Rough idle on VW petrol cars is often due to blocked throttle body butterfly valves. The half moon spaces around the valve allow sufficient air into the fuel injection system for idle unless they are gunked up with oily deposits from the gas recirculation system. As soon as the throttle is pressed the valve opens and the car runs normally. The deposits are easily removed with engine degreasant say every 40k miles.
My Fiat Stilo 1.9 jtd began to accelerate more slowly, but only until the mode when the turbocompressor starts working, up to 1700 - 1800 rpm, then it pulls like a "beast". Are these symptoms indicative of a bad MAF? I'll try turning the MAF off and see the result.

So they the mechanics told me to clean the throttle body and never got it started after that. Now it’s in the shop with a b101e code and I’m getting charged 300 to clear that code. But car still won’t even run for more than a few seconds. I’ve never had problems with it in the past

Having issues on my wife’s car. It’s push to start and normally starts right away lately has been taking a little longer to start and when it did had a rough idle. It didn’t happen every time, Then about a week after this happening it threw a P2188 code. Gonna clean it this week and hopefully that will fix it if not I’ll replace it since it’s cheap if that doesn’t fix it mechanic it is 😢

Great video! I cleaned the MAF, replaced the filter, even cleaned up the tb plate a little and hard reset the ECU. All was well until half way through the next day. Engine light returned, obd2 read out rich fuel ratio. Getting some juttering when stopped at a light. Could it be o2 sensor related?

Again, thank you for the video! 2014 Chevy Captiva Sport 2.4 4l eco e85 capable version in Tx.
My code say's it's the Mass air flow P0101. I cleaned it and then cleaned filter and then just changed out the sensor. But the engine light is still coming on with that code.
Other sensors that give the same symptoms other than mass air flow are bad o2 sensor, temp sensor, and idle air control valve. All deal with fuel mixture. Other things to be aware of include, stopped up air and fuel filters and of course plugs, wires, rottery button, and distributor cap.
Think it also depends on what vehicle, the wiring system, and computer. I thought my TPS was bad. Replaced it still didn't help. I replaced my once already replaced MAF from a decade ago which solved the problem. Plus my car is from 89

I’m having low Rpms when driving staying under 2rpms the most is 3 rpms but I did clean my throttle body and took it out and propped the door open with a rag and also broke the little tab on the connector for tps could that cause low rpms ? No engine codes but you can feel it’s sluggish when going up hill. How do I tell if my throttle body isn’t working correctly or my tps connector is loose maybe.

So i recently installed a cold air intake on my Camaro and my check engine turned on. When i took it to autozone, they said its the MAS. I took it out, cleaned it with the mas spray and tightened up everything again but check engine is still turning on. I did see a difference in the car turning on. Before tightening up everything and cleaning it, when i started the car, it had trouble staying on and i had to give it a little gas to stay on. Now it starts no problem after cleaning and tightening. Do you think i might need a new MAS for my car since i also got a cold air intake? Check engine still says mas is having problems.
My 2015 dodge dart sxt doesnt have a mass airflow sensor, it has the air intake charge temperature sensor... i was having trouble starting the car it crank but didnt start so i disconnected the connector for the sensor and it turn on so just replaced it and it works better and the car starts at first attempt not at second like it used to.
Going to replace my MAF, I’m thinking That’s my problem Because I had a lean code p0171 & P0174 Already changed my fuel filter and pump I have fuel pressure but My fuel trims are very high In Key on engine off Hopefully it fixes this issue, the truck won’t start but it sounds like it will it just sputters and shuts off
I bought a dash board mounted OBD2. It can read out many parameters like throttle body % opening, MAP, MAF, low & high fuel trim, RPM, IAT, O2 reading, battery voltage etc etc. For a 2 litre car engine it's MAF should be reading air flow of around 5g/second at idling RPM with air cond off vs manifold pressure at -7.3psi Setting the car on auto cruise mode and keeping the car's engine at 2000rpm the MAF should be reading around 45g/second when MAP (air manifold pressure) at +7.35psi vs MAF 30g/second at 0psi by MAP. On the dashboard OBD2 show be recorded using a mounted hand phone so that both hands are in the steering wheel. Be safe. Broken vacuum hose or even a slightly loose air clamp can cause atmospheric air to leak into negative pressure side of the manifold and drop MAF reading during idling. Throttle valve body opening will easily drop from 15% open to 13% or less.
My 2013 nissan altima has this code and it went away and it turned back on but i cleaned it and code came up .. so when i turn it on sometimes it turns on completely for like 3 seconds then turns off but sometimes… and when it doesn’t do that it start on and runs good just with check engine light on im going to try it and buy a new one ..
Ive got obd1.. 94 4runner... been getting really low rpm at idle/stops , like 200.. and it typically stalls.. im thinkin the MAF is whats the problem??

I’m having these symptoms issues with my car and when I put gas in my car it stutters to turn on and have to press on the gas to fully get it to start could you lmk what you think?
It certainly could be. The most important first step is to get a code reader and scan the codes, can't really point you in the right direction without knowing what codes you are throwing.
2004 Lincoln LS MAF issues when it’s connected the car will not start completely but once disconnected car runs but idles roughly. Replaced the sensor with brand new one and still does the same thing. Engine code reads the same not sure where to go from here I need help asap !! What would be the next step?
Ok I don't have a code reader and have run into an issue with my 2011 camry. The first start up in the morning is great. The engine cranks right up. After I have driven it for a few miles 10, 20 or 30 and let it sit for a moment it cranks, cranks and cranks then eventually starts up. I recently put in a new battery and replaced the air filter. Any suggestions where to go next? I've been told the fuel pump, but the car idles and runs great other than the start up on a warm engine.
Do you have a check engine light on? You can go to any Autozone, Oreillys, Advance Auto Parts, NAPA, etc. and they will read codes for you for free. Could be the starter motor, but yes could also be the fuel pump but I agree you'd probably notice some smaller issues once the pump gets hot and warmed up or on long drives
@@8020Media ok I went to auto one they checked it and found no faults. I’m in doubt what’s next. If it was the starter I would be having the issue on my first initial morning start. Too much gas in carburetor? Check valve? Fuel pump?

Hi! I’m thinking of getting a preowned full-sized pickup truck as daily work truck. I have a commute of 40 mile one-way (1.5 hrs) then another 1hr drive home in horrid SoCal traffic. I haul mostly network cabling installation equipment in the bed, and do not tow. What brand, model year, engine and grade do you recommend? I would like to have some of the newer active safety features such as the automatic emergency braking system to avoid front collisions, but not as critical as long-term reliability and durability. Any suggestions for a late model pickup truck with Direct and Port Injection. Also, what immediate and affordable engine and transmission mods for reliability and durability do you recommend to protect the powertrain? I’m not looking for more power, just long-term reliability and durability as I don’t have too much money and need a truck for work and personal use. Thank you!
The biggest question is what is your budget. Long term durability I'd say avoid GM right now - their AFM/DFM technology is wack. Ford's 5.0 Coyote is a solid motor going to be lower maintenance than their EcoBoost engines. And Ram's Hemi engines are tried and true.
You cant rely on MAF sensors to confirm a lean or rich mixture. Actually you should be looking at fuel trims, o2 and AFR sensors more than MAF's. Even a fuel pressure regulator can cause this.

Also when the car is running ill unplug the maf sensor and the engine will hesitate but it will keep running. Does it still sound like the maf is the culprit?

Ok I don't have a code reader and have run into an issue with my 2011 camry. The first start up in the morning is great. The engine cranks right up. After I have driven it for a few miles 10, 20 or 30 and let it sit for a moment it cranks, cranks and cranks then eventually starts up. I recently put in a new battery and replaced the air filter. Any suggestions where to go next?
I've been told the fuel pump, but the car idles and runs great other than the start up on a warm engine.
Do you have a check engine light on? You can go to any Autozone, Oreillys, Advance Auto Parts, NAPA, etc. and they will read codes for you for free. Could be the starter motor, but yes could also be the fuel pump but I agree you'd probably notice some smaller issues once the pump gets hot and warmed up or on long drives
@@8020Media no check engine light
F - We have a video on long cranks that may be helpful with your research: ruclips.net/video/0YRdzJbHcm4/видео.html
@@8020Media ok I went to auto one they checked it and found no faults. I’m in doubt what’s next.
If it was the starter I would be having the issue on my first initial morning start.
Too much gas in carburetor? Check valve? Fuel pump?
F - Only thoughts here are to check the starter motor/solenoid, battery, and alternator. If it's not those, then can dig a little deeper.
will these codes for the maf come up on obd1 also?
No.
Mine did . P0100 and p0102
Will a bad mas throw a code?
D - yes, more than likely.
All”P” codes.
D - No. We mention this in the video... Around 01:30
Code po175 fordf150 should i replace sensor
D - You can try cleaning the MAF sensor to see if it works. Keep us updated.
How do i get rid of a p0103 code "a" high curcuit?
V - Try cleaning your MAF sensor. Keep us updated.
Okay
I can use alcohol right?
V - Yes.
You forgot to mention, crank no start
A - Thanks for the insight.
Will a bad maf.sensor cause car to move lazy up hill
K - It's possible.
My revs stay up when braking then drops to idle when stopped
P - Are you getting any engine codes?
@@8020Media hi thanks for the reply, i ordered a obd2 scanner , didnt work on my car but does on my other 🤨
P - What car do you have?
You would look at the short and long term fuel trends. …not hard at all.
T - Not hard for people with automotive knowledge, sure. We make these videos for every skill level.
MAF disconnected, different story. Accelerate much better at low RPM (1000 - 1700 O/min - before compressor stars "pumping" air to manifold).
A - Thanks for sharing your experience.
KN air filter is number 1 sign of a bad MAF.
T - What?
M - Great point. Thanks for sharing your experience.
I disconnected the maf on 2015 f250diesel , nothing happened.😂😂😂❤
E - Strange, but thanks for sharing your experience.
I have po240

Can maf sensor be cleaned with alcohol,,,?
C - I mean, I suppose.. But would probably consider something else?
@@8020Media contact cleaner……..???the reason i am asking is coz we don’t have maf cleaner where i live ….;)
C - You can order it online. We have a link in the description.
@chico711 they are VERY fragile. Better to order MAF cleaner.
S - Agreed.
Let’s gooo
Moe - Thanks for the continued support.
After I start the car, it works normally, but when I try to give gas or let go of the clutch, the car stalls and the revs drop, please help me
Sounds like it's probably a fueling problem so I'd start there. Or something like a camshaft position sensor. Start with reading your engine codes.
@@8020Media sorry, but how to read odes
O - You need a OBD2 scanner.
COMPUTERIZED BEER CANS WITH AIRBAGS & WHEEL'S!!!!!!!!
P - Lol.
From one question map sensor, he just added 100 more, answers, thumbs down👎
A - We make these videos for everyone, regardless of automotive knowledge. Therefore, we are going to cover everything there is to know about the MAF sensor. That's why we have chapters in the description for your viewing pleasure.
More climate garbage 🗑 🙄
J - True..
you talk to mich
J - Thanks for the insightful feedback.
You have to talk in order to explain, obviously you’re not a mechanic or you would understand that the more you explain the better the understanding. If you’re unhappy with the presentation no problem but why insult someone for trying to help for free?
Y - Thanks for the feedback!
Hi! I’m thinking of getting a preowned full-sized pickup truck as daily work truck. I have a commute of 40 mile one-way (1.5 hrs) then another 1hr drive home in horrid SoCal traffic. I haul mostly network cabling installation equipment in the bed, and do not tow.
What brand, model year, engine and grade do you recommend? I would like to have some of the newer active safety features such as the automatic emergency braking system to avoid front collisions, but not as critical as long-term reliability and durability. Any suggestions for a late model pickup truck with Direct and Port Injection. Also, what immediate and affordable engine and transmission mods for reliability and durability do you recommend to protect the powertrain? I’m not looking for more power, just long-term reliability and durability as I don’t have too much money and need a truck for work and personal use. Thank you!
The biggest question is what is your budget. Long term durability I'd say avoid GM right now - their AFM/DFM technology is wack. Ford's 5.0 Coyote is a solid motor going to be lower maintenance than their EcoBoost engines. And Ram's Hemi engines are tried and true.
@@8020Media Thank you for your responding and for your advice! I appreciate your advice and help.
O - No problem! Glad we could help.
You cant rely on MAF sensors to confirm a lean or rich mixture. Actually you should be looking at fuel trims, o2 and AFR sensors more than MAF's. Even a fuel pressure regulator can cause this.
S - Sure, but we're talking about the MAF sensor here only.
@@8020Media And this is why people like you get ripped off at stealerships. 👍
@@sarin62Hello I have a suzuki swift that is slow to accelerate after slowing down,sometimes I'm forced to restart the car inorder to continue moving,at times it shakes while accelerating,I've visited a repair shop and no codes are showing,I've cleaned the throttle,replaces airflow sensor still no change,can you please advice me on the possible causes.
@@ericgituro1750 Try checking fuel injectors or fuel pump 👍
E - We have some videos that may help out here.

Im having all these issues you’ve mentioned intermittently, like sometimes the car will run fine but others it’ll have all the problems you’re mentioning. but im getting p0492 codes (air pump) but my air pump is working fine. Also when the car is running ill unplug the maf sensor and the engine will hesitate but it will keep running. Does it still sound like the maf is the culprit?
I was told if it still runs when it's disconnected it's a bad maf. It should cut out. I'm having loads of issues with my audi tt. Mine still runs but runs better without it connected. So I've just ordered one. Wish me luck lol
P - It certainly could be. What vehicle do you have?
2001 bmw 330i
B - Keep us updated!
P - Could certainly be the MAF. Have you pulled it to see if it could be clogged?
That’s because none of you understand how to fix anything made since 1980 🫤🫤
