You're also getting knock retard when you blip the throttle.

Did these issues begin suddenly?

Is your car stock or modified?

Are there any check engine lights?

[vanaxxx29]

I didn't notice the problem before. the injectors have failed.


What was accomplished.

Replacing injectors.

Replacing oxygen sensor 1 bank2

Cleaning the throttle valve

MAF cleaning

I removed the second oxygen sensors

Replacing spark plugs

Replacing coils

Compression measurement in cylinders is normal (12) slight difference +-0.3

There is traction in the engine, the gas pedal reacts quickly, there are no errors from oil change to change.

YES STOCK

no engine errors

Yesterday I increased the parameter in the Engin-fuel firmware - flow rate - injector const by 15% and set the value = 0.04402.
and wrote a new log
