    Thank you a million times for this vid. My 2004 F250 5.4, bought new, was having issues losing power uphill and under load at 85K mileage. Took it to four mechanics over the last 1.5 years. No one could figure it out. One told me the truck's engine wasn't powerful enough and that's just the way it was built. Not! I've driven and towed with this truck since 2004 and never before had this problem. The most recent mechanic at a Ford dealer said it was the transmission and wanted to take me down that rabbit hole but I intuitively knew that wasn't the problem. I had already taken it to a good transmission specialist and he found nothing wrong with the transmission. But, then I found your vid and, sure enough, the sensor was bad! $140 cost to replace and I am now driving with no power loss and ability to tow my horse trailer up hill on the Interstate beautifully. Just as it was built to do!

    I've been an auto mechanic for over 20 years. Many of the problems I see daily could have easily been avoided by simply following the vehicles maintenance schedule. I use a program on my computer called Automotive Wolf car care software to keep track of all the maintenance for my 3 cars, a truck and even a generator. It automatically can send you text message reminders when any type of service is due. Two of my vehicles have over 200,000 miles and have never needed any repairs. Want to save money? Follow your maintenance schedule!

    Don't run without your sensor. That sensor is designed to measure airflow. Yes, your vehicle runs for now, but unregulated airflow will throw off the air fuel ratio, resulting in an offset spark resulting in long-term engine damage. If you haven't replaced it, I highly recommend you do. I'm a mechanic and see this all the time.

    That's because this video will cause viewers who are inexperienced to misdiagnose the problem. This particular vehicle may or may not represent a small percentage of engines (or it's a very old model without O2 or MAP sensors) as most engines WILL CORRECTLY NOT KILL the engine when the MAF is disconnected (I haven't seen an engine that would die regardless if the MAF was good or not). When disconnected, the ECU will go into a default mode where it will rely on other sensors such as the MAP and upstream O2 sensor (A/F ratio sensor on newer cars) to calculate for a 14.7:1 air/fuel mixture and continue to run. Apparently, "Proclaimliberty2000", is not a mechanic and will cause more problems than help and was wise to add that long disclaimer. He may have good intentions or may be deliberately screwing with people; I don't know but I have nothing to gain by advising that no one trust him when it comes to engine diagnosis. In this day and age, four things are needed to reach a 100% absolutely correct engine diagnosis (although less will do in some cases). Those are: 1.a scan tool that is able to read live data and display freeze frame data, 2.an oscilloscope, 3.the factory car specific service manual or access to your vehicles specifications/values for parts that may be causing an issue and 4.at least a general understanding of the mechanics and the CAN Bus OBD II system that exist in all vehicles today (OBD II codes are the same for all car manufacturers, unlike the older OBD I systems). Hopefully, you'll at least watch a few other videos. You can't trust the first one you watch on You Tube without sometimes regretting it or worse, creating more problems. Good Luck!

    This is a short 2 minute video (I have no idea who the channel belongs to nor do I have anything to gain) that advises if you have an issue that causes your vehicle to start, then it stalls; disconnect the MAF. If that corrects the problem and the vehicle continues to run with the MAF disconnected, then the MAF sensor is bad and needs to either be replaced or in some cases, cleaning it properly and with the correct cleaner (MAF cleaner, electronic cleaner, brake cleaner, etc) may correct the issue. The reason is that the bad MAF sensor is sending incorrect data to the ECU but by disconnecting it, the ECU can't use the bad data (either very lean or rich condition/engine needs a 14.7:1 A/F mixture to properly combust) that is causing the engine to die, so it then relies on other sensors. Hope this explains the many dislikes here and helps. kzread.info/dash/bejne/f2Whj9BuotvbgdY.html

    If you read the schematic you'll see most MAF sensors contain a temp sensor as well. The correct way to diagnose is to disassemble the connector and remove the MAF signal wire. Reconnect the sensor and drive while watching your fuel trim numbers. With the signal wire disconnected the ECM will substitute values so it can run without the MAF signal. My rig showed LTFT (long term fuel trim) numbers high while driving. Plus 10 to 15 percent added fuel. With the wire disconnected the fuel trims were normal plus or minus 5. Replaced the MAF sensor. The ECM relearned the correct fuel trims during the next cold start warm up. This test is more accurate than just guessing like this video shows.

The mechanic did mention last Jan 2023 that it may go bad and to replace it but mind as well clean the MAF first to see results. After cleaning it, all was good until just few days ago and today, I started to have that same problem and this time it went dead on the road. Had to park on the side to restart the engine again.

    I have Cx5 2014 sport, 6speed, 135,000 miles, I've had spark plugs & tune up, misfire coil wire #2 changed. Ran well, for two weeks ago, I recently noticed some hesitation & jerking again, upon stepping on the gas going up a hill, was only able to go 5 to 10 miles smh. I ordered the MFA oem part, and hopefully, this will fix the issue. The car has been to 2 garages, totaling $500, and I've heard hope its not the engine or something else from them.

    Same story here with a 2016 Kia Soul+. One lone misfire on cylinder #2 code, that never came back. So no codes to go on for 6+ months. Changed plugs, coils, battery, filters, cleaned fuel injectors. Took it to 3 repair shops. Spent $$$$$$! Last shop said maybe it's in Limp mode with no code? Or maybe it's the transmission? Called the Kia dealership twice $200 to put it on the first level code reader, $+++ after that! Kia even said maybe it's beyond repair! 😢 At 133,000 miles!? It went from great car to 40 mph tops, then to 20 mph tops over 6 months. Won't climb the smallest incline. Jerks, rough idle, can't press the pedal down even halfway way or it starts knocking under the middle passenger's side. Barely no forward power, and jerky Fuel economy dropped from 30 to about 10 mpg. Runs best upon starting for the 1-2 minutes between "cold" & "neutral". Doesn't go over 2000 rpm. Seems like it doesn't shift out of second gear. But no codes! Just a quickly flashing oil light after it's been running for awhile, but I've checked the oil dozens of times & it's always full. A lot of weird symptoms! I'm gonna try this MAF test & see if it's that!

Went through the Shop Manual, watched hundreds of KZread videos, went on G6 Forums, tried dozens of things but no good results. Everyone had a different opinion of what the problem was. All pointed to very expensive repairs. I was in despair so i decided to pray for a solution and within minutes your video came into my view. I went out to the car an pulled the sensor plug and the car kept on running. Ordered a new MAF Sensor online $35 buck plus shipping. Thank you. God Bless.

I have to question about the engine shutting off by just unplugging the MAF. Just clean the MAF and see how the car runs. Check the vacuum hoses etc. that can cause a lean condition. Check some other KZreads for other things that can cause an engine light associated with the MAF.

    If the car doesn't turn off your maf sensor is bad or the connector is bad if u have a rough running engine when the sensor is connected cleaning it might fix it but if the engine doesn't stop at all when u dissconnect the sensor then your maf sensor is bad Because maf sensor cleaners clean the sensors and they work only if the sensor was already sending signals or working poorly atleast If you pull the connector and it turns off then the sensor is working "even if it was working poorly it would turn off" It will stay running if the sensor is bad This is my thought about maf sensors if anyone thinks that am wrong pls correct me 😁

    The idea of Mass Air Flow Sensor cleaner is not to fix a faulty MAF, it's to KEEP IT CLEAN so it doesn't crap out. Another sign of the MAF being dead is the car running rich, and I mean halve your fuel economy rich, blowing fuel smoke by the bucketload and getting worse as the throttle is opened more. Plugs often foul and cause misses within 50miles or less. Contrary to popular belief due to a "Pimp my mum's car" kids show from England, check engine light doesn't necessarily just mean a faulty O2 sensor! 😂 😂 😂
