FINALLY, a subaru guy, a car guy that knows what he is doing, not full of BS and is not so impressed with the sound of his own voice. My hats off to you brother. Gotta love the subies!!! Got 3 of em myself. And you clearly know EXACTLY what you are doing. I wish there were more how to videos on you tube that featured the clear video, no talking material like you post here. Color me subscribed. :)
+thomas womack awesome, welcome to the channel. Glad you enjoy my videos. 👍
thomas womack heck yeah. I'm relatively new to Subaru. Love them! This guys channel has helped me so much!
has all the tools but throttlebody cleaner spray haha
I second that great video!!!!! Using the right tools and knows what he is doing.
Hey, Robert! Just a quick add to the throttle body cleaning video.
I had done the throttle body cleaning about 20k miles/a year ago per this video and all of the sudden, when my girlfriend borrowed the car (2011 Outback 2.5), it started to hesitate upon take off...but only when the AC was on. No fault codes or anything. Acted almost like torque converter slippage 😖but I had removed the valve body, replaced the solenoids and replaced ALL of the CVT fluid after having done a thorough fluid swap out (drained/filled/drained after 3k miles/filled again) prior to the Christmas lights coming on, so...🤞🤞🤞
Turned out to be a dirty MAF sensor! Cleaned it and when I inspected the throttle body, pulled the MAP sensor and cleaned that, too. Did the idle relearn procedure (thanks!) and all is good once again. I was really surprised I was getting no codes though.
Thought this may help someone.
Thank you for this information, also as you do the cleaning also always check the air filter. Mine was displaying check engine light and was still hesitating after all the cleanup until i replaced the air filter. This was after diagnosis that reported RICH AIR-FUEL mixture meaning less air much fuel. If it reports LEAN AIR-FUEL mixture, its time to check the fuel filter.
I have an 02 forester , similar symptoms but mine feel like the back diff is trying to catch up with the front diff, like my gear gets stuck on high rpm or like if it was stick and I down shifted but once I step on the gas it pulls /jumps forward.
I replaced the trans, fluids filters and still same.
But I don’t think my year has a maf sensor, I’m going to try the map /tps sensors, clean the throttle body plus add a K&N filter, read some where that helped them
Why you don't have millions of subs yet absolutely BAFFLES me
+Gavin Whiteley idk.. Haha. If that could go ahead and happen I'd be pretty dang happy though!
It'd be awesome! I've done all my own maintenance and repairs on my 2011 Impreza just from watching your videos. They're very descriptive and well recorded. I just find it odd there's not a bigger following here, seeing as you're one of, if not THE only UA-camr who goes over everything with these cars.
Glad to hear that you find my videos useful. 👍
Doesn’t seem like people work on their cars much these days.
Subaru should have a scout after you!
I just went into a Toyota training facility and there was a board filled with electrical stuff from a their car which was pretty cool to see everything working without being in a car
Fixed my stalling issue during idle relearn. Idle is much smoother now and acceleration is so buttery too. Thanks.
As a new Subaru owner who enjoys wrenching on his vehicles, I truly appreciate your videos. Super easy to follow, to the point, entertaining. thank you. My 2008 Forester and I give thanks lol
I appreciate that!

One question, Do I need to disconnect the negative pole or the entire battery before cleaning the throttle body or not?
Thank you for your precious help especially here in Italy...
Excellent video.
My favorite part- You don’t talk unnecessarily.
Worked great! I didn't think it would need it since my intake plumbing is all nice and clean on my 04 XT. I was completely wrong! Didn't need to remove throttle body, just held it open and wiped the other side.. I used crc throttle body cleaner and it shredded the gunk.
I noticed my idle was jumping +/- 200 on my XT. So i cleaned the intake and ran an idle re-learn as per your videos and it has smoothed out. Acceleration feels a little better to. Thank you so much!
absolute legend , made very in-depth and easy to understand for beginners trying to save some money
First of All, love your channel and your the only reason my wife talked me into getting her another Outback. Love/hate on this thing, my Toyota's seem to never have issues like this one(2013 Outback 3.6R). The car was surging going up hills in 5 gear with the A/C on, cleaned the throttle body(god it was bad), she says it runs like a champ now. Thanks for such an informative channel!!!

Glad to learn about the 05+ throttle bodies. I noticed my idle seemed a little off in my 07 so i got my crc ready to try this cleaning. Thanks for the clear video guide! 🍻
Surprised he didnt use any CRC cleaner on it he just wiped it
2010 Forester, 218,000 miles. Rough idle, sometimes die at a stop. This procedure gave me back a smooth idle, engine doesn't die at stops. Took maybe 30 minutes. Inside of the throttle plate looked like the bottom of a tar bucket. Probably doesn't help it uses a quart of oil every 500 miles. But it's paid for and reliable.
Thanks for this video! My 2005 Subaru Impreza was having this issue, cleaned it up and now it runs like a dream again!
Yes dude,thanks I just pulled mine out and turns out the gasket was broken,getting it fixxed now what a life saver :D
Thank you. My 2009 was bogging and stalling at stop lights. It does this every few years. The dealership always cleaned the TB but labor fees are getting out of hand so I decided to do it myself and save a bit of money and now it runs like a champ again. I didn't remove the TB fully since I don't have clamps for the cooling lines but I think I cleaned it pretty thoroughly, at least enough to get it running smoothly.
If you dont have the clamps you could fold the lines and zip tie them, if theyre old though it could crack them, as long as you make sure the coolant is topped off the little bit of air you get in the system should find its way to the overflow tank.
EDIT: actually you could find a bolt to put in the line and zip it
I always do a MAF, throttle body, and IAC clean before smog time. I also feed Simon a can of SeaFoam via the fuel system and one via the intake.
By far the best step by step videos!!
Thank you!
Thanks for the great video. No nonsense, just good info. You just earned another sub. Keep up the good work 👍👍
Very late to this party! Your video helped me take care of issue with my 2015 Forester! Only wish it was warmer outside...
Thanks for the tutorial I thought my problem was with my spark plugs and wires. So I changed them out as well as my valve cover gasket. Still have idle problem I will be trying this this weekend. Thanks.
You're welcome.
First time working on cars ever. Gonna copy what you did and full send it and hopefully my problem with erratic idle and stalling is no longer issue (Subaru Impreza 2007).
Thanks for this. New to Subaru. Was having trouble starting my 2011 Outback without giving it gas. I kept looking for IACV, but it wasn't until watching that I was able to make sense of it! Thanks!
Especially in the cold right?
I just got my hands on my first Subaru Forester Gt and your videos are helping me heaps, I owe you so I subscribed!
that digital torque wrench was super cool
Fixed a low idle problem when I turned the air con on. Thanks!
Can you elaborate on this? My idle is rough when AC is off. Turn AC on and it runs fine.
Feels like it is going to stall at stop light unless air is ON. Thanks!
@@kellyradcliff1748 that's strange.. I had the opposite. In hot weather there seemed to be a shortage of airflow through the throttle body with AC on, so cleaning it made the airflow better.
thanks very much for this video, i'd never thought that this could be so dirty or that it could cause rough idling, so got a can of squirt and cleaned mine today, wow, the filth! took me about 15 mins total, i left the 'body' in place and that includes cleaning my hands of the same filth that came out. oh, and my BL5 Legacy would like to say hi and thank you too. :D
+Phil C glad to help!
It's amazing how much Crud gets built up in there !
Nice video, now I just need the guts to do it myself! Thank you
Thank you! I'm feeling confident I can do this now.
Knew Mr. Subaru would be here for me! Just replaced my son's (horrible) 2015 Sonic with an 2006 Impreza 2.5i. In 2 weeks found parking brake doesn't work - common on an AT) power window failure (master switch) and now a P2100. I'm going to buy a new TB & gasket first...then clean it up...and replace if needed, otherwise return it. I've mainly worked on EJ turbos, so learning on this one. Thanks!
Not even sure if I need to do this to my 01 but your vids are hypnotic. We're gonna miss you when Subaru liscences you :(
+Dan D ouch. Don't put the jinx on me. Haha
Thank You. Piece o' cake. Cleaning mine on my '15 Crosstrek Limited
next week. I've used Seafood several times but I got a slightly rough idle with 109,000 on the odometer.
Thank you 🤙🏽🔥 was having rough idle/stalling and TB clean + idle relearn got me all back to normal.
How did you do the idle relearn?
I think I need to do this. My '09 Legacy started shuddering really badly at stop and idle, and acceleration feels really sluggish. And this happened when the fall weather kicked in in New England. Colder weather brings out the problems with your Subaru. Will get on top of this right away.
Thanks. I have an EJ251 in my T3 Kombi. It's just started revving high on start up. I'll do this. Thanks.
I took mine off and cleaned it with half a can of brake cleaner made it look shiny and new. the carbon on mine was so bad it was so gummed it looked like if you boiled all the water out of a bottle of pepsi
This will be next on the list! Looking forward to getting the daily running nice and smooth! :)
Aí sim, o correto pra fazer uma limpeza excelente e tirando o corpo de borboleta e aplicando a descarbonização, parabéns.

MrSubaru1387 my daughter just had our 2022 Subaru impreza service at 10,800 miles. Tech suggested throttle body cleaning. The tech uploaded pictures and to me looked like a small amount of varnish on the plate and no carbon build up around the circumference of the plate or body. Is it normal for a dealership to suggest a cleaning at 13 months old and 10,800 mile? Thanks if you respond. 4:56
Would love to see what the car sounds like before doing the repairs. Learning to do repairs on my own and those priors really help! Otherwise, love the flow of this.
So glad I found this channel. My 02 legacy wagon will be so much happier. Thanks!
Well here I am once again MrSubaru. Thank you so much for keeping my baby alive! Honestly my 01 Forester has been one of the most reliable vehicles I've owned and part of that I owe to you for helping me maintain my vehicle properly. ready for an oil change and new fuel filter too. been getting some hesitation when pushing the pedal down fast and taking off from stops so just moving through the suspects, already did spark plugs and wires and still getting it so figure its a fuel supply issue, I don't think the fuel filter has ever been replaced on this car. heck the battery I just changed was 7 years old!
great vid mate, glad you went the extra distance and removed the whole throttle body
good video. I always do a cleaning of the TB when I change the air filter, spraying and wiping. The 08 is ten years old now, this Spring I'll remove as you show. Using Mobil-1 helps keep the TB clean also I think
Saved my ass again 😂 I wish I could share what I just cleaned up. Happy Birthday btw 🎉
After normalized need any programming or no need
Thanks for your videos I have learn and save a lot of money thanks again
+Sergio De los santos you're welcome!
Well shot, and very clear. Quality job on the video!
+Cyclimbo thank you. Glad you enjoyed the video.
Clear and concise. Thank you.
I have a 2013 subaru forester and my throttle bottle was so dirty it gave my car long crank when starting. Sometimes i would crank twice. And when my car did start it sounded like it hesitated so hard to keep going. This was really random, could start jsut fine for a couple days or once a day, in the morning on my way to work or after leaving work (sitting for 10 hours). Took it to a shop and the guy right off the bat said it sounded like a throttle problem. So when they were diagnosing my vehicle it was the first thing they checked and holy hell they even sent me a picture of it. I never had starting problems since and it starts like new again.
Thank you so much for the guide! This fixed my issue :)
I will be cleaning my throttle body this weekend. Hopefully, that will get my 2012 Subaru Outback idling better. Thanks for the how-to video!
Hopefully so. 👍🏻 You're welcome.
@@MrSubaru1387 This video is what my 2012 Outback is doing... stalling when coming to a stop and the fix was replacing the torque converter. Apparently it is a known issue. ua-cam.com/video/UyzThsBh94E/v-deo.html
Great video this fixed my idle problem on my 04 Impreza, only thing is, I was trying to torque the bolts to spec and all I did was shear off one of the bolts before the wrench stopped
What kind of idle problems were you having?
@@eayala714 I would randomly idle at like 2-3k rpms almost as if the throttle cable was getting stuck just slightly
I want this guys tools. Needle nose pliers shaped to wrap around hoses the clamp iers and that snap on digital torque wrench. Gotta get me some
Mr Subaru - I'm in limp mode with a very high idle, (the idle drops a bit when I press the brake pedal), idle is normal when I disconnect the accelerator pedal. I have tried changing the pedal but getting the same result. I have also changed the throttle body. Getting codes p1560, p2109, p0607, 2138, 2135
Love the video, hate that hose clamp on the driver side. 👍🏽
Need to do this so looking on here for a vid to help. So glad you made this, very helpful indeed.
From one Scooby owner to another - thankyou and maximum respect!
Thanks for the video. My wife's 2013 Crosstrek (almost 150,000 miles) has the P0420 catalytic code, and I'm about to clean everything from the MAF sensor back, even though it starts and idles fine. I'm going to try the intake cleaner spray for intake valves (the usual direct injection issue), and see what happens. Subaru wants thousands for the cats, so I'm going to see if cleaning things might be the answer. Her mechanic said the cat job would be around four grand, and we just dropped $4800 on the standard transmission. ....oh, thanks for the torque settings.
....subscribed!!
Look at your fuel trims and see if you're running rich.
Does that little bit of black on there really make a big difference? Did you notice a difference in performance?
Amazing thank you for share your experience in fix nice and clean I love to see your videos
+raul alfredo mejia cantillo thanks. I'm glad you enjoy the videos. 👍
MrSubaru1387
When you get chance make a video of how to change Properly the sparks plugs from 2005 subaru legacy 2.5 non turbo please and I APRECCIATE your respond and like
Thank you for the video - I guess I wonder why not just spray some CarbCleaner in the intake and let the stuff drip off....am I wrong in this thinking??
I think you could also use one of those giant cotton swabs to clean it. Just spray the cleaner on the swab end and agitate.
thanks for the video from Chile! excellent step by step, I will try to clean the throttle body of my subaru impreza wagon 2003!
Great video, this worked amazing on my Legacy 2010! Quick question, if anyone is still looking at this thread, what size are the two bolts that hold on the air intake handler? They were missing on my Legacy (bought second-hand). Thank you!
hi! Thanks a lot, i have a question, it's necessary unplug the negative terminal from the battery first?
Thank you so much! You took my suggestion to do a throttle body cleaning and did it! This is my next job.
Can I use a spray degreaser for the cleaning? Great video btw going to be cleaning my legacy soon
No throttle body cleaner spray?
Excellent. I really appreciate your work. Thanks a lot.
don't want to buy any special clips to clamp off the hose lines. wonder if I can use those black binder clips (they seem strong enough). Guess I can just test one out and see if they work.
You are a legend as far as I am concerned. Superb video. BTW, I was wondering if you have this for '04 and older Subis that have the cable mechanism for cruise
Just cleaned out my throttle body on my 2009 Outback. Hopefully, it did the trick. I did notice a bit of a difference in the idle as I was sitting at the stop light.
I'm still burning a lot of gas though. It was at 16.2L/100km and I just ran it on the hwy after cleaning the TB and it's down to 15L/100km on a 20 minute drive.
Probably the fuel injectors need to be cleaned although I just had the lines blown out. Probably wasted a bunch of money doing that...
Spark plugs were changed around 170,000km and I'm at 193,000km now so I don't think that would be it.
Check your o2 sensor.
Hi Mr SubaruHello from AustraliaCan you please do a video on how to use the Upper Engine Spray Cleaner for a 2006 Subaru Liberty (Legacy) 2.5 Subaru recommend to spray it in the manifold every service, but I cant figure out how to do
Instructions are very clear on the can 👍
My 2005 Legacy is running much smoother. Thanks for the video.
You're welcome. 👍🏻
Clean the mass air flow sensor as well it will run even better
Where did you get the clamp pliers that you used on the throttle body cooling lines?
I'm surprised you didn't spray clean the electrical contacts before re-assembly
Great video as usual, about to do this on a 2010 Forester. I have an Ultrasonic cleaner, any reason I shouldn't use it for the Throttle Body? Thanks!
What's the name of the sensor or tool that warns you when you're tightening the bolt?
excellent video! Thank you!
You're welcome.
Super helpful video, just cleaned mine👍
+Maxwell McComb awesome. Glad I could help. 👍
2014 Outback 2.5 Premium owner here with a question: It has 54k trouble free miles. Dealer just did oil change and recommended throttle body cleaning at $129.95. I declined and said "next time." Is that reasonable? They tried to get me for $69.95 for cabin filter replacement which I did myself for under $20. I am more than a little suspicious.
Thank you for helping!
Good video! Thanks!
One thing I want to ask…
I’ve cleaned TB’s on other vehicles and was informed to never manually push open the flap. This triggers something and the car will need to go through a drive cycle hopefully reading right.
What I’ve done is turn the key to on, put a block on the gas pedal to open the flap, then proceed to cleaning.
My question is: is it different for Subaru?
Also…. If you take it off, why move the flap anyway?
Again, thank you very much for this video.
I’ve subscribed and plan to visit again!
Thank you.! Very helpfull.
Absolutely agreed.
Is this process similar for a 2000 subaru legacy?
Oh my god ....I so appreciate this....my 2006 Subaru Forester cross sport is having idle problems ...did an engine scan we didn't get any code or anything ....it was fine but as we removed the Maf and cleaned it ....it a little smoother but still rough ...my car has 157,900 km on it and I don't have a service history do you think this can rectify it?
+Eric Joseph possibly. Without codes or any direction to go, it couldn't hurt to try, especially if it appears to be dirty.
Ok i'll give it a try and let you know , i'll take some pictures of the throttle body when I dismount it , also do you have any videos detailing how to get to the spark plugs easily?
+Eric Joseph yes, I do, it's for a turbo, but very similar. m.ua-cam.com/video/LuB-sUi81tY/v-deo.html
MrSubaru1387 Hey I'm going to check it out tomorrow but my crosssport is the 2.0 l turbocharged ej20 is there any different procedures I'd need to note when doing this?
+Eric Joseph should be the same. Just have to remove your intercooler to get to the throttle body.
Great job. Thanks. Dealer wanted $70 plus tax. I am doing it by myself
I dont understand why you wouldnt clean the MAP sensor when you go through the trouble to remove the entire throttle body
I have a 2014 forester I had all services done but as soon as the spark plugs were changed , it started to throttle... supposedly misfire in #4 .... I wonder if it has to do with this procedure ....
thx for the nice video!
did this cleaning, as i was working on the engine some time before and saw the throttle boddy totally dirty ...
after cleaning the whole thing, i get P2101 errors while engine in running in idle. tho no problem while driving (after reset the error by computer).
Any hints on this? i can't believe the throttle body is damaged ...
Thanks for the video!
Some suggests that it is not reasonable to open the body forcedly (with finger or any other thing) as you might mess-up the factory calibration on it.
Question: Is that true?
It's not. Just don't open it past the normal range.
I have a 1998 Subaru legacy outback and I just cleaned the throttle body. What is the torque on the throttle body bolts. The video isn't for my vehicle I don't think.
How feasible is it to thoroughly clean the throttle body while it is unbolted but still connected to coolant hoses and electrical? My mechanic (another Subaru tech) says he does it regularly.
What was the beep noise when he was tightening the screw?
Thank you so much for your videos!
I'm from Argentina, I own an Impreza xv 2.0 2010 and muy check engine light, control traction and Cruise control turns on, I have already clean the PCV valve, I'm going to clean the trottel body as you explain and the maf sensor
And the question is, can I clean the map sensor too? Witch de maf sensor cleaning spray? Thanks you again!
I have a wrx sti 2015 , and it threw a p0068 throttle position correlation code , rough idle and stalls sometimes , i’m gonna give this a try hopefully it works. Also im not getting any boost any ideas ?
I've watched a few of your videos. I have a 15 forester and while driving, the car acts like it's not getting enough fuel at times and acts like it wants to stop running.
Car has 96 k miles. Just did the idle relearn, and that didn't fix it. Any suggestions? Thanks for the info
Vc so demonstrou como se limpa o TBI ou voce fez limpeza?
Por que se voce desmontou pra limpar deste jeito ai, ficou muito mau feito. Nao descarbizou nada. Agora se foi uma demonstração , blz.
Possibly dumb question. The bolt on the right side tube of the air box is missing on my 04 Impreza. That looks like it could be a vacuum tube or something under it, how important is it that the bolt is there?
