  • This should work on Subarus with an electronic throttle body. Please let us know how it worked for you. / mccauleysauto
    The Subaru in this video is a 2009 Subaru Forester. 1) Turn off the lights, aircon, stereo or any system in the car that draws extra current on top of the engine.
    2) Disconnect the battery for 30 mins.
    3) Reconnect the battery.
    4) Before you start the car for the first time, turn the key to the ON position but do NOT turn the engine over. Wait 10-15 seconds so the electronic throttle body or IACV has time to go to the factory programmed home position.
    5) After waiting, start the car and let it idle without any load, lights, A/C etc.
    6) Every 20 seconds or so the idle will be adjusted up and down as the ECU tries to adjust it towards a stoichiometric fuel / air mix.
    7) Leave the engine running for a full 10 mins but DO NOT TOUCH THE ACCELERATOR during this time or turn on anything that will cause extra electrical current draw.
    😎 Turn off the engine, and leave the key in the OFF position for at least 20 sec.
    9) As per step (4) turn the key back to the ON position for 10-15 sec without actually starting the engine.
    10) Start the engine and leave to idle for a further 5 minutes without touching the accelerator and without turning on other systems in the car.
    11) Turn off the engine again and wait at least 20 sec before restarting.
    12) Take the car for a test drive as the ECU should now be fully retrained.

    I was having the same issue with fluctuating and rough idle with my 2017 WRX. I'd turn on the AC or rear defrost and the car would start shaking and the RPMs would dive. The engine was also making a whining\ticking like noise for the first 10 minutes. Did a drive with a technician from Downtown Subaru in Toronto and was told it was normal because of the type of engine it is. Glad I came across this fix cause it absolutely works and fixed my issues. Maybe Downtown Subaru should start watching CZcams videos!

      Not normal, i have a 2018 forester, with 20k miles, tec at subaru said it was a dirty throttle body.. i was like dirty with 20000 miles. Did research and found out it was obviously something electronic, was suggesting to change to a high power battery, not the cheep subaru one tho

      @@teebzr5975it can absolutely be just in this computer parameter issue. The computer learns as it goes and if it gets outside parameters that allow for weather, elevation, humidity, battery life and many other factors, those parameters have to be reset. You could make someone believe they have an expensive issue when they do not. The only reason I am back here is a refresh on the steps, as I know it works. It’s the actions needed if you do replace any sensors or your battery goes bad also. New sensor or a new battery, any time the battery is disconnected, these steps need taken. A wonky idle from these cars may not be ‘normal’ but given what I know, after owning one for almost 10 years, it’s not abnormal either.

      My 2015 will drop in rpm once every few minutes for like a couple seconds after idling for 10-15 minutes and if the AC is on even just a little bit then it hesitates when shifting but I heard that’s kinda normal cause the engine is working hard to run and have the ac going at the same time.. I swapped the battery out cause the old one was going out. But doing these steps actually worked for yours? Cause we have the same FA motor

    Yeah, this hack works! My 2015 Forester 2.3 Premium 6MT (66K miles) was having a somewhat rough idle for about a year, down at about 600-700rpm when sitting at a stoplight or in stop-and-go traffic. I followed the procedure in the video, and to my surprise...it worked! It now has a smooth idle at about 850-900rpm, just like it did when I bought it new.
    I replaced the battery about two months ago so it was without power for a day, but after installing the battery I did not let it idle for 10 minutes, nor did I wait 20 seconds on off ignition and then restart and let it idle for another 5 minutes, as advised in this excellent video!
    Thank you, Subaru support, for never advising owners that when the engine management computer loses power that there is a friggin' reset procedure for the engine idle that has to be followed, like there is for the front driver's auto power window. Tossers...

    2008 wrx, built and pro tuned here:
    had the same issue, downshifting and coming to a stop my car would just barely not stall out every single time.
    It's been really making the car feel like shit and I was tempted to sell it because I checked the maf, boost leaks, Vaccum leaks etc and nothing, I thought even maybe the tune was done incorrectly.
    I followed the instructions and holy cow I'm literally in shock that it actually worked, I've never been so relieved in my life, well maybe that's an exagération but you guys get it.

    It worked on my 2012 Subaru Outback 2.5i with 88,000 miles. It recently had a new battery installed, then started idling erratically at stop signs and stop lights. It even stalled a couple of times at stop signs. I was told it was likely a dirty throttle box. So I cleaned the throttle even though it looked shiny clean to me. However it was still idling poorly afterward, so I did this idle reset. Now it purrs at stop signs. It likely saved me hundreds at the dealership! Thanks for posting!

    Incredible! I was hesitant when I came across this video but it worked like a charm on my 2014 Subaru XV.
    I had removed the battery for a short period of time and after re-installing my idle was very rough and would stall out when I began to break and come to a stop.
    All my dash warning lights would light up and freak me out thinking I’d be in for an expensive trip to the mechanic.
    Fortunately, after following the steps in this video, the idle returned to normal and is driving brilliantly!
    Thank you!

    Thanks so much! My 2016 Forester was disconnected from the battery for a few hours during an update of the Starlink system at the dealership. After I returned home, the Forester began to idle very low (~500 rpm), and stalled 3x. Your tip to reset the Idle Speed setting and get the car to ‘relearn’ the idle speed was awesome. Everything’s back to normal (or even better than normal)!

      I just changed the battery on my 2017 forester, I notice it idles kind of low when the AC is off, but it seems okay when the AC is on...
      Also, my driver windows buttons for driver and passenger were acting up, the driver's side was not going down all the way without holding it down, and the driver's passenger windows button was not working....
      other temporal issue was setting back the date, it was only allowing me to set the hour and it didn't allow me to change the minutes, date, etc. but it worked out later after turning off and on the car couple of times.
      seems an array of issues comes up after disconnecting the battery.

    Thnx for the video. Here's my story. I have Subaru Outback 2,5 165hp. The rpm dropped very low when coming to a stop. Sometimes so low that the engine stopped. I did a reset. And the car is working fine after two days of intense testing. Because I'm a bit lazy I did my reset without unplugging the battery. I turned off all the electrical systems. Turn the key into the contact position. Leave it like that for 10 seconds. After that I started the engine and left it running for 5 minutes. Repeated the process twice. Ta-da my car runs like new.

    Have an 09 Forester 2.5 NA as well. Car was parked for 6 weeks while I recovered from a surgery. When I charged the battery and started it up it ran like garbage. Idle had a mind of its own. Bogging right down at red lights or in reverse. Climbing like crazy when the AC compressor cut in causing it to speed up and slow down with the same throttle depression. It was very annoying. Thought I had bad gas so I got it down to half tank and filled with premium and dumped a bottle of injector cleaner in it. Still no luck. So I pulled everything thing off and cleaned the maf, changed the air filter and cleaned the throttle body as well. Still no luck. Decided to call it quits and take it to a mechanic to try and diagnose it correctly. One day before my appointment I stumbled across this video. Followed the steps exactly and it fixed the issue immediately! I didn't know there was a specific procedure for the relearn the first time so I just hopped in and went! I'm so glad I found this video. It likely saved me hundreds of dollars, and with all the extra stuff I did to try and fix it, the car is running better than it ever has! Thank you times a million for posting this. It helped me, and what seems to be many others as well! Cheers!

    First off, thank you for the video. Out of the blue, my mom's 2015 Subaru Outback's engine started idling rough and she put it int Drive. I checked to see if there were any loose wires/rodent chewed wires/intake duct restrictions but couldn't find anything. The car has always been serviced at the Subaru dealership but even then, I found that both battery terminals were loose even though they were over tightened. On top of that, a "technician" apparently painted the terminals and clamps with some black paint and there was very little metal to metal connection. So I cleaned the terminals, bent the clamps so they wouldn't rotate when tightened and followed all the steps in the video. Worked like a charm.

    The steps shown here work for performing the idle relearn procedure on certain Subarus, but I would suggest making one important correction to Step 2. Disconnect the NEGATIVE battery terminal! you should never try to disconnect the positive terminal first as was demonstrated in the video. Always disconnect the battery starting with the negative terminal. Conversely any time you reconnect a battery the negative terminal should be the last terminal attached. Vehicle damage, property damage, and/or bodily injury may result if you inadvertently create a path for electricity to flow between the positive terminal and a chassis ground.

    Came for this fix and it worked. '10 Forester 2.5l 4spd auto w/101K mi, spark plugs and wires changed but had a low/rough idle near stalling, but fine at speed. Fair independent Mechanic didn't notice or know to reset idle. Subie forum described fix, video showed steps, and I just confirmed. Shortcut was I only disconnected battery for 25min. Followed rest of the steps. All good. 👍

    Radio and climate control are automatically off when you reconnect the battery regardless if you turned them off beforehand.
    This worked for me, even though a lot of people seem to be skeptics of this process.

    I own a 2003 Forester with a 2.5L NA engine with this problem. I compared pics of a Subie electronic throttle body with mine, and they look pretty different - mine might not be even "electronic." Still, I followed the procedure and surprisingly it delivered on idle smoothness. But during the '10 minutes test drive' step I noticed an issue: when I floored it, there was some misfiring and poor acceleration compared to before. So I turned the 10 min test drive into a 1 hour drive where I mixed normal driving with flooring it (either taking off from lights or entering a freeway). The acceleration characteristics got better and better over the course of the hour. By the end of the hour acceleration smoothness and power were excellent. I should add that with a mighty 110 kW "flooring it" will not exactly smoke up your tyres lol. I also noticed that engine start up and shutdown was very crisp when turning the key compared to before. Final test: I filled her up on regular 91 for a mileage test and it equaled the best efficiency I'd ever gotten out of the motor (9L/100 kM). I'm not a mechanic, I can only guess that the early gen computers were slower learners than more modern ones - if I change fuel octane I often get similar complaints from the motor until it gets used to it. Still, the "tweaked" version of the instructions in this vid worked very well for this YT random.

    I was experiencing a rough idle when I would come to a stop or if I was in park and turned my air conditioning off, yes that's right, off.. my oil temp light, AWD, and sport mode light would flicker while it happened. I was getting pretty worried, it's an 08 Impreza 2.5i automatic. I cleaned my throttle body, and then tried this and it's back to normal. Thank you so much for this video McCauley'S auto!

    I am crazy grateful for this suggestion. I've had my car serviced multiple times and they've never been able to solve this, usually just saying "that's how these older cars run". But I often found a loss of power when accelerating from a stop and a rough idle that would drop rpm to stalling. I followed these instructions exactly and it now runs absolutely perfectly.

    I have had no major issue with my 2009 Legacy 2.5i limited. (knock on wood). I just hit 108k miles so I decided to have some work done. I had the exhaust replaced and recently the catalytic converter. After the cat converter was replaced the car wouldn't run right. I had the check engine light, traction control and cruise control flashed with no use of cruise. The car would shake bad under 5mph. I watched this video, performed the steps and the car idles and runs like new again. I'm still surprised but wanted to share my results. 200K here I come.

    This worked for me only after I cleaned the throttle body. 08 Legacy kept wanting to die at every stop. Changed the coil plugs and wires only to have it run worse. Cleaned the throttle body with new gasket and did this procedure. Now it runs remarkably great. If you try this and it doesn’t work clean your TB and repeat. Omg it actually worked

    Thanks for the video. Worked on a 2003 Subaru G3X justy. After changing the battery the idle was unstable, and it would stall if you went off the accelerator to quickly. Trying to hold the idle with the accelerator resulted in the check engine light to turn on. Now the car is back to normal and the owner is happy. Wonder how many Subaru/Suzuki mechanics has been sitting in these cars drinking coffee and looking at their clock while charging customer's for ecu idle re-calibration😂

    I rarely comment but I HAVE to say this actually worked for me.
    I have a 2010 Forester and after having the airbags replaced I noticed it was being a bit funny when slowing down to a stop.
    I rang the service department at Subaru who said it shouldn't be an engine issue as the guy only disconnected the battery when replacing the airbag but to bring it in for them to take a look at it.
    Fearing they would charge me an arm and a leg to do so, I thought I'd try the internet first and found this video.
    I did the above procedure not having ANY expectations it would work but to my utter amazement ..it did! So thank you so much guys for sharing this info!!! I can sleep easy tonight.

    I never believed this "remove battery" stuff. I had idle problem since I bought my Legacy Outback 1999 2,5 petrol/gas. I own it for 1 week now. When I was stopping, my engine revved up from 2000 to 3000 rpm. It was annoying. When rpms dropped, it dropped not to 600-700 but 1200-1300. Check engine was coming up frequently. I checked vacuum hoses, connectors. There wasnt a difference. I did what this tutorial showed. I drove 25km outside city, about 10km in city and for now I wasnt noticing anything strange or mistical revving. Hope it stays like that.

    2014 Subaru Forester - went through the process and it worked. I'm grateful to have the racing at start-up finally resolved. Overall that car has been a major disappointment with having Subaru replace the engine due to the oil leak lawsuit, the transmission value failure, recall and replacements of the rear spring, and replacing all the wheel bearings. I swear they used to say Subaru were reliable and I fell for it. Would never buy another one or recommend it to anyone.

  • @allsortsofrubbish
    @allsortsofrubbish Před 8 měsíci

    Subaru has throttle position adaptations values that are stored in ECU memory. If you disconnect or remove battery or even clear errors, ECU will reset and will lost all adaptations. And if throttle body is dirty, you'll get rough idle or even engine stall.
    So, after ECU reset you should:
    1. Clear throttle body
    2. Turn on ignition, but do not start the car.
    3. Wait until ECU completely boots. Usually it takes about 5 seconds. Just wait util speedometer needle comes back.
    4. If you have EJ engine, you should learn throttle plate position. Press accelerator pedal 3-4 times. You could hear throttle is moving. If you have FA/FB engine, you don't need to do throttle position learning procedure, but of you do, nothing bad will happen. But you won't hear the throttle moving because it does not move on later ECUs.
    5. Start your engine.
    That's all folks!
