i have a 2003 rx300 approximately 165k i bought from the original owner i’ve noticed just over the past few weeks that my cars idle has been sporadic. the other day at cold start say 30 degrees it would start but wouldn’t stay idling unless i sat with foot on pedal and as soon as i let off it died out. sometimes it will idle high then come down quite a bit as well. Does this sound like it could be the same type of issue? You said you used Brake Cleaner to resolve? Thanks!!

[@lmbarne]

Thank you!! Our 2003 RX300 started, but wouldn't idle, exactly as you described. But, by following your instructions, my husband was able to fix the problem. He needed a little WD-40 to loosen the twin hoses after removing their 10mm clamps plus a little more and a couple of taps on the air control valve's screws to get them turning. But, after completing the job in less than an hour, the car runs better than before and you saved us a tow and a trip to a mechanic! Excellent how-to video! Thanks again!

@lmbarne read your comment and was curious if doing this helped your Rx300 substantially? our 2003 rx300 just started having this issue as well and i was actually thinking about taking it in but stumbled on this video. did it take your husband a long time to do ? i was able to change my starter on this vehicle myself with help from YT i think i can do this too Thanks!!

[@frederickdavid7644]

Hey Revit Auto, thanks a bunch for the video and how to fix the IAC. My family and I depend on our Lexus and money has been tight lately. This fix worked on our 1999 Lexus RX300 exactly as you have shown in your video! 😊 Lastly, it means a lot to my wife that I got our car up & running. It has a great deal of sentimental value since the original owner was my father-in-law who passed away back in January 2021. My wife took it pretty hard when her dad passed and our Lexus means the world to her since that is all she has left of him. That's how much of an impact your video had on my family's life. Thanks again and take care.

[@Revitauto]

So glad we could help.

[@YamiRich]

I just did exactly what you did in this video and now the Lexus RX300 starts right up and has an idle. No more car stalling. Thank you very much sir!!

[@calvinsmith4310]

4:44. At that point, I take the hose off and block off the exit pipe that's attached to the idle control valve. I then fill up the breather hole with throttle body cleaner until it over flows. I then move the wheel back and forth. I then fill it again as some drains out and repeat. I then leave it for a few minutes, then I unplug the pipe. Doing this fills the chamber and cleans the underside of the value which is what actually gets clogged up preventing it from moving freely. I also take the opportunity to clean the throttle bodies and butterfly valves. You can see the dark edges around the butterfly valves which just need a few squirts of the cleaner then a soft tooth brush and a clean lint free polish cloth to wipe down. On this vehicle, they're operated by the throttle cable. You can engage the throttle cable to open the valves which means it's not drive by wire and no problem with touching the actual butterfly valves, very carefully and gently still.

[@redtabby5847]

Thank you very much for your video. I own a 2000 Toyota Windom 3.0G in Japan, which is the same model as the ES300 in America. In my case, the idle speed would not drop below around 1200, so I tried the same method and the idle became low and stable. If anyone is considering replacing the IAC valve, I think they should do this first.

Truly great video. Thank you. I bought my 2002 new with 4 miles on it in Nov 2002. Now with 168,250 it has been a blessing of incalculable value. Mine runs really well. I just replaced the pcv valve which I strongly recommend every do every 30k miles. A $10 part and a 10 minute fix does wonders. I also run a can of BG 44k in tank (pour in before filling with gas) every 10k miles. This keeps the throttle body and lots of other parts squeaky clean.

Thank you for the video, great information on how to repair. The screws can be issue. Had to remove the air box to make room for hand impact tool, even that didn't seem to budge (housing not that sturdy didn't hit to hard). Soaked with pb blaster and grabbed with small vise grips. Was able to finally rock and remove the screws. They seem to freeze in the housing not the threads.

Hey same here. If I were you, I would tap the screws or the surrounding solid metal body of the IAC to the loosen those screws prior for better removal. Today I did it, and tapping it with a hammer helped a lot! If it weren't for that, for sure I would've stripped them.

I've had to do this job twice on my ES300. I've found it easier to just remove the whole throttle body assembly and take it apart on a table or bench. I did it once to clean it and another to replace the Felpro gaskets I put on with toyota gaskets because the felpro gaskets were too think and caused it to seep coolant.

Thank you so much. How did that fix go?

[@jimmydrakopoulos2140]

Thank you for your response. I removed everything as in video. Pretty simple. I cleaned everything and used q-tips until I was satisfied it was clean. Intake was cleaned throughly. All hoses placed back. I replaced Philip screws with new stainless steel screws. Start up was not normal because of excess carb cleaner but then idle remained at 2000 and climb to 3000. Depressing the accelerator did not help.

[@Revitauto]

Jimmy, be sure to comment on the same comment thread. It makes it easier for other people with similar problems to follow the diagnostic. Thank you for the more in-depth look at what was going on. I would go ahead and take everything apart, make sure that the idle air control valve is moving freely and not just stuck in the open position. Upon reinstallation double check every single hose connection and verify that they are all tight with no leaks. If you accidentally leave a hose on, you will have the condition that you describe. They call it a vacuum leak. If you recheck everything and there is nothing wrong upon visual inspection your idle air control valve may need to be replaced as it could be in the stuck open position. Be sure to take it apart and assemble again! Let me know what you find! -Blair

You made it look do able,I think I’ll try it, MUCH MAHALO’S from Hawaii

[@Revitauto]

Howzit brotha! Learned that from my buddy Colin Jevens!

[@Hizenbird]

The reason so many are stripping that screw is because it is NOT a Phillips head screw driver. When the dot is on the screw head that means it’s a Japanese type of screw similar to the Philips head screw but has a slightly different head profile than our American Phillips heads They are Japanese Industrial Standard screw heads. The screwdrivers can be found online. Better to order before you need than.

[@Revitauto]

That is so cool! Thank you for sharing, could you please post a link to those?!

[@larrybird8293]

Thanks for the GREAT DETAILED video; the engine in my 2001 Toyota Sienna is identical to the one in your video! Was unable to remove the IAC from the engine to clean it in the same way you did; the screws would not budge. However, I removed the tube from below the IAC, plugged it and then sprayed cleaner into the hole in front of the butterfly valve until it was full, let it sit for about 30 seconds, removed the plug and let the cleaner drain, waited a while to dry before reassembling everything. This appeared to fix the start/idle problem so far. I think one of the screws on my IAC is stripped. In video you said one of the screws on your IAC was also stripped; how did you remove it? And how did you loosen the other screw?

Can this be done without removing the plastic motor housing? By spraying the cleaner in the port and flushing it out through the lower tube?

[@drewfogg7607]

Great video I did everything the exact same way came out great

[@kenpodad7316]

Why not using carburetor parts cleaner? Since many others use that instead of brake cleaner

[@Revitauto]

You could use either! If I had carb cleaner at the time I may have used it. But I also like that brake parts cleaner does not leave an oily lubricated surface.

[@dongnippano156]

Four things. I have an 02 RX 300. Never use brake cleaner on this. You’ll blow out your cats or O2 sensors. Use throttle body cleaner or mass airflow sensor cleaner. Buy a JIS screwdriver for those two soft brass screws. Phillips will not work. Next, wipe around the throttle plates themselves. They have to open and close flush with the sides of the body. Push them open SLOWLY or you will damage the motor that activates these. And lastly, put a rag under the hose when you drain it out. Otherwise it will cause a mess. Or you could deteriorate your rubber hoses.

Would appreciated any thoughts.

[@carospereman3537]

Go for a long drive going about 80 miles an hour. That will clean out any carbons

[@petersmith5219]

IT IS NOT A PHILLIPS HEAD - the small dot indicates it is a JIS screw and you will strip JIS every time you work on a late model japanese car. If it had "stars" between the flutes it would be a Posidrive. There is a massive performance difference between each type.

Hey I have a very important question I did exactly what was in the video to the exact same car and when I took out the two Phillips screws from the sensor mine did not turn freely and was stuck completely I cleaned mine just like you showed me and then it was so smooth afterwards it turned really freely so I put it all back together exactly in the way that you showed and exactly the way I took it apart, now the car starts right up better and different in a good way then before but my RX300 is now idleing high at 3000 RPM’s or a little higher and I did not do that before ….. is there some kinda way to have the car relearn the sensor or something ??? Please help because I can’t drive the car at all now because it’s ideling way to high to put into gear ?? Please please help me thank you and your videos are the best

[@Revitauto]

Thank you so much for the detail!! I think what you are fighting is a vacuum leak and not a sensor relearn issue. Check all of the connection in the car for air that would enter the engine in a location it is not supposed to. Check for loose hoses and intake boots that aren’t put on all the way. You will likely find it to be a quick and simple hose unplugged ! I will check here again to see how your progresses

My cat 2000 RX 300. Did this same thing without me having done any changes. Kind of scary when you are expecting your car to cruise to a stop and instead it speeds up. In my case the cable or something got stuck occasionally. I cleaned it up with WD-40 I think and have never had the problem since.

@@Revitauto I'm not sure what happened but the history was that I had filled the tank with 93 octane fuel in prep for selling the es300.

My 02 RX300,kicks into gear very hard,when accelerate,do you think the trans shift solenoid causes this symptom or it’s just a dirty clogged filter and old fluid or something else ? Thanks

[@Revitauto]

I see you made another comment about a high idle. I would address the engine idle concern first and then check what is going on with the transmission after.

What rpm was it ideling at Before & AFTER?

Brake cleaner instead of throttle body cleaner?

Hello Revit Auto, my 2000 Lexus ES 300 starts out with very slow pick up - it sounds and preforms like a 4 cylinder.. Once I get up to about 40mph, the acceleration returns to normal. Could this likely be a Throttle Body position sensor problem? Thanks!

Any suggestions for my 1999 lexus es300? Low idle. Slow stuttering take offs. Wont shift into 4th gear. Please help

Carb cleaner works just as good right?

[@Revitauto]

That would work very well! Even better !

[@juanerivas]

Which cleaner did you use?

[@my_name_is_chef4856]

Don’t forget to test before you pick up tools. Because if you don’t Murphy will make sure you have to get them all back out

[@Revitauto]

HAHA! This is a fact! Happy Motoring- Blair

Would this work on a '02 es300? Idk if the engine is the same and stuff but I'm having the same problem.

[@BookedDolphin80]

Cleaning it did work but on the es300 it is a little different. Following The Car Care Nut's tutorial was more accurate for the es300 model. Thanks!

What is the liquid that you used named ?

[@evelynnveleni]

Can I use carb cleaner as well?
