Just cleaned my 99 Corolla with 260k miles on, it was running poorly, but now it runs a lot better. When I opened it, was COMPLETELY black inside, it ruined the whole cloth. Thank you very much for the video.
Shay,they would take it off completely but do what is done in this video and long fingers really help plus leave it to air dry for 15 mins before refitting the hose back.It's an easy job you'll save lots of money on youtube looking after you car with videos like these just spend a little money on a socket and spanner set it'll pay for itself in one job at the garage.I do ll these on my car and i'm not a mechanic not mechanically minded.
My 2000 Corolla (which doesn't use a drop of oil) has a 1zz-fe with 2 dead oxygen sensors, an exhaust leak and almost 280000 miles and I doubt the throttle body has ever been cleaned. I've had it almost 2 years now and the thing has never failed to start even with temperatures down to -20 Fahrenheit, and other than the exhaust literally falling off and a brake line popping (luckily in my driveway) the damn thing has never broken down or disappointed me. Best 400 bucks I've ever spent!
Man you just saved my life !I just finished cleaning my 01 Corolla´s throttle body, and all the sudden white smoke all over the place. Jajaja I almoust went crazy. Thank you soo much for that clarification, you rock !
Great content sir.👍🏼 However, the throttle body has its own specific cleaner, and not brake cleaner. I heard using brake cleaner could do more harm than good; I might be wrong, please clarify me sir.
If you keep it off of the rubber parts or don't let it sit for long it should be right, but carby cleaner itself can be bitey too, same deal. Successfully cleaned out my throttle and iacv and now car is running better.
I'm glad you used a standard Non-Chlorinated Brake Cleaner. MAFS and Throttle Body Cleaners are expensive marketing gimmickry and are essentially the same product, and most of the Toyota Dealerships Mechanic's just use Brake Cleaner! General Rule Of Thumb here...must evaporate reasonably fast and leave no residues!
You can open the butterflies on a fly by wire throttle body, Just move the butterfly slowly and you will be fine. You shouldn't use brake cleaner as it leaves a residue. Use a throttle body cleaner. It doesn't leave any residue.
@@bundysgarage Some brake cleaners do leave a residue. I was told this by a Toyota master technician. Use brake cleaner on brakes and throttle body cleaner on throttle bodies
Not exactly the same thing but very similar. I use brake cleaner to clean throttle bodies, valve cover gaskets, transmission solenoids, brush my teeth with it and use it on rashes. 😜
Hello, I did a test, I removed the rubber from the air filter, so I had access to the throttle body, I started up and gradually covered the air intake that enters the IAC valve, as the covers stretch to stop until when completely covered, the engine stops. But I can't find the fault, which is that it starts and as it warms up the rpm goes up to almost 2000 rpm. Then when driving on the street or highway, if you leave it in neutral, the rpm goes up to 2000 and goes down to 1000 until in a moment if I stop the car they go to 2000. A query, I made contact, I measured the female card of the IAC with tester and 12 volts to the positive (black cable) arrive at the connector, nothing to the ground cable and the other signal 0.14 volts and the signal 0.14 volts..., I also tell you that if I disconnect the connector from the IAC, the car runs and does the same problem. I am very concerned that it may be the ECU that may be sending an inappropriate voltage. thanks for your help
probably fucked with your limiter screw on the throttle body, at 3:26 you can clearly see it limiting the throttle assembly when he is just playing with it. (right angle metal off the side and the screw is above that, 10mm socket and i think 3mm alan key adjust it till your warm idle is about 700 rpm and cold idle is 1500) EDIT: i assume that the iacv will get no voltage due to MAF sensor seeing above idle airflow and retiring the iacv as it is revving or so it thinks.
Hey I have an 03 toyota matrix xrs. I cleaned the throttle body and afterwards it revs super high. After leaving the car on for a bit it seems to adjusted the idle by itself but whenever I step on gas while in gear or in neutral, it revs up high but stays revving high and dont go down. What do I do?
I think the whole thing is a scam! My dealership offered this to me for $282. And I don't see any throttle cable in my corolla 15 like my older cars used to have so I'm sensing it's a flyby throttle! Thanks for the info! My car has started to hiccup a bit at low speed like starting from signal to move, do you think it's due to the throttle body? 65k miles, fresh plugs and ignition coil.
Sorry but you never want to spray brake cleaner were it may lead to plastic or rubber parts, it breaks down the plastic rubber molecules and breakdown. Theres o rings on the throttle body on the rod that spins the butterfly plate, rubber gasket between throttle body and intake manifold and intake manifold itself is plastic, use throytle body cleaner and on a towel and use goggles and gloves as all this stuff is bad for you. On some older 1zz-fe the intake manifold are metal. Sometimes so "precentative maintenance" can lead to worst if not done correctly, if it aint acting up leave it alone.
open the throttle so you can see straight through, and spray carby cleaner into both IACV ports and let sit, then run, will turn the buildup into smog and a clean iacv, just did this today.
@@stevejette2329 certainly is, running better now, had to adjust the throttle stopper screw cause it was set a bit wrong. Might in future port the iacv so it is a less sudden turn for the air, might idle nicelier, but otherwise this 20 yr old rolla is purring fine.
@@stevejette2329 certainly, if you want i posted a couple vids on my account after i changed the intake on my rolla, you can apprec the old girl if you wanna look anyway, sounds awesome
I have a 2006 toy corolla mine is electric no wire. Where is the idle air control valve located? Can you nake a video on the same make model yr locating the iacv?
Would WD40 do any harm on the throttle plate edges and circumference of throttle body to ease sticking? Also you should do a vid on how to bleed the coolant as that's what scares me about taking the throttle body off...
onced cleaned is the butterfly flap supposed to create a good seal when closed? I did a smoke test and i noticed smoked leaking through this butterfly flap. is that normal?
LOL Haynes Manual for Toyota Corolla July 1997 to Feb 2002 : Fuel and exhaust systems 4A*7, you can read : 11 Fuel Injection system - testing and adjustment : 6 Remove the air intake duct from the throttle body and check for carbon and residue buildup. If it's dirty, clean it with aerosol carburettor cleaner (make sure the can says it's safe for use with oxygen sensors and catalytic converters) and a toothbrush (see illustration).
I have an 01 Corolla and want to clean the throttle body, do I really need to unplug it and take the piece off or can I disconnect the battery and clean it. I've seen other vids and they say to disconnect and remove the piece.

Bro good video, but take that metal watch off when you work. If you touch the battery posts and accidentally make a circuit youll be in a world of hurt, or worse.

This is kinda true but the throttle body cleaner has a bit of lubricant which helps parts move a little bit easier.

So what is that electrical part on the side of the throttle body? And shouldn't you be using carburetor cleaner?
So is brake cleaner and throttle body cleaner the same thing?

You didn't mention shooting some into the idle air control circuit, the little square hole inside the throttle body.
