This video is very useful. I finally understand how my car's damaged throttle body was affecting the oxygen sensor and overall acceleration and why my rev meter was out of control. Many thanks!
**watching 'What Is Engine Braking?'** "...the throttle body is going to close..." **opens 'Throttle Body - Explained' in new tab** "...it's located between your air intake filter and piping and your intake manifold." **opens 'Intake Manifold - Explained' in new tab**
Thanks as always, Jason. Spreading knowledge is one of the world's most satisfying careers. Would love to see a video about your thoughts on throttle body spacers.
I never would've thought I'd ever be watching Engineering Explained but this channel has helped me understand why something in my might go bad. Thanks!
Good explanation, thanks. I was looking for videos on which product (throttle body cleaner vs carb cleaner) to use to clean the throttle assembly/valve on my scooter safely, and ended up getting a very useful tutorial.
Great video. One suggestion: on smaller, more involved parts like this, use a diagram or a still shot of it and draw on it in post production to show what you're referring to as you speak. It's not that much of an issue because all the air channels and things like that are pretty distinct here, but some on-screen red lines and circles would do a better job of pointing to specific parts than would your fingers.
Thank you so much, you explained it very well. My 2014 Chrysler 200 just had to have this part replaced, as I had never heard of it before, I was glad that I watched your video. Bloody practically new car and had to have a major fix like that after only 37,000 kmp.. Oh well.
This was a great, concise explanation of a throttle body. Thanks so much, not a huge car guy and I'm supposed to design a throttle valve and do CFD testing on the air flow for my senior design project so this was a good start on the anatomy of it.
omg. now I understand. :D I' want to order a CAI brand cold air intake and while I was searching forums and watching youtube videos, the term "ported throttle body" came up. I'm fairly new to the car mod scene so this video is reaaaaally helpful. Thanks!
At idle it gets more fuel not more air I thought. Please correct me if if I was wrong. BTW I watch all of your videos and I absolutely love understanding how things work! Good work!
I also have request. I am in the propane and natural gas fuel system business. Can you make a video on how a propane fuel system works? Natural gas system? If you need resources I have all sorts!
i have noticed throttle delay in my new car, specially visible in idling speed, engine is very slow to react when i press acceleration paddle, i must press continuously to rive the engine, is this wrong or its manufacturing feature?
Hey man a long time ago I wanted to say thank you for all your videos, I'm a car enthusiast that not only like when cars "look nice", I also like too know how to improve the way they work. I'm thinking about starting my engineering studies and I want to know in what area are you specialized? Is it automotive engineering? Or mechanical engineering?. I hope hearing from you soon. Thank you again for what you do for all those car enthusiasts and engineering fans.
oh wow i was wondering how the engine doesn’t stall when there is no airflow from the trottole body i had no idea there was a bypass hole that’s cool, good tutorial
I like your explanatins, learn alot as a newbie. That sad, RUclips is a global thing and alot of the viewers dosnt have English as first language, like me, so it would be highly preciated if you could talk somewhat slower in the videos. THx.
Wow, this is a very useful video. It really educates me about throttle body. So what makes my Opel Astra H have a high rev every time when I am starting the engine?
Great explanation and very thorough. Can you explain what a throttle body spacer is and how it works ?? I have an F-150 w/6.0L engine. My son says I should put one on and it will help power and fuel mileage. Thoughts ??
Hi just a quick question, I have a BMW 330D and looking to increase the HP available, looking on-line you can get upgrade chips. Do these diesel upgrade chips work? Are they safe? Are they worth it? Thanks for the videos man! Keep up the good work, best RUclips Vids going!
Hello Mr. Jason. I am 13 and I am very enthusiastic about cars and engineering itself. Thnx for all the knowledge you have given me. Just one question, what college did you go to and do you recommend it?
Malachi Williams I went to NC State. It was certainly a challenging and rewarding curriculum, though there are lots of good ME schools. My recommendation would be to go to something accredited and local to save cost.
NCSU is a really good school and pretty hard to get into, almost all of my friends got deferred. That should tell you about how smart Jason is. Just make sure you get the best grades possible and take a lot of science and math AP classes.
Hey do you think you could explain the vq37vhr engine on a video soon? I've tried to understand how the whole camless vvel system works but I just always find mixed info on that topic. If you can I would appreciate it. Great videos. Very informative and never a waste of my time unlike much of RUclips out there. Keep it up.
From what I can find it's not really camless it just works slightly different. It uses rocker arms to hit the valve tappets instead and the way it changes lift and duration is by changes the pivot point in the top control camshaft.
You should consider making a video on Individual Throttle bodies, their applications, their benefits, their drawbacks, etc... I don't know much about them and I'm having a hard time finding information about them. Seems a little unorthodox to run an engine without an air filter... But like I said, I don't know much about the subject.
Do your research and you would know. Spacers are all about adding Volumetric efficiency, (more air traveling through your plenum). This increases MPG, HP in higher RMP range, and keeps the engine cooler providing more cool air for better, more consistent performance output. It's really simple and the information is more than abundant, friend.
I have heard that too large a throttle body can in some cases hinder performance due to slowing down air speed. Any thoughts on how to know when its time to go larger?
you did very good, but you should explain a little more about the anatomy of the tb. like the names and what happens if you adjust that this way and that this way so on an so forth.
'Throttle body heater delete' is a very common modification for the M42b18 that's in my BMW E30. Every horose helps and here in the UK it isn't going to freeze. Hopefully..
I had a situation in sub zero weather in Michigan where I pushed on the gas and the pedal didn't spring back, making the engine rev up, and if I put it in neutral, it was really revving! This is on a 2001 Saturn. Did some condensation freeze it open? I checked the cable to make sure it wasn't caught on something, and then I sprayed on a lubricant after cleaning out the Throttle body. This seems to only occur in the winter, and when I clean and spray, it goes away. Your thoughts, and thanks for your videos. very educational!
Interesting, and quite dangerous! Hopefully you were able to turn off the engine soon. Perhaps it was the throttle freezing, as something had to stick.
My '95 Tahoe does this once or twice a winter, especially in the -10 degrees F or lower range. Usually it's just a little WD40 and a light thump with my hand to get it to free up. A 5.7 V8 revved up to 5000 is a little scary, so I know the feeling of dread when the pedal gets stuck!
Considering this video,another question poped out of my mind and that is when the engine starts,you don t press the accelaration pedal. Therefore,how does the engine suck air to keep running if the throttle body is closed?
So the TP sensor is the one that send info to the PCM to command the amount of fuel that should be injected, or is the MAF sensor the one that determines how much fuel should be injected.
could you make a video explainning the formula used to calculate the right diameter of a carburetor's ventury for a given engine? like knowing the displacment of an engine what would it be the carburetor for it?
Should the throttle plate seal 100% of the throttle body or is it normal to have a very thin line of air? I have an old lancer glxi 93 and my rpm is a little bit high. Hoping to get an answer from you good sir. Have a nice day.
Excellent video. Very informative. My older Ford has a double throttle body. Also, I have seen some with 4 chambers. Why all the different designs ? Any idea ? Thank you. Very well done.
This video is very useful. I finally understand how my car's damaged throttle body was affecting the oxygen sensor and overall acceleration and why my rev meter was out of control. Many thanks!

wow never seen anyone get that detailed on a throttle body before. good job
Yes; exactly what I was thinking
Lla
😮yesss he did an AMAZING JOB! Thank you!!
**watching 'What Is Engine Braking?'**
"...the throttle body is going to close..."
**opens 'Throttle Body - Explained' in new tab**
"...it's located between your air intake filter and piping and your intake manifold."
**opens 'Intake Manifold - Explained' in new tab**
something new
thatz how ya learn my friend
This channel in a nutshell.
literally been doing that for four days.....don't even have a car😭
it's a vicious circle my friend.
Finally someone to explain this thoroughly and in detail. Thank you!
Thanks as always, Jason. Spreading knowledge is one of the world's most satisfying careers. Would love to see a video about your thoughts on throttle body spacers.
This was great! I would like to see more in detail explanations of parts like that! Thank you
I never would've thought I'd ever be watching Engineering Explained but this channel has helped me understand why something in my might go bad. Thanks!
I have throttle body service this morning and I felt significant power when pressing the pedal. Thanks explaining this part.
Hey thanks !You wore so detailed. I never seen someone explaining exactly everything how it works!
Good explanation, thanks.
I was looking for videos on which product (throttle body cleaner vs carb cleaner) to use to clean the throttle assembly/valve on my scooter safely, and ended up getting a very useful tutorial.
You are the BEST,
You ARE the Man.
Thank you.
You are a Legend!
Awesome video! I'd love more like this, explaining the more nuanced parts of a car in detail with a physical specimen to look at.
Great video man. I gotta 88 model chevy small block 350 tbi. You just gave me a much greater insight on the throttle body on it.
VERY helpful... Clear, concise, mystery dispelling video.
Great video. One suggestion: on smaller, more involved parts like this, use a diagram or a still shot of it and draw on it in post production to show what you're referring to as you speak.

Thank you for this video. It dissipated several doubts I had about how the throttle works.
Thanks man. Was researching a throttle body coolant delete and this helped.
Thank you for making videos like this. You are the guy I come to as soon as I need info on cars!
Thank you for explaining this so well, it was extremely helpful. Mine just went out and I had no clue what it was 😂
nice job .. you leave me with almost no question.. this is the kind of stuff we should learn in school.. thank you
Hello, just wanted to say thank you so much for sharing so much knowledge, may Allah bless you & give you great success in life & in health.
I'm glad you took time outta your day from being yellowstones lawyer to explain this too me thanks jamie
My comment is, that you are truly a gift to human kind.
This was a great, concise explanation of a throttle body. Thanks so much, not a huge car guy and I'm supposed to design a throttle valve and do CFD testing on the air flow for my senior design project so this was a good start on the anatomy of it.
Very informative breakdown.👍
Great video! Everything I needed to know about this product, definitely switching to this throttle body.
omg. now I understand. :D I' want to order a CAI brand cold air intake and while I was searching forums and watching youtube videos, the term "ported throttle body" came up. I'm fairly new to the car mod scene so this video is reaaaaally helpful. Thanks!
Simple, Clear and well done.VERY well done !

I also have request. I am in the propane and natural gas fuel system business. Can you make a video on how a propane fuel system works? Natural gas system? If you need resources I have all sorts!
Could you make a video regarding ITB (Individual Throttle Body) and what the benefits are compared to single throttle body
i have noticed throttle delay in my new car, specially visible in idling speed, engine is very slow to react when i press acceleration paddle, i must press continuously to rive the engine, is this wrong or its manufacturing feature?
Tighten your cable
Best video for Engineering students.
fantastic illustration
excellent explanation of mechanism of throttle body
Gave a good explanation for sure though great work dude

Excellent job. You have almost made me an expert. 😊 Thank you 🙏🏼
oh wow i was wondering how the engine doesn’t stall when there is no airflow from the trottole body i had no idea there was a bypass hole that’s cool, good tutorial
2015!!! how come I haven't found this channel before?
I like your explanatins, learn alot as a newbie. That sad, RUclips is a global thing and alot of the viewers dosnt have English as first language, like me, so it would be highly preciated if you could talk somewhat slower in the videos. THx.
Can you pls do advantages and disadvantages of throttle body, carburettor and injection system?
Intake manifold next vid would be awesome
Thanks for the video, mine was replaced yesterday at the dealership and I was just curious as to what it was.
Wow, this is a very useful video. It really educates me about throttle body. So what makes my Opel Astra H have a high rev every time when I am starting the engine?
Great, it's nice to see the part and understand all is component. Thanks.
Damm he's a good engineer he explain it so well.
Very interesting. Thank you very much for posting!
That was very interesting thankyou!! Please do a 20 - 40 test to see what increase you get
none if any
So thats how it is... great information !!! thank you so much
Thank you! Not car savvy and your explanation helped me understand! I appreciate it!
Great explanation and very thorough. Can you explain what a throttle body spacer is and how it works ?? I have an F-150 w/6.0L engine. My son says I should put one on and it will help power and fuel mileage. Thoughts ??
Professionally presented! Well done!
clear, detailed & to the point. excellent
Thanks. Very informative video.
Please explain how a PK PJ 3.0 throttle body works. It only has a kind of a vaccum lines attached. Is it electrical?
Excellent explanation. Really helped me with my project.
Hi just a quick question,
I have a BMW 330D and looking to increase the HP available, looking on-line you can get upgrade chips. Do these diesel upgrade chips work? Are they safe? Are they worth it?
Thanks for the videos man! Keep up the good work, best RUclips Vids going!

Really good presentation!
The video is very helpful. I have a question, is there should be a small gap between the throttle plate/butterfly and the throttle wall?
Excellent and detailed video.
Hey do you think you could explain the vq37vhr engine on a video soon? I've tried to understand how the whole camless vvel system works but I just always find mixed info on that topic.

No english closed caption? Darn...
Just found this video right now... you've earned a new sub!!!
Cool Video! Next one on Injections :) ?
Amazing video bro 👍🏽
Thanks God for sharing your understanding about this matter.
Thank you for this..love your vids..mostly watched to see if I could delete some passages. As I deleted 2 sensors
do you make it always run at full intake?
You should consider making a video on Individual Throttle bodies, their applications, their benefits, their drawbacks, etc... I don't know much about them and I'm having a hard time finding information about them. Seems a little unorthodox to run an engine without an air filter... But like I said, I don't know much about the subject.
I love this channel
This is great finally found out the reason why my car just slowed down while on the highway
Could you also do a video on whether or not throttle body spacers work and if they're worth the money?
What do you think about throttle budy spacer?
You should do a video on Throttle Body Spacers! :)
I'd love to see an explanation of Throttle Body Spacers and if they even truly do anything or not. Too much controversy.
Do your research and you would know. Spacers are all about adding Volumetric efficiency, (more air traveling through your plenum). This increases MPG, HP in higher RMP range, and keeps the engine cooler providing more cool air for better, more consistent performance output. It's really simple and the information is more than abundant, friend.
Fake Name that sounds like a personal problem as that was a cheap one lmao
I have heard that too large a throttle body can in some cases hinder performance due to slowing down air speed. Any thoughts on how to know when its time to go larger?
you did very good, but you should explain a little more about the anatomy of the tb. like the names and what happens if you adjust that this way and that this way so on an so forth.
Great video....I learned a lot !!!..........Thank you very much..........Godspeed....
'Throttle body heater delete' is a very common modification for the M42b18 that's in my BMW E30. Every horose helps and here in the UK it isn't going to freeze. Hopefully..
Could you explain independent throttle bodies? What is the benefit, and what do you sacrifice?
I had a situation in sub zero weather in Michigan where I pushed on the gas and the pedal didn't spring back, making the engine rev up, and if I put it in neutral, it was really revving! This is on a 2001 Saturn. Did some condensation freeze it open? I checked the cable to make sure it wasn't caught on something, and then I sprayed on a lubricant after cleaning out the Throttle body.

Considering this video,another question poped out of my mind and that is when the engine starts,you don t press the accelaration pedal. Therefore,how does the engine suck air to keep running if the throttle body is closed?
Great video. I learned quite a lot!
Can you make a video for properly setting idle control and using the bis screw?
Wow, I just learned a LOT! Thanks for the awesome video!
Awesome explanation. Thanks.
Nice explained all of your videos......do yoy know if the itb's actualy are making big difference?....thanks and keep up the good work....
So the TP sensor is the one that send info to the PCM to command the amount of fuel that should be injected, or is the MAF sensor the one that determines how much fuel should be injected.
could you make a video explainning the formula used to calculate the right diameter of a carburetor's ventury for a given engine? like knowing the displacment of an engine what would it be the carburetor for it?
Great video. Will subscribe.
Great video, always learning!
Thank you for sharing your knowledge.
Absolutely love your channel! You explain so much for me! 💯💯👌🏽
How does adjusting the idle adjustment screw influence idle rpm? Screwing it in = more idle rpm? Or is it the other way around?
Should the throttle plate seal 100% of the throttle body or is it normal to have a very thin line of air? I have an old lancer glxi 93 and my rpm is a little bit high. Hoping to get an answer from you good sir. Have a nice day.
Excellent video. Very informative. My older Ford has a double throttle body. Also, I have seen some with 4 chambers. Why all the different designs ? Any idea ? Thank you. Very well done.
Great job as usual. Thanks
Butterfly on idle should be 100% close ?? Means no need to adjust butterfly adjustment screw ??
anyone went- VRROOOM!!!!
when he activated the throttle?
