      Could this cause a car struggling to stay started on a cold start? I noticed after checking my MAS it was completely black in which i could not get rid of the Residue when spraying it. Once my car has started warming up the idle smooths out with no issues after through out driving the car. I have no check engine lights nor codes. I’m totally confused as to what the issue is. I also change the spark plugs.

      I don’t have a check engine light on but I recently checked my cabin air filter and it was really dirty with leaves and debris… the next thing it effects is the MAS correct?

    Hey your a good teacher but if you want to be an excellent teacher do this simple thing slow down. You masterfully understand these different things of how a car works but your viewer is not a master talk to people as if they are children slow down how you explain things and you will be the best teacher you could be.

    Always enjoy your presentations.
    The ECU and details on how its works would be appreciated.
    Do they come from one or two manufacturers, then just programmed to the car company specs?
    What do you offer in terms of getting the live data out and examples of this.
    What do you think the 2020 and 2021 scanners models are going to evolve to?

    Outstanding Vid.
    The explanation of the Mass Air Sensor and how it works and what it does, helped me to better understand the Air Intake system and how it effects Gas Milage.
    The Visual Inspection under the Hood of the Air Intake and associated system Components was also good. looking for loose parts and Leaks, that is Good stuff.
    Well done, Keep up the Good work.

    You are absolutely amazing! Thank you for the great enthusiastic, upbeat, and thorough lesson. Was going to use vinegar in a spray bottle to clean the sensor. So happy I looked into this first.
    One question. Can't seem to find how to clean the fixed filter in a 2004 Lexus RX 330. Do I have to replace the whole filter housing? The inside is full of, what appears to be, nesting material. It is my mother's car and it only sat for 2 months, intact. We replaced all of the coil packs and spark plugs. Codes read 5th coil pack malfunction. When we were ready to replace the housing and new filter, we noticed the fixed filter on top. Then noticed the sensor definitely needed cleaning. And the inside is nasty.

    Other instructions via You tube recommend spraying the inside of the Mass Air Flow Sensor with Mass Air Flow cleaner but you did not. Why? I am assuming you alluded to the reason why when you spoke about the internal circuit board.
