Hi mates!!

Could someone make a dump with both catalytic converters (are two) and both lambda probes (are 4) off? The ECU is Bosch ME7.1.1.

I have some problems with this car. When the car is warm it starts to fail, the failure are missfires. Missfires become at any cylinder random.
The car has new sparks, tested the inyectors and coils, and swap the engine ECU, but the problem still.

I attached the ori dump.

Thanks in advance.
