- In this video I explain the main reason most cars stall, shut off, or die when you come to a stop at a red light or stop sign, then start right back up and run as long as you have your foot on the gas pedal. Most common problem is a bad MAF (mass air flow sensor).

Hi Robert, You are just a mountain of information, Thanks for the great video, Cheers
You are welcome. Thanks for watching.
All the way from South Africa, thanks for your help,I like your videos,keep em coming.
Thanks for watching
Great explanation and video! Thanks, Robert!
Glad it was helpful!
Thanks for the great explanation of why your engine might stall,changed mine after changing several thing's😡it's been running great for 3wks now😁
Awesome!
Man that sounds like my problem. I changed almost every thing thank you so much.
You're welcome!
Thanks 👍 bro 👋 well explained and it seems like that's exactly my problem.
Will check it out as day breaks.
Blessed 🙏
Thanks for watching.
Robert thanks so much for the advice on your video 👍🏻🇦🇺
you are welcome.
Thank you for your time I appreciate it. I also noticed in my car loss of power when accelerating I feel I could temporarily unplug it to see any improvement

Thank you very much for the information that was on point
Thanks for watching
Thanks bro helped me allot man!!!
You are welcome
amazing video robert. i never knew a bad MAF sensor could cause a running car to die. to my knowledge i thought it affected the ability to actually turn over a vehicle and make it run. Scotty kilmer has a video about it and the information that absorbed was ,the ability to turn over a car with a dirty MAF was incredibly hindered. By the way would love to see a video on bad freeze plugs causing coolant leaks.
I don't use water in my coolant system. 🤔😉
thank you so much , you helped me a lot and you should keep making videos , your good at explaining
Thanks, will do!
Funny thing just popped up on my notifications. I was just coming back from the store and was thinking how much better old girl was running since I changed the MAF. She wasn't idling or running well at all. Before I changed it she was a slug, but coming up a steep hill just now and had plenty of power. One comment/question for you. Sometimes stalling at idle can be a bad or dirty idle air control valve right? Would this era Volvo have one? On some cars the computer just keeps the throttle plate open ever so slightly instead of having and IAC I think. Thanks again for your videos, sometimes I watch em for issues my car doesn't even have because they are to the point and well done. That and, with an older car you never know...could have something go wrong at any time. Keep the shiny side up mate!
On the cars built before '99.
@@RobertDIY I have also noticed she'll cough a bit on startup after a long heavy rain. Sound like any pattern failure or common problem you know of? She almost always fires right up. Did put in a new coolant temp sensor once when the problem was every day, but since no issues....just coughs and takes two or three tries after a heavy rain.
Thank you, very helpful
You're welcome!
Great video
Thanks
Thank you , i will try your advice
thanks for watching.
Nice! Thanks brother!
you are welcome.
Thank you 🙏🏽
You are welcome
Thanks for the great details. Right On.
You are welcome
Good to know!
Thanks for watching
Very nice video. I have a relevant issue with my car. When i press the clutch to change gear or stop, sometimes the engine immediately shuts down (rpms go from 2000-3000 etc to 0). I tried to clean the map sensor and the idle valve (both of them had some dirt), but the same happened again. I don' t know which of the two is causing the problem because the ecu don' t have any error. Everything else (engine performance, idle speed etc are perfect). Do you have any idea?
Clean the throttle body. If that doesn't help, you may need to have a shop check it to see which part is failing to function properly.
Thank you
you are welcome.
I deeply agree what you said about the reasons of car stalls, my just stalls at stop lights, but it is ok at idle without problem, would tell me what are the problem would be, I will appreciated.

My 2000 volvo s70 had the rpm dip down to 700 rpm when coming to a stop. (Its automatic) it never actually stalled but it acted like it wanted to. It got worse and worse until I decided to clean out the throttle. Sure enough it was dirty and after cleaning it the rpm never fell below 900 rpm when running, the result being dramatically smoother stops. I can finally stop at stop signs and not freak out that my car’s going to die.
Those ETM's go bad.
Vacuum leaks can also cause idling issues. Cheers Robert
Yes they can, but usually don't cause stalling.
Thanks very much for the info... I have 2013 Toyota corolla and I experience the problem only when AC is on...could it still be the mass air flow sensor?
ac compressor could be locking up.
I'm experiencing the same with a 06 jeep commander, shuts off when off in park
I have a Volvo turbo 1989 automático trans, Amy how I chance the MAF sensor but still shut it off, check all the hoses but still can't find the reason WHY every time I break shakes and shakes then turno off love your videos and Many times I explain what You Say yo My mechanics THANK YOU
Shanking while braking is due to bad rotors.
Where did you get the replacement MAF?
Hey Robert this is exactly what is happening with my 86 cabriolet automatic. I’m not sure if it has a mass airflow sensor given it’s age. Any idea of what else could trigger this issue? There are no vacuum leaks according to a mechanic that inspected my vehicle and electricals look good. Help! Desperate 😂
Idle valve.
My 2013 Kia Soul is having a problem. Dealer has not found the source. I've had it tuned up, flushed the transmission, all good but not helping. It dies (once in awhile) at a red light, starts right back up, but sometimes it really is hard to get it to gain speed... no amount of trying to give it gas helps it for several seconds. Like pushing the pedal to the floor doesn't affect it. Then the car slowly builds up speed and get back up to say, 40 mph. Engine light usually stays off, or will go off. When I took it to the dealer, it did not come on. Someone told me it might be a powertrain control module. Could it be a mass air flow sensor. Any other ideas? Replacing the PCM is costly at my local dealer. THanks in adance.

What if you have an old school, got a 76 Monte that’s doing this problem but dosnt have any codes right?
Have to troubleshoot it.
I have a Honda element 4 cylinder with a rough idle sumtimes I changed the spark plugs and the air filter is basically new it cuts off when I'm trying to start it not to often but I do have a oxygen 02 sensor code, so I need to replace map senor are o2 oxygen senor I'm clueless are maybe just clean all the carbon inside the air throttle ???
I doubt that. Fix the codes and look for vacuum leaks.
Mine stalls coming to a stop or coasting down the road. No codes being thrown. Iv cleaned the MAF and the throttle body with the two correct cleaners. Buick 2007 3.5 motor.
Have 01 Toyota Camry,starts well but wants to die on idle and does not run smoothly, had a code P0106,P0420,P0770 ,P0106 P.
What do you think?
I think you should Google the codes.
I have a manual 2001 Mazda 626 at stops if I don’t give it gas the car will turn off completely do you think it’s the same problem as in y the video
th-cam.com/video/NhtUXZTurzo/w-d-xo.html
Ive had this problem. A rough idle at start and difficulties staying on. No codes ever popped up so family had to take car everywhere to get it checked. Problems other mechs thought it would be where.
1.Faulty pump relay
2.Faulty gas pump
3.Map or maf sensor
4. Dirty throttle body
5. Spark from plugs
6.spark plug wiers or coils
What ever the problem was. Mechs never found the problem so. We sold the car.
Dang, probably old fuel pump.
I just love you Robert💙
Hey boss any reason why my car starts doing that only when it falls under half a gas tank
I don't even know what kind of car you have. Likely something wrong with the fuel pump sending unit.
Thanks
You are welcome
I’m having same issue in mini van. I’ve replaced the engine filter.. idle air control.. throttle body clean. And cam shaft synchronizer . Any help would be greatly appreciated. 2006 mercury Monterey . One owner. 90k miles
bring it by.
@@RobertDIY where are you located ?
my peugeot 206 would start normal but would died after 2mins of driving once i release the pedal. and the same thing happen on idle - died after 2mins of start. i would managed to restart it after several attempts and would be good for the day untill i parked it for more than an hour, then the problem start again. What might that be please,.any ideal?
th-cam.com/video/NhtUXZTurzo/w-d-xo.html
What if I changed my maf twice already also changed the throttle body in case it was dirty also changed my fuel pumps. And my car won’t stay on anymore when it did stay on it turned off on me when driving slow. The only code I’m still getting is the maf
Where did you get the MAF?
I have this same issue exactly. Works fine while driving but stalls sometimes at intersections. but the code is P0452
Ouch
Hi sir I have Chevy van 2006 I have problem when get slow down shut off I changed lot of things what ever Machanic know but still I have same issue plz guid me thanks

Hi, I had the codes p0101 and p0104 and cleaned up the MAF sensor. It ran well for 2 weeks and the light is back same codes. Tried to get a new one from ford but it's discontinued, I got a different one from Napa. Now the car turn off when I stop. Any suggestions after replacing the MAF?

Thank you!!
*sorry p0171 and p0174
Maybe you can find a good used one from a salvage yard or off of eBay.
@@RobertDIY thank you so much for your suggestion. I reset the ecu and it seems that it's working fine, but it's been only 2 days.
But what about if my car does not have the check engine light on but have the symtoms you just mention
Have you scanned for codes? Does the CEL work?
th-cam.com/video/c_MJwY1fabE/w-d-xo.html
Hello, I’m having this problem but I have changed both mass air flow sensors and throttle body
th-cam.com/video/NhtUXZTurzo/w-d-xo.html
How often do you find the check engine light burned out?
Ever.... they will long out last the car.
All the time. Mine is out in my yellow car. Sometimes they are missing. 😳
You dont need to tke time and check it. You will know its out when cycle the key to start and it fails to light up.
Exactly.
So what I replaced it and it is starting stall out and die at stops or trying to go in reverse
I don't understand what you are saying.
Damn brother we not ignoring code we just broke🤣
LOL Dang. I feel you.
how about when you get no codes? Starts right up and runs great until next stop. Again no codes.
I have no idea.
Hey I have a 2011 Nissan Altima sometimes it runs good but sometimes it doesn’t want to go over 2,000 rpms

Hi Robert I have a car that was stalling at red lights and stop signs and I put premium grade unleaded petrol in my tank with a bottle of octane booster in it and after doing 100kms on it I've noticed that my car is not stalling anymore. I also unplugged my mass air flow sensor plug and plugged it in again and I'm not sure what fixed my car stalling. Have you any ideas on what would have fixed this problem? 👍🏻🇦🇺
🤷🏾♂️ Have you scanned it for codes?
@@RobertDIY no I didn't scan it for codes bcoz I don't have that scanner. Maybe I was just lucky? 🇦🇺
I have a 2000 S70 with ETM that struggles to idle and occasionally stalls when putting in the clutch or in neutral while the car is rolling, but when I come to a complete stop, the idle corrects itself to ~850rpm and doesn't miss a beat. It only struggles to idle when the car is actually moving. No codes or CEL.
Who told you that it is an ETM issue?
Nobody told me it is an ETM issue. I was merely specifying that my S70 uses an electronic throttle module, not a traditional throttle body.
The ETM might be malfunctioning in a different way though, because the throttle does not close quickly enough when letting off above 5,000rpm (putting in clutch pedal and letting off the throttle pedal results in the engine revving even higher, before finally going down). It doesn't do this at lower RPMs, say, 4500rpm, even at wide open throttle.
I guess it's how you read it. I know that all Volvo's post '98 have ETM's so...

My car pulls smoothly and strongly all the way to redline at WOT, starts up after just a second of cranking when cold or warm, and idles perfectly fine as long as the car is fully stopped. It shows no symptoms of fuel starvation at all, besides idling abnormally low only when the car is rolling and effectively in neutral.
I'm thinking it may be MAF or sensor related, because the car obviously corrects the behavior when it thinks the car is stationary, but it doesn't when there's forward speed to be registered.
Robert my car turns of when I come to a stop sign what is the issue it’s a 2008 cobalt
Did you watch the video?
Yes
I have a 93 Chevy Caprice that runs Great except for only 1 problem it dies on me at complete stop or while I'm braking but cranks right up no problem but it flashes INFL.REST. ON DASH ALONG WITH Service Engine
ouch
Did you found what was the problem ?
? Could the Cyatlic converter cause your car to shut off?
If it's totally clogged. It gets worse and worse. Usually slows down the car on highway speeds, then looses a lot of power, then makes it drive under 25 mph... if you're not dealing with it by then, you need medication.
yes I changed out my mass air flow sensor…still doing it…
Cool
@@RobertDIY how???????? you know other options?….
Try to clean your throttle body, EGR Valve and check your fuel pump
@@ramiahwhitney1946 I have no clue what those are 😂
I have nissan sunny b13 with efi engine QG15de when i stoping the car rpm go down and engine shutdown
th-cam.com/video/gLoO-D4yOcU/w-d-xo.html
I have this same problem but MAF not showing up on scan only bank 1 Oxygen sensor
The code system triggers when certain limits are exceeded. Could be a few things but MAF/MAP are most likely. Did you check pending codes?
My van would shake at stops I just put in neutral n it's fine well not fine but it still turns on for now lol
Probably has a bad engine mount.
Hey I have a 1993 car and it died out when I put it in dive or R
Ouch
Just changed my sensor and its still shutting off :(
What code?
@@RobertDIY PO113
Sounds like you got another bad sensor. Where did you get it from?
What if no error code it stall when you stop and automatic transmission
I have no idea. I don't even know what kind of car you have.
@@RobertDIY audi a4 b7 2.0tfsi cvt/tiptronic
How can I find out if no check engine comes on???
have it scanned.
How can you find out what?
About what's wrong if no codes? My 2016 f150 is stalling more frequently now I took the truck to the dealership but they couldn't find anything wrong with it
If you suspect the fuel pump, they can check fuel pressure.
Did they test the battery?
I going to try do it i have fiat stilo 1.6 76kw and some time when i go downhill or stop i press clutch and car dies and i have engine light and when he do die shows me red lights for oil and battery and some time start in first and some time need some time but in the morning when is cold starts in 1 time
Ok.

Ty going to try that but going to chak this too may fix problem because waiting my cosen by tool for obd for his renault so I can juse it too :D
Aren’t you in Cincinnati??
No, but I do live there.
@@RobertDIY ok snap
I wasted 150 for a flashmasters ecm it got worse, it's a 2007 Chrysler 300 .
Ouch
What if my car has no check engine light on and turns off when im at a stand still then when I go to take off it turns off
stalling?

Apparently my Hyundai Getz 2004 1.3 litre doesn't have a MAF
Does it have a MAP?
What kinda crap is this Robert? Where's the rip kit?
Maaaaan i miss opening the hood on our 850 and seeing an engine in there
I haven't installed the one for this car yet.
What's taking sooooooo long? Lolol
That's what I was thinking about you getting your 850 engine back in?
Robert DIY not yet... Wanted to replace the engine wiring connectors. Wife wants to sell it now :(
