Props buddy for making this whole video with that fly never letting up and not losing your cool.

Besides having an actual evaporative emissions class, like I have for multiple manufacturers, this is probably the most comprehensive vid on this. If your canister is cracked or a hose is cracked ,you usually end up with a p0456 code, gas cap or large failure is a p0455 code.

Maybe you can post the extra footage where you show that fly an alternative use for the charcoal canister. lol. Nice job keeping your cool with that constant distraction! I'll second another comment that a video on the EGR system would be interesting. Thanks for the informative content!

Great job despite your winged fan!

Good stuff, learning as fast as my old brain will allow.

Sorry Mike, couldn't take my eyes off your new little friend 🪰, 😆

I love the videos, you guys have helped tremendously with issues i run across on my 91. The playback volume is k8nd of on the low side though. Like you're standing juuuust a little too far from the 🎤

I didn't know there would be Ron spoilers!

19:49 if you have an OBD2 Miata to get rid of smells notice if you unplugged the battery. If you did, get a code scanner and check your OBD2 system and perform a drive cycle.

Can confirm the NBs get cracks on the bottom where they are sealed together. They are totally empty FYI and don't contain charcoal. I'm just going to replace it with a catch can full of charcoal because I'm tired of the fumes after driving

hmmm....did i miss the episode where you installed the coolant tank overflow? I have been wanting one of those a long time now, will be ordering one from you guys soon

I knew most of what you described, but what I'm interested in knowing more in depth, is what is the computer logistic timing of opening the solenoid and under what conditions does it cycle? What did you all do to your LS 3, V8 conversion since it was fitted with a different operating system? I'm also a firm believer in keeping the EVAP canister function. Plus, you didn't mentioned that if the fumes are just allowed to freely escape when the EVAP circuit is removed, then in the hot sun you're just wasting gasoline through evaporation. Good video, but I'd like to know how the Habu conversion's EVAP was handled. Thanks

Timely video, since on my 1999 I have a check engine light and a gas vapor odor in the trunk area. I've replaced the gas cap already, what other components at the rear of the car should I be checking? I recall seeing some other valves and another charcoal canister on a parts diagram but I can't find that now.

Nice to know how it works but I’ll still be removing mine as it’s old and worn out and I actually partially like the smell of the vapors, reminds me of my childhood spent riding old dirt bikes and atv’s around, they had a little smell but it was just part of the experience to me. once your moving you can’t smell anything anymore so it’s really not a problem unless you just hate the smell 😂

My two cents: In an EVAP system, the activated carbon does not absorb fuel vapors in the same way it might absorb odors or contaminants in other applications. Instead, the activated carbon provides a large surface area for the fuel vapors to condense onto, called adsorption. Adsorption is a surface process that transfers molecules from a liquid or gas to a solid surface. The molecules that are transferred are called adsorbates, and the solid surface that attracts them is called the adsorbent. The reverse process of adsorption is called desorption. Think of it as a solid phase vapor condenser using adsorption.

I have an odd Miata question. Is there a way to get replacement evap information stickers like under the hood?

I sometimes smell gasoline in the cabin, but only after several hours of highway driving. I've replaced the fuel pump and the rubber seal around the fuel pump assembly. I don't smell anything in the trunk. Wondering if it's the evap system.

I have a NB2 miata with additional charcoal canister and two other plastic containers in the passenger rear wheel well (next to fuel filter). What are those? I've been getting a fuel smell in cabin and it does seem to smell on that side. I replaced the shoe-box-shaped charcoal canister and then I noticed a solenoid-looking thing next to it and another, smaller cylinder "can" next to that all connected in some way to the charcoal canister. Again, none of this is engine bay. What are those and how can I test/clean them to see if they aren't purging the vapors correctly (eg causing smell in cabin)? I assume that trio in the passenger rear wheel well eventually push the vapors to the engine bay's canister and solenoid?

Does an aftermarket ECU take that selenoid operation in charge?

7:51 current problem on my NB2

There’s a decent amount of vacuum pressure released when i open my gas cap after driving my 1990. Is this a problem?

could this be where my mystery fuel smell is coming from on my 99 nb? ...although id swear it smells like its coming from the trunk area... always enjoy yalls videos, thank u

I Have a 1999 Miata with a P1450 code I replaced the Vapor Canister Purge Solenoid and Vapor Canister Vent Valve, with no luck some times think I smell gas?. engine runs rough, bogs on fast pedal acceleration. Under the rear of the car looks like the square charcoal canister if that's the only one I don't know It don't look damaged. "I need help"

Great video, thank you. Would love to see a video on the EGR system similar to what you did here. Also, you mentioned posting the names of some salvage companies you could get some used evap. components from. Can you post links for those companies?

What about smells inside the car with the top up ?

🪰

Its pretty ridiculous that they dont design them to be serviceable. I cringe thinking about not changing aquarium charcoal, let alone 30 year old fuel saturated charcoal. What kind of drivability issues can a bad solenoid cause or leak in the system other than a CEL? My doesn't even work. I mean the light itself comes on at start as it should but I cant get it to toss anything after that. 😂 Someone would make bank if they made anodized serviceable ones.

I have several if anyone wants to give me money for them.......after I remove the slack from the throttle cable, then next thing I always do is remove the canister and loop the hose. No one is going to come after you for removing an item that no longer works and replacements are no longer available, remove it, free up access room to the oil filter, and the alternator throw it away and sleep like a baby. I do and so can you.

that fly is very distracting lol

I really dislike climate activists, Ive heard every fairytale they can think of for 55 years and NONE of the fear porn has come true lol Thanks for the video, this is a good explanation about what to me is the ugliest piece of gear under the hood haha
