Just ran across your video. great explanation. My 1997 4runner was idling at 1,900-2,100 rpm hot. Pulled the TB and IAC and the valve was stuck and the coolant passway was completely clogged. Cleaned the IAC valve and coolant reassembled. Now idles at 700 RPM. You saved me at least $300. Thanks man!!

Excellent and very informative video! Great info on the "stripping" issue, as I nearly stripped one of the IAC bolts on my '99 4Runner. Come to find out that these bolts are not Phillips but rather JIS (Japanese Industrial Standard), aka "Japanese Phillips," which apparently have a more squared-off cross-shaped indentation than Phillips, hence, the tendency to strip when using a Phillips screwdriver. I took your advice on got the hex bolts! Thank you so much for the awesome video!!!

Great video my dude. The proper name for the value you are referring to is called a butterfly flap. 🦋 because it is a disc shaped flap with a center pivot to regulate air flow better.

@JohnnyTrulove Жыл бұрын

I'll need to try this. Going to clean the IAC before to see if it solves the issue before going and buying a new OEM one.

Excellent video. Did the job today and, even with not having my tools ready, it only took an hour and a half. But, you certainly freaked me out about those damned Japanese Phillips screws!! I was EXTRA careful when I was removing them. But, after the first one got free, the thought crossed my mind, "Hey, I've been dealing with Japanese type screws my whole life! Why was I freaking out?" I had Japanese dirt bikes when I was a kid (a measly 55+ years ago), so lots of metric and Japanese Phillips screw. I didn't even know there was such a thing as a Japanese Phillips screw until today when I watched your video. Anyway, good job on the video!

Hey, my 02 4runner has been idling at 500 rpm’s and is very shaky in reverse and drive while at a stop. I removed my throttle body but it does not have an IAC valve. It appears to be a 02-04 tundra throttle body. Any idea what I can do or what it could be?

Need advice. I've replaced fuel filter check Purge valves mass flow sensors and I'm still having a stalling out issue the only thing I haven't replaced is the IAC valve that I just ordered most likely need some reassurance that I might finally get it?

@cf6979 Жыл бұрын

Hi Victor, did you figure it out? Hopefully you did since it's been awhile since your comment. If it's been awhile since last tune-up, always easy to replace spark plugs, clean mass air flow sensor, air filter, and check for any vacuum hoses for leaks too. My hoses are cracking and need replace soon.

@neilnarciso4945 Жыл бұрын

I was replacing the leaking valve cover gaskets on my T100 and tried to remove the screws on the IAC valve but they were just too tight. PB Blaster didn't help at all. Did you use a JSI screwdriver? Also, what are the exact dimensions of the stainless steel bolts that you replaced them with? Did you get them at Home Depot or Lowe's?

@PartimeOverland Жыл бұрын

If they're too tight you can always notch out the heads with a Dremel and use a flat-head. I got the new bolts at a local hardware store. As long as you bring in the old screws to match up the threading you should be good to go

My third gen Toy idled around 1500 in park, after I replaced the IAC. Just put in a new TPS and the bitch jumped to 2200 after a few minutes. Difficult to get her to start again. Guessing I have to recalibrate these sensors through driving, like you mentioned in final thoughts. I don't have a scanner... How long do you have to drive it before it programs? I'm afraid that the idle is too high to be driving around, but I don't want to manually adjust it just yet.

@PartimeOverland Жыл бұрын

So a few things here. First check to make sure you didn’t somehow dislodge the throttle cable. I did it once where the throttle cable was stuck around the wheel and it idles high. Assuming that’s not the case, try disconnecting the battery for a few minutes (the longer the better honestly). This will reset the computers so they learn from scratch, rather from your past settings…

@2028end 3 ай бұрын

@@PartimeOverland I have this same problem. I cleaned my throttle body and IAC valve and now have 1500 idle in park and neutral, and 1000 idle in drive while stopped. I had the battery disconnected the entire time I did the cleaning job, wouldn't that be sufficient so that it would learn from new? Or, is this an ECM problem? The ECM still retains the old information even if the battery is disconnected? I'm thinking we might need to be pulling the ECM fuse, or something? To reset it? Because I've been driving my truck for 4 days now since doing the cleaning, and it's still idling just as high in park and neutral. That's why the guy above asked, HOW LONG do we need to drive the truck until the ECM starts resetting the IAC valve bringing the idle down in park and neutral? Is is a week? 2 weeks? a month?
