Just cleaned mine today following your excellent video. Job went perfectly and while it didn’t look that filthy it’s made a big difference. The car was difficult to shunt around at low revs and always wanted to stall. Now I can easily move the car around just using the clutch with the engine idling. Power delivery is also more linear and the hesitation below 3,000 rpm when cold seems to have resolved too. I’d recommend to anyone to clean their throttle body. Thanks again for making such a clear video. Really appreciated.
Thank you for sharing this video. I needed to clean it but was afraid I’d screw up something. Felt confident enough to do it after watching you! Thanks!
I'm normally quite proficient doing R&R, but recently I was reassembling and installing my throttlebody and things just didn't seem correct found your video which showed hose routing and by gosh I found that the previous owner installed the throttlebody 90 degrees wrong???really who would have thought it was possible? The car ran fine never had any issues either. Great video it showed the error of ways!
Brilliant mate thanks. At 61 I’ve decided to start doing my own maintenance thanks to channels like yours. I’d just come back from the shop with MAF sensor cleaner and thought what about the rest of the pipes? And here we are! My 2006 has had regular services but I don’t think this has ever been cleaned? Cheers mate from NZ.
Mate that’s awesome and it’s never too late to learn especially when you can save a few Dollars/pounds. If there’s anything specific you need just let me know and I’ll do a video 👍👍
Never worked on anything on my car as have no knowledge on it but had this issue where my revs where going up and down when in 1st gear. Anyway thought I’d follow this video to see if it did the job and it worked ! Couldn’t believe it. Thanks for making the vid, super super helpful and clear
Brilliant 👍thank you for your advice my had idle issue almost stalling, took it apart cleaned and car runs like new now🎉 tbh it looked like newer been cleaned before
what i good video need more like this i clean my today and really feel a big difference and performance. thank you. i don't need to go to a mechanic to rippe me off.
Thank you Jose, really pleased it helped. The next couple of videos will show how to remove the rear light clusters to replace the seals and rear bumper removal to treat the rusted crash bar
Once again Jacko, I was filming the liqui moly valve cleaner, that you insert a long tube and spray over the valves themselves and didn’t remove the throttle body, but I will include your link 👍🏻 for those that want to do it in more detail etc, I may even remove mine and see how the cleaner did.
Lol great minds think alike, I think it’ll be an awesome idea to remove the throttled body after you use the Liqui Moly just to see if it actually makes a difference. I would personally do a before and after video
@@jackos5s too late I did the treatment last night, typically after I turned the camera off loads of crap came out the exhaust and it runs a little better.
@@dss199 oh bummer! I suppose like you say take it off in a few weeks or so and do a review, it’ll only take you 10mins…. Just watched your clutch pedal and cable adjusters. I don’t have adjustable suspension but they are a great idea
@@jackos5s yeah makes life 10 times easier with adjusters, with 32 clicks of adjustment your always fiddling. I may do the intake cleaner on the old man’s mk4 instead, has done similar miles to my mk3. Would be great to see a video on how to disassemble the rear calipers as I plan to paint mine but the whole wind them back thing makes me nervous.
@@dss199 removal is a right ball-ache, i painted mine last year, make sure you have a couple of days off using the car because things will go wrong lol
hey thanks for the vid. i keep seeing things about not scrubbing it because there's some sort of coating that if removed would cause the TB to not have a proper seal and have high idle. any thoughts?
Give it a nice gentle clean with brake cleaner, make sure nothing goes in the electrical system though and it’ll be fine. The “coating” is from factory but soon disappears as soon as you get carbon build up on it . 👍👍
Hi Buddy sorry for the delay, thank you for the feedback. You should really get a new sale. However if the old one is good enough stick it back on you’ll be okay and you’ll save a few pound as well.
Hi buddy, it was a bit of a pain but I sealed up the electrical part. Cleaned it with soapy water and a toothbrush, once dry I used a wire toothbrush then cleaned it with carb cleaner. Once dry I taped up the inlet and outlet with tape then sprayed it with silver aluminium spray paint. 👍👍
Great video! Much appreciated. Is it okay though to open the valve manually since these are electronically controlled? I've read in other forums that an electronically controlled throttle body should never be pushed open manually. Basically, it means we can only clean the TB on both sides with the valves down. What do you think?
Thank you for the kind words, the “rule” book states that you shouldn’t move the flaps to clean inside. I’ve ignored this “rule” for several years and I’ve had a problem! But this is your risk, you can see if it opens/closes when you press the accelerator with the ignition on but the engine isn’t running.
Hi Buddy, remove radiator cap, turn on the cabin heating to full, put the cabin fans on to max then let the engine run until normal running temp. This will remove all the air
Thanks for the reply ref the expansion tank 👍 Back to the throttle-body cleaning. Do you use brake/carb cleaner or the "proper" intake/throttle-body/MAF cleaner? As there are no obvious plastic parts inside the throttle-body. I assume it's perfectly safe to use brake/carb cleaner or even 99% isopropyl alcohol. From what I can see, the "proper" stuff is made from the tears of a pregnant, virgin, Patagonian gypsy. Who was born at precisely midnight on the 29th of February. In other words, it's a great bit of marketing & misinformation. Designed to add lightness to our wallets 🙄
Brilliantly said and I couldn’t have said better myself 😂😂 I used break cleaner that cost £2.97 from Halfords, I just made sure the electrical components were taped up
Hi Jacko, I see you still have the original expansion tank & it's nearly as yellow as mine. As you are so fastidious with every other aspect of your MX-5. Is it safe to assume that the expansion tanks don't fail as often as some MX-5 owners would have us believe? I'd change mine for one of the "recommended" alloy or stainless replacement tanks. But at £100 ish I'd rather put that money towards performance upgrades.
Good Morning, many thanks for the comment. I’m a big believer in if it isn’t broken don’t fix it! However I do keep my eye on it and it’s still currently in a good condition it’s just yellowed over time. I like the look of the metal/alloy tanks but in practical terms you can’t see the coolant inside if the engine is hot. When and if mine does break I’ll just get a replacement OEM one because I know it’s designed to take the coolant, it’ll last at least another 10/15 years or longer . In fact it will outlast the rest of the car! I can’t say the same for the alloy ones, and if the alloy degrades internally where does the alloy go? I hope that helps
Hi Sorry for the delay in responding, it’s advised not to play with it, however moving the flap will not affect the performance of the TB. It’s advisable to clean underneath it do that it gets a good seal.
@@jackos5s So I ended up cleaning it along with the MAF sensor and the before and after photos are just astonishing after 140K miles. Now when I am in gear the car will steadily roll forward without me having to apply any throttle. I always thought it is normal for the car to choke up and almost stall in first gear if you don't give it gas but boy was I wrong. WORLD of difference the cleaning made (at least in my case).. Thank you for the reply and more so the video, really helped me out. My car can finally breathe now!
Absolutely brilliant, and by doing this you’ve probably saved some big bucks in fuelling alone never mind the internal damage /wear and tear that’s caused by clogged up TB.
@@kevinincollege Can't speak much on the MAF just because it is more difficult to see, although my car had a KN filter when I bought it and the oil from those filters are known to dirty up MAF sensors more than traditional paper filters. Now as for the throttle body, YES that things was totally filthy. I have a good feeling that after 140,000 miles I was probably the first to ever clean it, hence the amazing results. 😃👍

Thanks for the video. I recently got an intake manifold, and I've been trying to find a proper way to install it. Your video's been very helpful.

Thanks for the great video.I now have the courage to clean mine.From Rochester,NY USA. Where are you located?
Hi William, that’s great news to hear. I’m from North Lincolnshire, Uk 🇬🇧 thank you for the comment
What a great video, wish they were all like this... I'm about to clean mine, do I really need a new throttle body seal?
Hi Buddy sorry for the delay, thank you for the feedback. You should really get a new sale. However if the old one is good enough stick it back on you’ll be okay and you’ll save a few pound as well.
what did you use to clean the outside (Aluminum) case with...?
Here in the USA we use CRC T.B. and MAF cleaner
Thanx for the video.

Thanks for sharing! This is very helpful! 🙏🏼
Glad it was helpful!
Great vid, thanks. Will give it a try after shopping for all the tools I don't have. FYI gasket £17.58 on MX5parts
Lol 😂 just grab a few tools from eBay to sort you out. Really pleased people are finding the seals cheaper and cheaper
need a vidio on how to get the air out of cooling system after any cooling system repair

I have seen on the FB page for MX5 NC you can use Ford RS throttle body seal for £4. Would be keen to find it online.
That’s interesting to know, if you find out for definite I’ll share across the platforms👍👍
When I uncorked the top line a lot of coolant squirter out
Don’t worry about it, just make sure that the coolant is at the right level when you finish up👍👍

Is it ok to push open the butterfly when its off
The “experts” will tell you not to, however as long as you don’t mess around too much they’ll be fine. You’ll need to move them to clean around them👍
Why do they say not to push open electrically operated throttle bodies? Can that actually damage the throttle body?

Is this a 2.0 or 1.8? Any idea if there's much difference?
Hi Buddy, mines the 2.0 but the 1.8 is exactly the same 👍 good luck
My NC idles high and got the code p0507 after I cleaned the TB. Do you know what might have cause this?
Thank you for the videos BTW!
P0507 MAZDA Possible Causes
Dirty throttle body
Electric throttle control actuator misadjusted or damaged
Faulty Electric throttle control actuator
Intake air leak
Poor electrical connection to the Intake Air Control (IAC) valve
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Or just clear the code and see if it comes back
Thank you for your comments and watching
I watched somewhere that there is a thin coating that should not be removed, if removed the throttle diaphragm will not seal throttle body causing high idle
hey, where i found a seal ? amazon its empty :
Sorry buddy the company stopped selling them
I don't know why i'me watching this. I don't even drive.
Lol 😂 one day you might tho
