Agreed. I can't stand those dudes that just talk to talk. It's like watching a "how to video" presented by a woman. Makes me want to slam my head in a car door 156 times.

And Money to spend.

Hahaha, good one!

So true. I was scratching my head for a while on this one. The service manual, of course, calls this a non-servicable part so stuff like that can throw you for a loop too.

Finding a good condition with one or two owners tends to be key. A lot of times it's people modifying and hacking stuff up that tends to make some problems hard to fix. There is also a ton of support and passionate people that love these old Toyotas. Forums can be hit or miss but I like Marlin Crawler and Yotatech they should help if of you ever need it.

Hola amigo sadulo desde chile

No problem, hope it helps!

From lots of trial and error haha. Thanks for watching, hope the vids are helpful!

Aside from the body about to rust away from the frame not much lol

Que problema tenía tu camioneta yo soy de chile y tengo una 1993

@@nicolassanmartin1777 hola, en principio paso agua a las cabezas, por lo que la repare y pues en este proceso el sistema de escape estaba saturado de sedimentos del anticongelante por lo que la limpie pero mucho de este quedo en el sistema de escape y al ya arrancarlo cuando quedo reparado por primera vez saco todo por el mofle, mi camioneta no tiene catalizador por loq ue saco todo sin problema pero si hecho mucho humo y despues de unos minutos dejo de hacerlo y todo quedo bien.

Same thing with me too and same year 2wd 93

Check the comments on this video. Another viewer had the same issue and made a video on how they went about getting it to move.

Thank you. For others looking here is the tool you can make to free up the iac valve. kzfaq.infovh7fkhvqq0c?feature=share

@@theblizzardof78blog did you get yours out I've made 3 sockets and let it soak and it won't move

@@coop_69 hey no i never did, never made a socket. I Ended up replacing the throttle body gasket and that helped. I also saw that my rubber air intake had cracks in it and replacing that helped as well.

Not much more. I only have one more video planned on the 4Runner.

Whatever it is, I’m looking forward to seeing it

I did everything to it , hammer, impact wrench, heat, nothing has worked, I'll keep in trying an let you know, greetings from Quetzaltenango 🇬🇹.

Did you happen to find a fix for this? I’m having the same issue.

I finally got it out , heat the pice with a heat gun and then use a wrench socket (home made tool) and will came out.

Hola amigo te saludo desde chile yo tengo una Toyota 4 runner 1993 motor 3vze con unos problemas en el encendido quisas me puedes dar unos concejos

What tool did you make

The more you unscrew it, the higher your cold start idle speed will be. Unless you live where it freezes I;d screw it in like he suggests.

@@supercharged2414 there is something wrong with mine, nothing worked at all. I believe it was my injectors.

@@Zapp760 Does the idle adjust screw change the idle speed?

Not on this 4Runner, but I have on a pickup with the 3VZE. I'd recommend adjusting it if the engine idle "hunts" when you press the brake at idle.

@@PracticalEnthusiast I just did the heads on my 94 4runner and replaced parts along the way...including the TPS. I pretty much set it in the middle. It doesn't "hunt" when I push on the brake. From what I gather, the TPS has to be set prior to timing it, and I am having no luck in finding a video in how to do so. No explanation in my Haynes either. Thank you for your quick reply and thank you for taking the time!

No, I never experienced that noise. Did you clean the valve at all? It's possible there's some sort of build up on it allowing air to get by and make that sort of noise. Don't know what else it could be if it's coming from the throttle body.

Good point. Definitely want to check those too.

I didn't rebuild the engine for a few practical reasons. 1) I didn't have the time. Removing an engine, disassembling it, videoing the process, editing that video, getting parts, waiting on the machine shop, reassembly, reinstallation, takes a mountain of time. 2) I didn't have the space. Removing an engine means you need to have space for the engine crane, an engine, a transmission, etc. all while being in the middle of a cold, snowy winter when other cars can better use the garage space (i.e. my wife's car and my Z) 3) Cost is relatively minimal, so it's definitely not a large contributing factor to the decision 4) The engine, quite honestly, didn't NEED the bottom end rebuilt. It worked great until the head gasket blew, which is a independent issue from the bottom end. When you're dealing with older cars, you can easily make a case for rebuilding/replacing everything that looks mildly worn. This is why you see so many vehicle projects become never finished, forgotten, and ultimately sold for scrap. You have to have your practical limits. This is why the engine was not rebuilt, and this is why the truck runs and drives great right now, not months or years from now.

I haven't heard that one before. Hmm. I suppose it could be this, but I'd first check to make sure the butterfly valve or the throttle cable isn't binding somewhere.

No part of this assembly is replaceable, aside from potentially the entire throttle body that Toyota may or may not still make (going to be a lot of $$$$ regardless). Screwing the valve in deeper is the correct fix here.

This would only help if you're experiencing low idle during a cold start. Interesting that the idle adjustment screw doesn't have any affect at raising the idle speed. I would check the simple stuff first, like the air filter, to make sure it isn't clogged. Then I would check for vacuum leaks because those can sometimes cause a rough and lower idle.

It's dependent on engine temperature, but at 75 degrees I wouldn't think it would trigger a fast idle. Even in freezing temps it wouldn't be more than 5 minutes at idle. If diving, it would be much faster.

@@PracticalEnthusiast Thanks for the information.The engine cold start,, summer are winter will consistently run fast idle for 5 minutes and then go to idle 800 RPM. Perhaps the throttle body is the culprit.

@@patalexander1965 I'd say it's definitely in the throttle body. However the issue is likely different than shown in this video since yours does eventually drop to 800 RPM. I'd check that coolant is properly circulating though the throttle body. Could be a blockage or air in the system.

@@PracticalEnthusiast Thank you for this information. Will check soon.

I don't believe they are available, but you can use RTV to seal it up.

You can't get the gaskets anymore but you could make one out of gasket material, or just smear some RTV on there.

It should be completely closed when the engine is warm, but I couldn't tell you what temperature that is.

That's a tough one. The idle control on this engine is fairly rudimentary and I don't think it has any idle-up system to account for an automatic transmission being put into drive or any other gear. That makes me suspect that something may be wrong with the torque converter. It might be partially or fully locking up when put into drive, causing the engine to die.

Does it surge only when the brake is depressed? If so, it is likely your throttle position sensor is out of adjustment.

My 88’ 4Runner surges at random too. Took throttle body off and cleaned it. Ran the codes for the check engine light and it shows “TPS” so gonna change that next. It’ll surge when I push the brake it but some times does it even with the brake not engaged, still could be tps? Or anything else?

Unfortunately Toyota doesn't sell the valve separately from the throttle body. You would have to buy the entire assembly.

You could!

The surging idle is likely a mis-adjusted throttle position sensor. I'd start there.

Check the comments. A few have also had difficulty removing the threaded collar and one commenter made a video of a tool he made to remove it.

I would check your ignition timing at the distributor. Could be the ignition coil as well.

Not available. Use silicone or make a gasket.

You may have lower oil pressure as a result. Not worth the risk of pressure loss.

Yep, an IAC could definitely cause that. Or, the engine temperature sensor could be at fault. This is the sensor that tells the ECU the engine temp, not the one that controls the temperature gauge.

@@PracticalEnthusiast Thanks for the reply! I've already swapped out the coolant temperature sensor as that was my initial suspicion. Guess I'll have a look at the IAC next.

I never swapped it, so I'm not sure what's up there. Sure it wasn't used on early 3VZEs as well? This one is a first year (1988).

Yes i do. Screw the adjustment collar a few theads farther in. The farther in you screw it the lower your HIGH idle will be. Clean it thouroughly before reassembling it.

Yes

They are not available. I wish it was replaceable. The whole throttle body isn't even available anymore.
