In this video you can see how to clean the throttle body, and reset ECU afterwards. The procedure goes for any Alfa with a Twin Spark engine regardless of size... It can also be used as a reference to do the same on different engines...

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.

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

@@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.

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.

@arcgarage
@arcgarage 3 жыл бұрын
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.

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.

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. .
