E46 316 ti - Misfire

[Carecaz]

Hi everyone

I'm having a misfire for months, and no one can figure it out whats the problem!
Car: BMW 316ti
Year: 2002
Motor: N40 1600cc 115HP
Symptoms:
- When I run normally, the motor runs normally, if I step hard in the accelerator pedal, the car misfire and the car dont go, the motor light blinks!
After that all comes to normal, the motor light goes off!

I changed all spark plugs, the ignition coils, fuel pump, fuel filter...

Does anyone know what can it be???

When the engine light blinks, that has to do with emissions. You will need to plug a scanner in to pull codes, for I think you have a mixture issue here, but will need the codes to ensure that you are not just throwing parts at the car.
