    Re: Won't idle when cold

    The one on eBay was an auction and was at around $30-40 when i bid on it with 30 seconds left. I bid it all the way up to $120-130 and still couldn't secure the max bid before the auction ended. I think someone had already set a really high max bid or had a bidding bot.... anyway it ended up going for almost $160. Not too bad I suppose for being probably the last brand new part in existence, but still more than I was wiling to pay, lol.

    the hose won't fit those bends - I'm battling that issue right now. it kinks up badly. let me know how you end up figuring it out!

    my aux valve MIGHT be okay, since i don't have to play the e-brake/gas game at stops like you do. it only happens on the initial warm up in winter. Even then it usually manages to stay just high enough to idle without dying, but it takes it a while to warm up as a result (unless i give it a little help, lol)

    Re: Won't idle when cold

    Lol, I had a snipe bid of $150.01 on it. The snipe site I use is supposed to go max bid within the last 7 or 8 seconds of the auction. When I set my max price there was 7 hrs left with 2 bids and price was at ~$26. When I got home that night I was actually surprised to learn I wasn't the winner . I guess I screwed up earlier by telling somebody to go search eBay for one. Lol. Tim

    Re: Won't idle when cold

    LOL, yup it was me that won that eBay auction. I figured anyone else that wanted it was probably on this forum but I didn't realize the competition was so fierce! I actually placed my bid before I saw this thread, so you can't blame me for whipping up the frenzy! My max bid was Toyota's original retail price since I figured that's what I would have had to pay if it was still available, and if I didn't get it I wasn't sure what I would do. I actually thought about bidding way more just to make sure! Obviously I need to get more high tech to ward off the snipers! It gets cold here in SLC so I'm excited to have a van that idles in the winter.
    I got a few shaped hoses from the local auto parts store that should work. One is a 1/2" hose which is a bit snug but should get the job done.

    Re: Won't idle when cold

    This guy on eBay still has 2 left http://www.ebay.com/itm/Fuel-Injecti...JZJcHF&vxp=mtr, but I just can't bring myself to pay $285 for one. I would go $150, but any more, I'd rather take my chances with a good used one (I still have a few of those laying around). Glad I got all the molded rubber hoses when I did (now that they're like hen's teeth). It's a bummer when these type parts become NLA. I really wish I would have purchased a few more sets back when you could still get them. Tim

    Re: Won't idle when cold

    If that part was easier to get to I might have tried a junk yard one. The Dayco 80393 hose cut to fit will work to replace the NLA hoses (22233-73010, 22236-73011, 22237-73010), it's a bit snug (1/2" vs the 14 mm nipples). It's about a third of the price at Rockauto than my LPS, wish I'd found it there first:

    Re: Won't idle when cold

    Awesome! This is exactly the kind of information that makes forums worth while. FWIW, i thought these were 14mm, but didn't have one handy to measure. For vacuum, being a bit snug is better than being loose (no hose clamps needed). I just purchased a few of those for future projects. Tim

    Oops! I mentioned the standard to metric difference in a different thread where this topic was recently discussed but incorrectly said they were 12mm. My only issue with the stretch fit was out of concern that they may split as they dry out and shrink from the heat. Of course I had alternate options at the dealer several years ago when I did my HG. I suppose it's a moo point now.

    Re: Won't idle when cold

    Oh man, thanks Hammervan! I was about to just put the OEM's back on and try my luck. They were in decent shape but definitely older. I just ordered 3 sections of the Dayco 80393 hose that you linked to replace the 3 sections with the sharp bends.

    BTW im in SLC too, so I'm going to hunt you down for taking my aux air valve

    Re: Won't idle when cold

    Oh man, when my aux air valve suddenly disappears from my van, I'll know who took it, mistershmi! I'll keep my eyes peeled for your van, I see a few still running around Salt Lake but they all seem to be 2WD. Glad the hose info was helpful.
    Of course, now that I've replaced the hoses on the aux. air valve, including the 8 mm coolant hose, I've now noticed Tim's mention in another thread that it's best to use the original Toyota spring clamps and genuine Toyota hose for the coolant line. I used the same 5/16 fuel line hose and regular hose clamps like I did on my Hose of Death. Not sure if it's worth putting the original hose back on before I put it all together...

    Just a heads up. I just tried to buy one of these with some expendable cash I had, to save myself tracking one down later if the part ever fails on my van, and they had to refund my money. They don't actually have them in stock and had to go to the dealer where they learned they were NLA. Said he would be removing the auction listing.

    Re: Won't idle when cold

    Back when I used to sell there eBay required sellers to have physical possession of items before listing them. I guess that must have changed. I've purchased things from eBay before only to receive things drop-shipped from other locations. Next time I needed them I went right to the company who drop shipped and saved some money. I guess there's nothing wrong with sellers doing that as long as item arrives in a timely manner........just seems a bit fishy though. Glad you got your money back. Tim

    PS: Funny how van parts just disappear from existence without warning. With the prices Toyota was asking I figured they'd be around for a long time. Tim

You used to be able to get aftermarket ones off rockauto until just a year or so ago, but it appears now they are gone. Even those were expensive........just not as bad as OE.

    The symptom of a bad one is having correct idle speed when cold but high idle when hot (if it's stuck open) -OR- having a low idle speed when cold, but a correct idle speed when hot (if it's stuck closed).
    Hi Tim,

    Is there a thread detailing the least painful way of removing/installing an idle air control valve? Mine is bad and I'm going to try to get one off a parts van this afternoon. Any help would be greatly appreciate.

    Thanks!

    Re: Won't idle when cold

    Sorry, no magic bullet here. That valve is actually bolted to the underside of the top half of the intake, so it has to come off before you can remove the air valve. Here it is in all it's glory:

    Thanks Tim,

    The only description in the FSM that discusses access to this area is for a cylinder head removal, which includes opening the full engine compartment, draining the oil and coolant, and removing the exhaust pipe, throttle body, power steering pump, etc. Do you recall if all of that is necessary to access the idle air control valve?

    Also, I found this while searching the web for the NLA part:

    https://www.rockauto.com/en/catalog/...ac)+valve,6072

    The part numbers don't match, but it says it's compatible with our vans. And it's cheap! Probably too cheap. There's only one left. Thoughts?

    Re: Won't idle when cold

    That's not the air valve. There's a discrepancy regarding the aftermarket part manufacturers terminology vs Toyota's. We call that part the AC Idle-up Diaphragm. To find out more about it CLICK HERE and scroll down to the middle of the page.

    You don't need to remove the cylinder head to remove the air valve. You just need to remove the top half of the intake manifold. Of course that's not quite as easy as it might sound. There's a lot of other little things that need to be removed before you can do that. You might want to read the Hose of Death thread and cut an access hole in the back of the engine hump (as shown there). Having that access hole is an enormous help when removing the metal pipes from the back of the upper intake. Search the site for for more information on the other steps. Threads that discuss head gasket jobs should mention steps for removal of the upper intake. The information is here, the trick is finding it. If you're not having luck with the site search feature, use Google or other similar search engine (as talked about HERE). Tim

    Re: Won't idle when cold

    Absolutely not a problem . BTW, just thought I'd mention that AC Idle-up diaphragm is one of the few parts you can purchase from Toyota that's cheaper than aftermarket off of rockauto. Last time I needed one I found it on ToyotaPartsDeal.com for $17.86 (I purchased 4 of them ). Tim

    Re: Won't idle when cold

    wow this has been a great read for me. my poor van has been sitting for close to a year meaning I haven't used it much because I have a new job and don't use the van much. after reading the symtoms I believe my air vale is not working as it should. as usual Tim and the rest have help enormously with facts and pics.. thanx for that all. I spect I have a few bumping around in some Tupperware boxes and will replace it with one. I looked at what I thought will be an attack angle meaning I already have cut out a window in the firewall(hump) and should make this repair a bit easier. now just to be clear when I do start the van it runs just fine for maybe a minute then drops to idle then it just stumbles and rumbles and shakes after it does come to temp it runs kinda normal. think ill wait for a bit warmer weather and some extra time...did I mention its gonna snow here in Rhode Island this week! calendar says spring but I think thats a misprint
