Hmmmm, interesting, yes!
More video, maybe just one from different angles, now, with the plug deeper in?
Yeah, Ian, that can be extremely important, what depth the plug tip is getting into the hole. I had that problem with another 22re, but it didn't cause a miss.(NOT saying that isn't some of your cause, ....clearly you said you feel an improved difference, eh?).
Only thing I was gonna say, after listening/prodding/multi-metering/stethoscoping/open heart surgery'ing this thing for a year now, ahhahahaa.... Well, was gonna say, I can't be sure, but it almost sounds like an injector is intermittently not firing. I hear that fast click, in the second video, ...then seems to be pausing in it. Anyway, easy check, just put a scope to it and listen in, eh? if you don't hear them cutting out on rare occasions, ....probably not related. Could just be other noises filtering out the injector sound, etc., ya know?
Also, not to freak ya, cuz it most likely means nothing, ...I almost feel like I hear a slapping in that same video, more toward the end, when you're on the exhaust side. I'll listen again and tell you what time in the video, ..hold on, hahaha....
Ok, video 2, 54Seconds, through to the end. Could just be something rattling/vibrating. Just thought, can't hurt to put a scope to the cover, too, eh? And again, NOT saying anything, just hard to diagnose by video/audio, ya know? lol. BTW, I LOVE that tool, the stethoscope! lol.

I hear ya, ..... it feels good to look at it when it's done and listen and drive it, etc., etc. Knowing you saved a gaggle! Woot! lol. However, I've been at this thing for a straight year..... I think once I'm done with the suspension re-do/lift and AC, ....I'M DONE-DIGGITY-DONE for a while, ....ya know? hahaha.

Hahaha, ...yeah, I hear ya. I've been looking for a while. I want an 85 Xtra CAB 4wd SR5 with EFI, ...Or long bed, same dealio otherwise. I know it would be a project because I can't afford the super clean ones! lol. However, once I get said new project, ....I wouldn't be 'just driving' my other one that's fixed much, would I? hahaha. Meh..... s'all good, I'll just be grateful to have this one running and, well, 'RUN IT' for now! lol.

hahaha)Also thinking of finding an 84+ Cressida. .... The one I had was REALLY quick and INDESTRUCTIBLE! That straight 6 was a SWEET motor! Mine had a Z-Series Motor(think that's what my buddy the Mechanic said, lol)... it was a Japanese Performance Version, and was VERY quick! (Also to have something easier to pick up mom with! lol)
Ok, sorry for the tangent there, Ian!

ok, so i had a thought: swap in a 22r and run propane/gas combo, or just propane. i know it sounds crazy, but i'm seriously looking into it. i have a few questions that might be better asked on yt than other sources. i searched around a bit, and the list below is the things i'm not too sure about
(for simplicity, i am only talking about late-model 22r's)
--22re to 22r. it seems the only differences are: distributer, coil, throttle cable, and upper/lower intake manifold
--ecu no longer required
--would i need to change the fuel system? or could i still use the same electric fuel pump, tank, and lines
the list only applies if i want to do dual-fuel. it looks like it'll be cheaper just to go propane-only. i can also apply for tax breaks and free rides in the hov lanes
any input, let me know what i'm mistaken on, etc...

Fuel pump on 22r is mechanical.
i would think a multi-fuel vehicle would be better suited using a programmable ecu like the MegaSquirt. You could dial up a fuel map depending on fuel type/mix for better efficiency.
I have no experience with any of this stuff. If it were me, i'd go diesel/bio-fuel....or 1UZ for the hot-rod effect.

you'd have to change fuel systems as well. No way to safely regulate the fuel pressure from EFI down to Carb. Not sure if there is a drop in replacement for the fuel pump so a fuel tank change might have to be done. Lines should be fine though.

thanks guys
i also read that the 22re block has a place for the mechanical fuel pump, but it has a block-off plate... i dunno, but i might be able to put one in.
the reason i started thinking about this was the recent spike in gas prices, where i'm paying as much for regular as premium used to cost. i did the math, and if i commute with only propane, it should pay for itself in 5 months (fairly quick turn-around in my books). the efi-propane kit costs $850, and the dual-fuel is $950, but i'd have to change to a 22r set-up, which would cost more in total (more than just $100 extra)
correction: lce sells the efi kits for $826
another search yields more info. looking at parts diagrams (22r and 22r-e), it looks like the intake manifolds are the same bolt/hole pattern. and i can get a 22r manifold for less than $100 from a junkyard. also, lce lists the head and cam as the same for oem replacements on 22r & 22r-e

The fuel pump is on the head, not the block. And yes there is a block off plate. I think you would need to change the cam pulley since that is where the arm for the pump rides.

The head does have a block off plate. You don't need to change the gear there is just a fuel pump eccentric that goes between the cam/dizzy gear and the timing gear. When I did the engine replacement in my truck the engine was set up for EFI. Its really easy to do just undo the cam gear, remove the spacer btwn cam gear and timing gear, slap the eccentric on, install the cam gear and torque. Then install the fuel pump. Takes only minutes. As for the propane, I have no idea of it but have been thinking about it myself.

thanks zach. yeah, i've been looking at the diagrams on toyotapartszone.com, and now know there's a bit more than just a manifold swap. people who say they've done it really like it. i want to do dual-fuel so i don't get stranded (being my dd and all)
another neat idea would be to put a regular cab on my frame. might give me the space i need behind the cab, while keeping the bed intact. probably won't do it, though (yet, haha...)

as far as the 22r mechanical fuel pump, not needed, just use an electric. but if you do wire it right and use a oil pressure cutoff switch. This way if something happens to the fuel line ie crash and the key is on the fuel pump doesn't still run when the engine is off.

hmmm... sounds good to me. do you have a reference for said oil pressure cutoff switch? do they come in different values or adjustable? i'll be searching, as well.
and what do you mean "wire it right"? just so it's on when the ignition is on?
that would make the swap soooo much easier if i could leave the stock tank, lines, and pump
