engine running on all cylinders at cold start

[method]

Giulietta 1.4 170km, mileage 41 thousand

for some time I have like this: in the morning when I get the car garage in the underground garage (temperature about 15 degrees) engine works absolutely fine after his departure, after some 200 meters starts to run on 3 cylinders (most likely) when accelerating to feel the vibrations and a significant drop in capacity after about 1.5 - 2 minutes, everything is back to normal, never zapalila I no light is

if the car is parked on the street at a temperature below 10 C. after firing the engine runs very nierowno - as if on 2 cylinders, revs jump, the exhaust emits a very strange sound, it seems that now, zgasnie, when I warms up a bit everything comes back to normal, again no indicator or message, if you leave too early, symptoms will be as in paragraph 1

the car after the factory warranty, przedluzonej year. I was with this ASOthe car after a night at 0 st gave the same symptoms as in the above, body computer zanotowal only "rough work the engine" wyjete were candles, the one with cylinder # 1 was wet (flooded with fuel). Due to the fact that 30 thousand candles had been replaced by ASO again to me yesterday wymienilo under warranty parts (NGK plugs). This morning the symptom is the same after 200 working on 3 cylinders, the return to normal after approximately 1.5 min.

someone had similar problems? are there any suggestions on what to do next?
the problem is that BC does not mark the specific error, but this engine roughness

what BK to the ECU engineand take, the program alfaOBD and pour all modules..... what are your ECU, make, model.
I don't know what ECU, but in these the enginech after replacement oil makes probably fit and recommended below
NOTE: It is recommended to execute the 'UniAir actuator dispersion correction' procedure after this procedure.


so it just was not the pump from valve timingat

[method]

not to sit in this and don't know yet, so I'm probably the ECU

podlaczali on the website for your computera diagnostic and nothing pokazalo you think thanks alfaobd learn something more? I have a device for wpiecia not to split the obd still flew for fun with the app torque on android

honestly, meant, that, well, something is defective/replacement under warranty przedluzonej so I did, and as it is not known that it can only be me

- comrade above is well advised.
- no errors this does not mean that there are no problems.
- for example, błędnę sensor external temperature.
The ECU delivers a mixture of at least complemented by some kind of candle does not burn in the cylinder.
- how engine a little heat is the pump, otherwise it will set the valves and the cylinder starts to smoke.
- Yes, diagnosis of these new engines is not easy.
- read and see that there are no errors, that's not all, it's only 10 % of the work.

If I'm not working one or more candles is the lack of firings is normal engine gasoline, as, for example, tear or puncture on the wires, it will not give sparks. Problems arise from a lack of electrical contact

[Wieri]

I have started working on 3 cylinders when it was the Multiair module.

@ Belly-156
don't think I have before that is a minor issue with no electrical contact, the plug on one of the cylinders it was not docisnieta after replacement, for example, and once kontaktowala, not once, but then, in August, check engine, not to enable the dynamic mode, etc. the problem here doesn't seem to have any other gasket.

Maybe this weekend I will try to connect with the program alfaobd and I'll try something wypatrzyc and if not, then I will meczyl ASO further testing.. fortunately, the problem is only seen on the cold moments engineso that does not prevent, yet so very casual use, but nevertheless meant that all played as it should from start to finish..

@Wieri
I hope it's not, although if I had confirmation that the specific faulty module/podzespol that I can demand a replacement under warranty

[lechtak]

I put on the ignition coil, but why the ECU sees loss of spark?

[argo]

I have identical symptoms, and the diagnosis of the service - changing the activator

[bubu321]

@argo
- and you can write what oil sat how often is it changed, as now you have mileage.
or after the change oil was performed a process of adaptation "oil".

ps
- I'm afraid I'll be waiting to read the mileage colleagues above.
