shut it off then when I get back in it it starts right up and the check engine light is off so could the mass air flow be the problem?
My 96 Jeep Cherokee has a problem I can't diagnose. The symptoms are similar to a bad/ dirty Mass Airflow Sensor and Throttle Position Sensor, but the symptoms don't fit either exactly. It happens only while driving, not while idling. The engine will suddenly lose RPM as if it want to die for a couple seconds then will go back up to normal, then down and up repeatedly for a couple minutes then will clear up and run fine for a while. It also seems to "pop" lightly like it wants to back fire but can't. Would you consider this a problem with the MAS or TPS or could it be something else? Thank you. P.S. I've tried changing fuel to a higher grade and used fuel injector cleaner.
I used the spray to clean the MAF, things have become better for some time but after that the same problem started again (car little hesitates and shakes when starting).

Hi guys, I used brake cleaner for mass air flow sensor and it did the job just fine. The engine is more responsive now.
mistake and wrong. the brake cleaner leaves a residue. MAFS cleaner is the same as electronics cleaner... NO residue. SEE?

indeed a simple fix for a big problem...and it works too.......

I did not clean it thoroughly though so I still have occasional sputtering. planning to just replace the MAF. I was worried that the brake cleaner would damage the MAF but it did not
I'm sure once you replace it your performance will improve dramatically.
proclaimliberty2000 didn't the can say not to use it on Toyota's? I know because I thought of using this once on my 06 v8 Tundra but I got discouraged as soon as I read "DO NOT USE ON LEXUS OR TOYOTA ENGINE'S" I use to work at AutoZone n a mechanic gave me advice n said to just replace it with an oem one from Toyota so how's it holding up for ya?
My can doesn't say that and there have been no problems.
I bought a new one; i also replaced the fuel pump and it's running lovely now
proclaimliberty2000 what car is this you are working on ?????
Very very informative and nice video
Thanks for special information god bless you sir
I would of loved seeing the issue before and after
Hi but i have same problem idles goes up & down Mazda Demio petrol 1985 model fuel injected is the car u are working on same like mine? thanks great video
Thanks.
DO THEY SELL A BIGGER CAN i may need more than ten gallons!
I will have to try this since my 1992 Honda accord has been getting worse with stalling when I stop and severe surging on acceleration.
It sounds like you also need to perform this. th-cam.com/video/cOAYWVBfuek/w-d-xo.html
Great video, thanks!
Thanks for the video.
And I'm not a pro but what you point out and spray with the cleaner looks to me quite a lot like a ptc or something for temperature sensing. The really thin wire that measures the oxygen flow should be in that bigger window.
It still got a good amount of the cleaner but yeah just saying.
Otherwise keep it up :)
We appreciate this video💌
SWEET! Gonna try this first... automatic 2012 Camry, sluggish at 2nd gear. So easy, hope it's a fix, thank you!!
Thanks for this video sir,Berry good

I like to thank you for your easy and understandable explanation.
Just Saturday finished at work to go back home and the middle of the way which is about 1 mile, I was waiting for the green light at the stop light and when I gave gas to my Car it hesitate it so bad I thought the engine is going to go off but it didn't, I continue to go forward but I noticed it was running rough like never before, I was afraid that my Car would stall and proceed to get out of the way because I got a lot of cars behind me, I shut it off and waited for a few minutes then turned on and made it home safely today I needed to go to the store and you did the same thing, I like to thank you for posting this, tomorrow morning I will do a cleaning to that sensor but I don't have that spray, do they sell it in any auto parts store? Thanks, JD
Oh man. It just happened to me couple days ago when i came to red lights. I stayed there for 20 min n cars were coming n waiting behind me while hazardous lights were on, then move on next line. I was talking to AAA, but after waiting for 20 min there, i turned it on n i drove. I didn’t know what happened but i also have the same problem that my car struggles to accelerate, maybe this caused that problem as well. Tomorrow will try this
@@kenantv7487 cool man, try it
@@jorgedominguez1957 just came here to tell u said: man, u’r not gonna believe but it just happened again. I was driving n in the middle of the road, my car stopped again. Since i got experienced couple days ago it happened, so this time i behaved quickly n tried to turn the car on immediately, luckily, it worked again coz it was one way n holiday week so already bad traffic n i d not want to cause extra traffic lol. Btw, i just bought mass air flow but i also asked the mechanic n he said if u don’t have any lights on, don’t do anything by urself coz it’s new car so just take to body shop n asked them to look at it , otherwise, if u do smt wrong, they’ll say we didn’t do it. (My car had body shop repair for bumper n they changed intercooler, but I already told them this issue n they changed it again but still the same issue) going to try mass air flow.
@@kenantv7487did it get fixed?
Thanks paul❤
this is why new technology fails I like classics better
true
@PGm issa maybe but the issues were much cheaper and easier to fix
Like my instructor said carburetors are for old people who wont die lol but they still easier to maintain
Helped a lot thank you so much
oh. my. God... Sir, U may have just saved my Stang & me a whole crapload of money & further issues... MAF Sensor... nvr knew of it. changed so many other Intake platforms, but NVR touched ths one... let U know how it went later...
Hope it fixes the problem.
Mine was real bad i had to soak it in cemen overnight and then had to wory about geting the 02 senter pregnet
Well did that shit fix it??
I want to see how it works after you cleaned and installed.
I can't find my air flow sensor sir ..it's missing... I think my macanic missed while installing cold air intake.
I am getting problem while accelerate car not running how supposed to run
Darel Dias bro my mustang 2015 v6 has same issue when u turn on the speed then @ speed 80 my car misses for a second then it goes up 80 speed how to diagnose it I have cold air intake as well
not every car has one. some just have a MAP sensor
Thanks for ur video sir, is helpful this what I need.
My Ford Focus MK1 2001 doesn't seem to have one?? It has the hard hose part just after the air box, but there's nothing in it, nothing it the pipe either. It goes straight to the throttle body with the throttle positioning sensor etc.. How does the car know the air flow?
How we sopose to know that's the fix? How was runing that engine before the MAF sensor is cleaned?
Drive and find out? It’s a tutorial of a possible fix. “Possible”
Are you in Florida. The Driveway i could tell.
I haven’t drove my car for a month and the mechanic’s told me it might be a engine problem or something with the fuel system , so I checked my fuse box and it was a bad etcs fuse #10 and my car is good now.
I'm going to give this a try, thanks!
Man I hope this is the issue just bought a 2014 Silverado and I love it but I accelerate and It jerks im gonna do this before I take it to the dealer hope it works out man ty for the vid man
Update?
Did that it helped for 100 miles then back to the same trouble as before. For $ 35 replace the sensor. Should take care of the problum if not the throttle body needs to be cleaned or replaced.
How can we actually know that this is the actual problem? Coz my car also struggles to accelerate when i press the gas or brake. It had body shop service n they changed the intercooler too. After I realized the problem, i went back n told them n they said it might be intercooler coz thats the only thing they touched when they changed the bumper so they changed the intercooler the second time with factory product but i still face the issue. Any suggestion?
Would any quick drying cleaning product work???
Neftali Garcia Not if it leaves residue on the wires. That’s why I only use mass air flow sensor cleaner.
Goodmorning,
My engine hesitate anD i noticed water dipping from my exhaust, what would be the possible cause of this. Thank you sir
This was very helpful for my Maruti Suzuki swift dzire as maf sensor was same!
Sir,I owe wagonr amt ,where is maf/map in there,please help
Do you have to undo the battery terminal first before you do this ?
Nop
As long as the starter switch is off or remove the key it should be ok.
I know exactly what he's talking about I got a 2015 Dodge Grand Caravan that has this issue. It basically has trouble catching up to itself so is a tad jerky off the start. I feel like if I were to clean that censer it would no longer have that problem.
I’m going to try this tonight. I have a 2003 Ford Focus and I keep getting engine misfires (P0302) and often rough on acceleration from a stop. One time the car just decelerated on highway (only once - checked transmission and it’s fine). Plugs, wires, and cylinders all good. If this doesn’t work - what should I try next? So sorry to ask the question, but I’m on a tight budget and am doing it myself.
This does not sound like a mass air flow sensor problem. P0302 trouble code is an indication that cylinder #2 is misfiring and is not getting the necessary spark to its spark plug. It's very possible spark plug #2 has a loose electrical connection on the spark plug itself or a failing ignition coil which is very easy to replace. Let me know what happens.
proclaimliberty2000 should I test for ignition coil problems then? This problem has been here for so long and getting told to just replace spark plugs when I already did by a mechanic just shot me down. Regardless I might clean the MAF anyways for good measure. Thanks for your response!
Brenna Paulson It’s very possible that replacing the ignition coil will fix it.
hi friend, you said that it would take 50 miles of driving for the check engine light to turn off. What if the check engine light wasn't turned on to begin with and I just wanted to clean the maf sensor? would the check engine light turn on after cleaning? thank you
As long as the key is not in the ignition it should not turn on the check engine light when you disconnect the MAF to clean it. th-cam.com/video/YnckaCCJEEk/w-d-xo.html
Hello, I have a problem with my 2003 Mercury sable, first of all it does a small series of things that I can’t for the life of me figure out the problem,
After my car warms up a little and you happen to be at a stop light or at a hill and as soon as you press the gas peddle it jerks before it goes, like kinda a delay, here lately I noticed when I’m going down the highway with cruise control set at 65 going on level road it’ll ever so slightly slow down and speed up (like go to 63 and back to 65), and sometimes when you stop and put it in park it’ll start revving upwards of 2000-2500 rpms and stay there.
No engine light has gone off except every now and then and I read the code it says “manufacture control” but that hasn’t happened in a couple months, also sometimes in park when it’s not revving up it’ll start revving up and down constantly and the car sometimes dies on its own, I went into the store one time and left my car running for the ac and when I came back out my car was dead and it ran the battery down since the accessories kept running, can someone please help me solve this problem!!!! The problems are starting to happen more often, please help me figure it out!! Thanks!
It may be some kind of simple sensor such as an oxygen sensor, MAF sensor, TPS sensor or other sensor. Is your air filter clean? It's possible you could have a throttle body sticking which you need to clean if it's dirty. Not having a check engine light on makes it more difficult to diagnose. You may need to take it to a good trust worthy mechanic. th-cam.com/video/cOAYWVBfuek/w-d-xo.html
I have a question. I drive a Lexus & went over a dip & now when I drive above 65 it smells like burn oil but has no leaks. Please help??? Thanks for the video by the way
Brandin Sanchez Are your drive belts good and tight?
Thank you for this video
My moms 2005 Nissan Murano is running a u3fff code and apparently that’s for Nissan dealers only, but the car is hesitating and kind of shaking. She’s already changed the coils and it was running fine but now it’s reading that code and the dealership told her it cost $120 just to get the code read..
Doomzyy take the vehicle to an auto parts store to have it checked with a diagnostic scanner which they will normally do for free.
proclaimliberty2000 we did, the scanner came up with u3fff which is apparently a code only a Nissan shop/dealer can read.
Clean mass air flow sensor. But also check air filter.
I did all that too, and new air filter but its killing me so bad I want to sell it.
Matthew Simonds if it's not idling right also check to make sure no coolant is running down into the spark plug holes 😒
My gas doesn’t feel smooth when pressing the pedal and I’ve taken it to multiple auto repair shops multiple times regarding this issue. They keep telling me nothings wrong. Does VW Jetta’s have this part?
I have a problem. Not sure if it falls under the jurisdiction of your video. If I stop at some stop sign, and then I have to enter the road and accelerate, there is a couple of seconds during which I get no acceleration. I can hear the engine roaring, but for couple of seconds, no acceleration. But then the rest of the drive is smooth. I have Nissan altima 2009. Does the solution in your video is exactly related to my problem.??
Nabeel Ahmed sounds more like transmission
Thanks buddy you made my day.
Since getting my engine code read and it coming back as the MAF sensor I called another mechanic shop and asked about getting it cleaned and they said it would be $300 because the MAF sensor for Nissan uses a special type of chemical and cleaning it is not an option. After he told me that I started looking up videos on it and I see plenty of videos like yours with people cleaning it and they made no mention of any sort of special chemical being involved with the MAF sensor to where it prevents it from being cleaned. I’m gonna go out and buy a can of the cleaner and a screwdriver and clean it myself to save myself from $300
Babs Yeah. they are absolutely trying to rip you off. Happens unknowingly to people every day.
If you end up having to buy a new one check Amazon. I just checked the price on one and they were cheaper than Ebay. I have always used Denso brand.
I live in California and since I’m moving and planning on driving my car to Wyoming I want to see if I can try to fix with cleaning it first. So I’m gonna buy the spray first and hopefully that would do the trick because I don’t know if driving from California to Wyoming would be a bad thing with the MAF sensor issue
@@jurnee-y That sounds like a great plan. Are you moving to Wyoming?
Yes
Hello I have a question. This happens with every automatic car I buy. I accidentally switch gears from park to drive and let off the break too quickly. After a while of doing this on accident than the car doesn't switch gears smooothly while driving. It jerks forward and. Did I mess up the transmission and is this a big fix? Please help.
motor mount?
2018 Ford eco sport perking during acceleration after 60/70mph and already had the engine replaced because of the oil pump and engine failure.
I tested my maf sensor by starting my car and pulling out the maf sensor plug and the car stopped. Doesnt that mean the maf sensor is working properly. Im having power loss and lurching and hesitation when i accelerate and its getting very frustrating.
Had a issue with my Neon where it wouldn't accelerate past 2300 rpms. I fixed it with a new cam shaft position sensor.
Hi, my 2007 audi a4 b7 has very weak rev at idle. I stepped on the gas and the rpm just slowly goes up. Before it revs up nice and strong. Any help would be greatly appreciated. Thanks
also what vehicle is this for? I didn't see where mine was..
wouldn't electronics cleaner be the same?
Damage your part to wrong kind of chemical
I have a 2013 honda cr-v it hesitates about the third crank it starts then my check engine light is on and other lights I just put a alternated on today doing what's in your video should that fix the problem or should I look into the full pump it doesn't bog down or skip going up a hill or nothing but when I run the car a bit I shut it off then when I get back in it it starts right up and the check engine light is off so could the mass air flow be the problem?
Thank u for sharing
My 96 Jeep Cherokee has a problem I can't diagnose. The symptoms are similar to a bad/ dirty Mass Airflow Sensor and Throttle Position Sensor, but the symptoms don't fit either exactly. It happens only while driving, not while idling.
The engine will suddenly lose RPM as if it want to die for a couple seconds then will go back up to normal, then down and up repeatedly for a couple minutes then will clear up and run fine for a while. It also seems to "pop" lightly like it wants to back fire but can't.
Would you consider this a problem with the MAS or TPS or could it be something else?
Thank you.
P.S. I've tried changing fuel to a higher grade and used fuel injector cleaner.
If your check engine light is not on, then cleaning the MAF would be a good start.
ok thank you.
I used the spray to clean the MAF, things have become better for some time but after that the same problem started again (car little hesitates and shakes when starting).
