I have watched numerous videos on cleaning out the IAC valve. My Matrix's idle was erratic and getting higher by the hour reaching 2,100 RPM at the outset. I did not relish removing the TB then removing the IAC from the bottom of the TB to clean both thoroughly. Most videos on YT suggest removing all and cleaning on your bench, then reassembling. Certainly a bench cleaning will guarantee that most carbon build up will be eliminated, but I have screwed up projects before by doing more than was necessary. I followed your advice and saturated that rectangular opening in the TB and allowed it to penetrate the carbon. About 30 minutes later, I put the few parts back together, started the car and let it warm up. I put my tools away, then checked again by revving the engine and seeing the RPM settle at 900 RPM. Bravo, all works well! Thank you.
You got a like from me! It worked! Talking about being at a red light and the car is idling like it's ready to jerk as soon as you release the brake. Then having high idling as soon as you start the engine.
@ApplePie 2019 No doubt the repair shops try to soak you. I'm suspicious they charge my daughter more than the book rate. They wanted $250 for cap, rotor, wires and spark plugs. I spend $75 for the top quality stuff and 20 minutes to do the work. And it wasn't even hard!
Dude that shit worked!!! But u don't have to wait a few min or hours after spray. Just hit the gas when turning the car on and leave it pressing for 10 sec. And let go of the gas and it stays on. Thanks for the info.
Don't let a mechanic replace the IAC valve without trying cleaning it yourself first. The new valve is over $200 ! If you don't have the hose that connects to the crankcase don't attempt to clean the IAC while it's on the engine. All the cleaner and chunks of carbon will be sucked right into the motor the first time you start the engine. Take the throttle body off the engine first. I rebuilt my niece's 2001 Camry's 2.2L engine. The car had been sitting dead for over 2 years. After the rebuild the engine ran great, but idled too fast once warm. I found the IAC had locked up with carbon AND the motor's windings were open. (I should have checked that all out during the rebuild.) There are 3 terminals to the IAC motor. Measuring the resistance between the middle and either of the outer terminals should result between 16 and 23 ohms (depending on the application). Mine were 56k one side and completely open on the other. I'm off the the junkyard !
This is a waste of time... Disconnect the middle hose in the IAC that connects to the crankcase.. put a can or a bottle to catch the cleaner/chunks etc.. clean out carbon in throttle body and iac then Easy fix.
I just cleaned mine and because the idle air control valve motion is so sensitive it must be removed and cleaned with wd-40 and throttle body cleaner with a toothbrush and you will need a new idle air control valve gasket to put on too. Pretty east. Also clean your throttle body with the same stuff while it’s right there. The crud only goes away from the iac after you wipe it clean no soaking will make it very clean. Promise. When you’re done scrubbing the iac use brake cleaner to clean the junk out. Peace.
The 98 Camry LE 2.2 liter has three hoses and an electrical connection on the California model and two on the reg fed. The inside one connects to the crankcase and the other two to the coolant flow I believe.
@@jackhawkins4056 you are correct, mine only has two hoses for coolant and no crankcase hose, if it has the crankcase hose I would d/c it because you don't want cleaner going into crankcase. Thanks for post, I was wonder why mine only has two hoses.

Wipe out the large diameter tube with a rag/cleaner and do NOT let cleaned liquid debris go into the square hole that leads into the IACV.... all those contaminants will gum up the rotating valve in the IACV. To direct spray into the small Throttle Body opening to clean the IAC valve drains the fluid and carbon into the intake of the engine
Imma try this!! Good slow easy video for someone who don't got more money to keep paying shops for "fixin my problem to continue to keep having the same problem after I pay a shyt ton.. Mine shuts off as soon a I turn it on now. Unless I keep foot on the gas!! Before this stage. It would idle high and then so low I thought it was fixin to shut off!!! I Also saved a great vido on how to change the idle control valve.. hoping I don't total my car!!! Imma go into this, with how to videos, and the mentality that of I can build some crazy shyt without the instructions packet, I can do this with how to videos!!!
My 1998 toyota camry 336k is high idling while parked and the ac on lately has sputtered and shut off twice while parked and ac on, not sure if this will help but I’ll try it out before taking it to a mechanic! Thanks
The issue I'm having is not quite like this period my 2000 Camry ( With 453 K miles) Has had an ongoing issue literally for the past 15 years or so where where shortly shortly after start up start up the idol feels really low. Although she never feels like she's going to stall she does this annoying it's annoying almost galloping thing. She quickly comes out of it if you either rev the engine the engine for about 2 seconds or turn on the AC. Once you get her out of that she runs just as smoothly Yes she did when I bought her brand new. This has gone on for so long that I know exactly when she's about to do it do it and that's only when the engine is already warm like When I park park her and go into a store For up to like 30 mins but never more Then 45 minutes. I don't think it's a fuel issue since I irregularly change the fuel filter ( Every 100 K) And about 4 years ago I had the fuel pump replaced with an OEM part. I've gotten so used to it and I know that it's not something thit's not something that's going to stop the car from running but The other day someone drove drove my car car and they noticed it.
This should work. My 280k mile Toyota sienna would crank and start and immediately die out . So I sprayed the throttle body and whipped clean and bam ! She back running good again
I did what he said....started right up...I tried to back up and stalled....now it won't even turn. :( Lights come on, battery 12.4 V....but does not even crank. What could it be???
Not sure if this is what I need to do or not. Mine is hard starting after sitting all day or all night. But once I finally get it started it runs and idles great. And if I turn it off and start it right back up, no issues. It fired right back up quickly and purrs like a kitten. It’s just that initial start. Ugh. Help!

This happens to me after I drive up a steep hill. I have a 2001 Toyota Camry le and it just happened after not having an occurrence for almost 6 months. I have taken it to mechanic and they cleaned air intake but problem still persists. Temperate gauge isn't affected and usually starts right up after I let it sit for a while. When I try to start it up before waiting it sounds like I'm grinding something as I turn the key. Have you experienced that as well?
Toni Cooper Really sorry to hear about your car. I haven't had the issue where the car does this only after climbing a hill, or the startup is making grinding noises. It sounds really interesting though, if you find a cure let me know so we can spread the good word to everybody. Good luck and keep trying!
Anyone experience exhayst smoke from the iac coolant passages leaking into the intake?... Did leak down and compression cyl test. Moisture tested my oil(clean) And my coolant is perfectly clean Last thing i coukd think of was coolant getting in direct from the intake at high rpms
Better be very careful, if you over spray you could hydrolock your engine, make sure and read the directions, id say he was very close to over spraying.
if you just removed ground cable, give it the shakes at idle also. Let motor warm up, press on brake pedal, shift into drive for 5 minutes approx., and turn engine off. Done...
Burke Batchelder I did not have to disconnect the ECU. It is possible that disconnecting the ECU may increase the effectiveness of this cleaning, but for many the car will start up properly after giving it a good cleaning.
Sebastian Balocca Sounds like you have a lot of gunk built up in your IAC Valve. This method is the simplest, yet it doesn't thoroughly clean the part. Go ahead and give it another shot, it will help loosen up the gunk. There is a more thorough way to clean the valve that is still better than spending >$500 for labor / new part. I will look into making a video soon about this method. Thanks for watching.
barely got it starting, now it tends to start right up as before. I got it starting by quickly* revving the engine (for some reason it keeps steady after doing that [sometimes]). Yah I hear you on the labor price, Pep Boys wanted 400+ labor with 300+ part... I'm thinking on maybe buying the part and replacing it myself (around 120$).... But I really want your method to work. I look forward to the video (thanks for responding)
Hi, I have a toy cam 2007, when I start the engine I have to hold it so it crank and start, but I've noticed that happens more often now, not sure if it is the started is almost gone or with a good cleaning will do. It has 180k miles. thank you
...uhmm...very good..But the most important I think you have to clean that little thing just down there...you have to take it out...and spray with that cleaner..and make sure you have to move very quickly (with your fingers),..back and forth ..for 10 or 15min.(patience),.you remove all dirt...And then ...everything is ready,..Nice and Clean../.
hey so when i start my car it shoots up to 2k on idle!! i mean its constantly at 2k when im in nuetral and when im in park...whats going on you think also sometimes when i drive it goes back forth between 1 and 2k
Chris Merino #1 Random surges could possibly be the IAC valve. There are reports online where the IAC valve gets a very heavy, caked on carbon build up, needing a deeper clean. Seafoam Deep Creep solution would be great for this. Others need to remove the IAC component and clean it with a brush and stronger cleaners. #2 Another reason for a jumpy idle is there is air leaking somewhere on your car (vacuum leak). Double check the hoses connecting to the intake manifold. Since there are a billion of these hoses, use the intake cleaner and spray near the connections, if the engine RPM surges higher that means it's getting into the system, signaling a vacuum leak.
@naomi corn Please take a look at this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8usNW4-Cuhg.html I was having that problem (in the link), the IAC fix (this current video you're watching) is what helped the car. If you are having similar problems in the link, then by all means try the IAC clean. It's much cheaper and will get you back on the road. If it doesn't work, well hey now you know it's something else! Good luck!
Please speak louder or turn up the volume on your recording. I have my volume maxed out, and I can barely hear you. What is the square object that you pointed the nozzle at? Heard NOTHING of that.
Benjamin Smith did you find out what those hoses are for? my camry only has 2 and I think they are coolant lines... im trying to find out where that little opening leads to before I spray in there. please help.
It only takes a half hour to remove the intake hose and the throttle body and IAC valve you can clean the throttle body and the idle air control valve and even the breather box where you attach the throttle body with carburetor cleaner some rags I take my sweet time because I like to clean the idle air control valve as good as possible and since I got every thing apart the throttle body and the breather box too I'm done in about an hour and a half is not so difficult this short cuts are stupid my way guarantees me peace of mind for at least 7 years or 100 thousand miles is worth it.
@ApplePie 2019 . I would if I had the time and knowledge and the proper equipment to do so. Unfortunately I don't but you do have a point and it has crossed my mind to do so . Now don't consider myself a mechanic or a very knowledgeable guy when it comes to fixing cars as a matter of fact 5 years ago all I knew how to do was change the oil and the filter of a car and that was it. But I got tired of going to the mechanic so I bought a 1995 Toyota Camry and and a 2000 Honda civic . I started watching RU-vid videos and I learned that the 3d and 4th generation Toyota Camry were excellent cars so I bought a 1998 Toyota Camry ,unfortunately I got in a car accident and the car was done so I bought me another 1998 Toyota Camry. The reason for this is that I have watched so many videos on this Toyotas that I have gotten so familiar with how to change and flush all the fluids and I performed the IAC valve cleaning on all of them including the Honda civic and I have seen how much gunk and nasty they can get the one on the 2000 Honda civic I had to soak it in purple degreaser for hours it took me at least 3 hours to clean it. I had better luck with the two 1998 Toyota Camrys but I did spend at least 20 minutes both of this Toyotas only had 110 thousand miles that's why it wasn't so difficult. My point is if you like your car and you're planning to keep it until it reaches 400 thousand miles assuming you have a 4th generation Camry that can last close to half a million miles. Remove the IAC valve every 70 thousand miles and you'll never have a problem all you have to do is remove the air intake hose and the throttle body a couple little hoses is very easy. The reason I'm kind of good in performing this jobs on this Toyotas is because I've spent a lot of time watching videos on RU-vid about this cars and this car are very easy to work on The EGR valve also requires cleaning and is very easy to get to. But you do have valid point and I'm going to start studying on how to make videos on how to do preventive maintenance on this 4th generation Toyota camrys. I have worked so much on this cars that I have actually done jobs using my own God given common sense. That I owed to others to share what I have learned. Now hopefully I can find videos on RU-vid of how to make videos lol.
No thanks, you didn't even wipe it out. And let it dry for at least 30 minutes, unless you had a air hose. But I could barely hear you anyway. Try another way, but do it right!
