Why does the engine in your car shut off when you come to a stop? Error code P0102 or P0103 - VOTD

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).

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😁

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

Hi Robert, You are just a mountain of information, Thanks for the great video, Cheers

[reginaldharrison]

Man that sounds like my problem. I changed almost every thing thank you so much.

Yes, great point for sure and I like how you say buy some maf cleaner to clean out the throttle body 20% of time it works and then you mentioned 80% of the time it’s the maf, one way to know if the maf is bad and without spending $250 on a new one, unplug, the maf then with the engine running if your car runs ruff then you have a good maf sensor, on the other hand when it’s unplugged it runs normal then it’s good.

Robert thanks so much for the advice on your video 👍🏻🇦🇺

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.

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.

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!

[jsegura]

Thanks for the great details. Right On.

[直语直言]

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.

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

[davyarthurs]

Vacuum leaks can also cause idling issues. Cheers Robert

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

[jacquelinemejia]

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

[yonikenLERi]

Thank you very much for the information that was on point

[tomasbrito]

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.
