It has an ECU, it must have a MAP or a MAF, I know it has no turbo but that doesn't mean anything for the electronics.

 

No AMM/MAF or MAP but it does have an Inlet Air Temp Sender G72 and a Fuel Temperature Sensor G81 and the G81 can give incorrect readings, does the MVB value make sense?

 

both sensors have been replaced

no change

there are no errors in the ECU

can this sensor be to blame

Sensors replaced but is resistance /continuity OK. esp at coonectors?

 

can this sensor affect the engine discount

Is that under a front seat? Yellow connectors are airbag related I think  so nothing to do with engine running.

I think you're right, Pete.

there are two connectors one for the airbags and one for the side acceleration

not related, can the acceleration one cause problems

separate cables are, not connected, but in one place

The Accelerometer is only there for the side impact detection for the airbag system absolutely nothing to do with the engine 

 

when the car heats up to 90 degrees, it starts working like clockwork, why cold doesn't work well

Maybe the compression of (one or more of) the cylinders is low, so it struggles to ignite the mixture when the engine metalwork is cold?

 

 

the car starts in the cold immediately without any problems, without smoke

It was just an idea. 🙂

 

Why do you post in such a big text size?

from the computer is the size of the text, now I will correct it

I would say it looks like Google translate is being used, @Pete_Ex-Wino

да

yes

Ah, I see. 

i thought it was just me seeing massive text

 

have you checked all the vacuum and air lines for any spilts or cuts? it could be something is loose when cold and letting unmetered air into the mix but once it heats up the expansion seals the hole/gap.

only on the go at 1100-1200 rpm cold works poorly, as it heats up there is no problem. if it does not move it works well cold

all vacuum hoses are checked, the intake manifold is cleaned, when you turn off the air temperature sensor the engine starts to work well
