Amazing, will get right on it when I have some time after X-mas, thanks for another great vid.
No problem, have fun...
Grazie per aver fatto un video così dettagliato, mi è stato di grande aiuto.
You're welcome...
Hello from Romania.
Ty for your video. These really help me. Once i open i see on the inside and outside throtle a little oil, but with a strong smel of gasoline ( e95 ). My car is ar 147, 1.6, 16v, 105hp. Anyway, the car run in almost great condition.
Inside was a little dirt, black dirt, but i clean all thing there, carefully.
In the first, car start very, very good. The running is the same, maybe a little batter on acc.
All the best,
Cheers
Thanks, you too
Brilliant Video thanks a lot i have a GT 1.8 ....nice greetings from Vienna
Thank you! 👍
Very useful guide, thanks
No problem, glad it's helpful...
Ευχαριστώ πάρα πολύ έψαχνα πολύ καιρό να βρω πώς κάνουμε reset στον

my 146 ti air control valve is broken.can i use the air control valve of a hyundai sonata as parts are difficult to get in my country
Is this good to do once every few years or only when there are problems?
Hi, is the ecu reset procedure the same for the 3.2 v6 busso?
My engine warnning light keep lights up after I change coil and spark plugs and throttle body cleaning.
Hi brother is there a used stockist or website in Italy that you can recommend me please. I’m now in Milan and need somethings for my 156 selespeed.
Thanks so much
How come the acceleration backwards from official stats
Great video, I am really scared to disconnect so much wiring on 147 as even moving the driver or passenger seat can cause airbag light to illuminate
Thanks, even if that happens you can easily erase it using diagnostics. However, if everything is ok, computer is going to register it, and it won't illuminate airbag light even if you disconnected the airbag...
I want to install a oil catch can to prevent carbon build up on my intake valves.
Can you make a video about how to install a catch can?
I'll consider it for one of the future videos...
Hi thanks for another great video. What could cause sudden high (almoust doubled) fuel consumption on Alfa 147 1.6ts?
No problem. Mass air flow sensor, and oxygen sensor. MAF sensor could be detecting air flow inaccurately, but the bigger chance is that the O2 senor doesn't measure air/fuel ration properly. Those are just two possible causes, you could also have faulty temperature sensor, etc.
@@arcgarage At least i now know where to start. Thank you very much!
Can you post a video on how to re-cover Alfa 147 cloth seats with leather seat covers from Alfa 147 please? Is it possible to do it as DIY? Keep up the great videos - good detail!
Thank you, not sure if it is possible since the profile of the seats might be different and it won't look right...
Hello thanks for the content
I have a GT 3.2 with a mysterious issue:
Only when engine cold, After starting it and idling, engine light bip for 10 seconds and disapear . Random codes: p0300 misfire on cyl 4 or misfire on 5 or misfire on 6 sometimes both ...
Any Idea or advices please ?
Thank you
It sounds like you could have an issue with coil packs...
@@arcgarage ok thanks
I have already tried New coils and spark... What about knock sensor ?

Hi. I cleaned the throttle body and the idle is really unstable since that. Does the ECU reset solve this?
It should if adjustment is the issue... If it's problem with something else, it might not...
Please tell me how can I reset learn parameters for injectors in 1.9 JTD CF4 and what about adaptations injectors then? Greetings from Poland 😁
You need a diagnostic tool for that... Greetings
I did this( also the ecu reset) the throttle body was full of dirt. But now when I stop my idle hovers at 1500-1300 for a couple of seconds and then goes to 1000 rpm. Also when switching gears rpm kinda sticks for a moment. It seems to work more normally when cold. Any ideas? I also cleande MAF.
You could have issues with throttle body...

Hello, could i spray carb cleaner without dissasembling the body entirely? would that help? My 1.8 is very jerky when I let go of the gas pedal.
You can try
I experienced that when i disconnected the abs electronic module plug. The throttle became very sensitive
the reset process would be the same if you have an scanner like alfaDiag or fiatEcuScan? I have a 159 2.2
You got the adaptation option which is used in cases like this...
@@arcgarage thank you. Tomorrow I'll check the MAF following your Maf video, my 2 issues with the 2.2jts are , a couple of seconds in accelerator lag when I floor it (specially from standing still) , and 2> allways on maximum consumption (or beyond max), it shows me 5.5km/liter or 17liters/100 km. Among those issues there is no hesitasion, no significant power loss, no erratic idle no warning dash lights, I guess a bit a clutch slippery specially after a city run. . I don't know where to beging with, so I'll start with a MAF cleanup, any ideas? good videos man, keep them coming!
Thank you so much for an amazing video. Ive check my starter ring(ITS GOOD) and ive got a brand new bosch immobilizer in but im still getting and KEY CODE ERROR. MY mechanic says i have to buy a new ECU but i havent been with him long and he hasnt always been thoroughly honest with me. could you please advise me on what i could do becasue i cant start my car with my key.
You either need to reprogram it, or buy ecu immo module and key in package
@@arcgarage do I need a new engine ecu ?
@@arcgarage I’ve bought a new immo module already (just the module no keys)
@@ricos9282 Missed the comma, you need engine ecu, immo module, and keys
@@arcgarage thank you so much my friend. can i just replace the transponder in my current key? and about the ECU do i have to find an exact serial number thats on mine ? i have found a couple on ebay for 156 2.0 selespeed that is supposed to be in working order can i just swap that in ?
Can you do video for replacing front turn signal? Mine has water inside
You can see how to remove them in this video ruclips.net/video/Xkq1eYwn_Bs/видео.html
@@arcgarage thank you
Hi can you help me ? My check engine light is on I went to check codes and it was maf sensorI but my mechanic cleaned throttle body. And it stoped showing ce light. That's confusing what throttle body has to do with maf sensor. Now it started doing it again, i rev it few times and turn on and of car and it check engine light goes away. Can it be faulty throttle body or maf sensor, also my rpms "dance" a little bit when car is not moving in neutral between 950 900. Also car runs fine no lack of power etc. Only when it happend firist time my car would turn off when coasting in neutral now it does not turn off.
You have to follow up on the parameters with diagnostic tool, but it could essentially be both, that's why follow up on the parameters is a must
Hey thanks for answering, i did diagnostic at 2 different shops, all said it was Maf sensor. I have cahange it ordered brand new maf bosch OEM sensor, and you can guess it still throws same check engine light and same code for maf sensor how ???
there is no problem to open the throttle butterfly when removed from the engine?
No problem
Really well-edited video, I have cleaned my throttle body before but might do it again after watching this video. I have an Alfa Romeo 156 2.0TS and right now I'm having issues with it, it won't rev over 4k rpm. It's not the MAF. I tried disconnecting it and it still wouldn't rev over 4k. Do you have any experience with this and if so what was the fault? I think the car has entered a so-called "limp mode", not sure though. I have a video on me revving if you want to see I could share the link.
Thanks, it is usually a symptom of the bad MAF sensor, however, it can be different issues as well like fuel pressure, poor compression, vacuum leak... I would hook it up to diagnostic tool, and bring up different parameters including MAF signal, O2 signals, injection time, etc. I can't tell you for sure, I would have to personally inspect the car...
@@arcgarage Okay i see, do you think it could have something to do with the crankshaft sensor, I've actually replaced it with an cheap 200kr about 25$/20£ sensor and in the beginning it worked fine but after maybe one month it wouldn't rev over 4k also i plugged in the car with OBD2 port to multiecuscan and I got error code P0335 RPM sensor, I tried to clear it but it just keeps on reappearing and I've also taken it out several times to clean it, it has oil on it, I'm not quite sure if it should have oil on it but I guess so since the crankshaft probably is lubricated with oil

Then it would be a good idea to start there. If it reappears constantly, it means there is an issue, either with sensor, with wiring, or with ECU(which is least probable)...
@@Meox_YT Cleaning it doesn't fix it. You'll just have to replace it. Use only BOSCH. It's not exepensive. Similar simptoms has the camshaft sensor. That one means cambelt off. And yes, should be oily because it's "reading" the teeth from the crankshaft which spins very close to the oil pan.
Was looking forward to this one thank you. Your valve was a lot cleaner than mine. Did you notice any difference after cleaning?
Also, what is the benefit of the ecu reset?
No problem. ECU reset allows it to relearn different parameters including the throttle position. It can have numerous benefits from better acceleration to smoother idle...
@@arcgarage that's very interesting. When I cold start my car the engine rpm is a bit "sticky" while the idle is higher. The rpm drops slowly I don't know why
Maybe those ecu reset can help with it. I will try it tomorrow thank you!
No problem, definitely worth a try...
@@deramon1000 bro it's totally normal. Every twin spawk does it, and not only those 😀
@@kismartin98 well before I had my 1.8 gt I had a 1.6 147 that never did it
is it similar to the Giulietta ?
Not sure...
Я перший!👍
ECU RESET works on diesel motors?
yes
How can i see if my alfa is 105 cv or 120 my friend ..do u know ??
Check the registration papers, I don't know which country you are from, you can also check the VIN number online
@@arcgarage greece my friend..
What if I clean this with wd-40?
You can, but it might accumulate dirt a bit quicker...
Wd40 годиться только в качестве смазки или для удаления ржавчины .
Тебе нужен carbon cleaner
Thought I was listening to Arnold schwartzenegger
hahaha
There's no need to do that. No effect. Pepole should take care of the 'variateur de phase' instead, because on this engine, it causes much noise and power problems when disfunctional.
