Mine never showed up bad with scan tool! But, I changed it and 👍for $30 on Amazon! Runs perfect 🤩

[erikthered]

I had intermittent stalling issues at start up or would stall at highways speeds. It was frustrating. I back probed the MAF and viewed the live data on a scan tool while driving and saw no issues. Then again, the issue wasn't present when I did that, of course. This was after changing the air filter and cleaning the MAF. No codes. Replaced the MAF and the issue went away, never to return.

[way]

Just replaced this part, which is super easy to do, and I know nothing about engines. I'm checking this video, and I had all 4 of the first symptoms. $30 part on Amazon.

[CatchYourWave]

Very on-point and consistent use of graphics. They don't come off too salesman-like or automated.

[AdriosElJefe]

Ok this is the most accurate video to what my car is experiencing. Should I just clean the sensor before buying a new one?

[coarsegrind]

My transmission was shifting erratically. No codes so I kept driving it easy. Two or three days later I got a MAF code. Cleaned the MAF and the shifting improved.

[DanielGomez-cfvk]

My 2005 Kia optima stalls at red lights got a $20 dollars MAF sensor and all good now!

[scrutinizerone]

I replaced the MAF sensor myself, I got the part for $36.00 and the car has no problems. And also, the part was GM OEM. $300.00 to $400.00, unbelievable.

[toysoldier]

My MAF sensor is way less than $100.00. Your best bet is to shop around. This is usually an easy part to replace yourself at home. Just ensure you have the proper screwdriver (bit) for the job.

[M_arment]

Quick summary. Pull the sensors plug out while engine is running. If it stalls- sensor is (probably) good. If it keeps running with the electrical harness unplugged, order a new one or try cleaning it with MAF cleaner.

[davidwang]

Well explaination and great figure demostration. Easy to understand. Thank you very much.

[jamesbowen]

1 alwYs routinely clean MAF sensor with SENSOR CLEANER or isopropyl alcohol.
2 repkace with new one evry 50k miles.
Most MAF Meters, including SENSOR are 15-30 dollars on Ebay, less common ones run 25-70 .
Simply clesning a sensor will quiet down, smooth out your engine and increase performance and fuel economy.

[alisalim]

Thankyou for this

My car had a problem with gearbox (or thats what we thought), it had jerking while accelerating and sometimes it looses torque, you can floor the pedal and it doesnt do anything

It showed check gearbox icon

We replaced the gesrbox as it had obd || scanner code and also there was a humming (i beleive we couldbe prevented the costly repair if we had diagnosed it correctly accordin to the symptoms also not thr codes only)

After changing thr gearbox thr shrugging / shrudding/ jerking was still there, no gearbox icon no humming though, just puzzling

I thought to just check for myself and not to just count on mechanics,

Did as this video said, tested by unplugging the sensor (had mechanic with me), no change in sound or performnace of engine, told him that this sensor is faulty, he briught another one and we tested the same wsy and it turned out its the culprit😢

I tested the car and the jerking VANISHED. 😊

I suppose the torque or accelerstion loss will also be gone

Now am thinking if we had just replaced the sensor and changed the gearbox oil we couldve continued using the old gesrbox wihout changijg it (cost upwords of $500) 😢

[tedwright]

My local shop tried 3 different MAF sensors on my 95 4runner. It wouldn't run with any of them. They put a junkyard sensor on. It runs wonderful but won't pass smog. Toyota no longer makes or provides this sensor. I'm afraid I'm going to have to junk the vehicle. Sad because it has a new engine with less than 10000 miles. If I lived somewhere other than CA it wouldn't be a problem.

[dreamlinehdhdclan]

You may not need a genuine OEM but the maf sensor is not a part to cheap out on. Especially with a more performance car or if you want the engine to last

[Xscapeplan]

I would suggest changing spark plugs and possibly the coil pack too while your at it

[PlyBoy-hd]

Misfire is the worst nightmare of any cars because it's may be spark plug or coil or tiny hose or fuel pump injector or bad booster it's will drive you crazy

[cvndizzzle]

I took my vehicle back to the dealership. They do all kinds of test and tell me nothing is wrong. They clear the code. And I leave feeling like things are good but then drive like a day a the engine light comes back on. Autozone checked it and it says that sensor 🤷‍♀️ I’m gonna look at it tomorrow lol. All these symptoms, Shakey idle. Accelerates like it has to think about it. And more money for gas.. 😒

[MechanicalGuy]

Good job guy, i quite like your channel too,
