2018, Toyota Camry SE 2.5 l.

It has brand new spark plugs. It has brand new fuel injectors. I changed the coils and the same codes pop up. I checked the spark for the coil on the spark plug and it is good. The compression is good. I cleaned the mass airflow sensor I cleaned the throttle position sensor.
Brand new fuel pump and fuel filter.
I cleaned the 02 Sensor.
I am not sure what else it could be.
When the car.
Is first turned on. It only has a little bit of a misfire. When I disconnect cylinder two, it will miss fire more. When I go to drive it, and I push on the pedal It will start to lose power. And miss fire 100%
Then, after that, when I disconnect cylinder two, it doesn't make any changes as if cylinder 2 is dead.
Everytime i turn off the car and turn it back on. The car is good again till i accelerate again on drive and misfires again

Obd2 works fine keeps throwing the same codes for crank sensor and can sensor. After replacing them both.

Thank you. My 2005 Corsa C will fire up but won't run go
for more than a few seconds. New pump, filter, 50 psi, new oil switch, new crank and cam modules, new plugss, removed throttle body and cleaned, maf cleaned...
But no fault codes either with pedal test or three obdii readers inc Xtool D7. I 'm suspecting a bad ecu. Your opinion pl ease!

Thanks, my car shuts off when driven and the engin warms up, at first i taught all kinds of things from throttle body to others fault, but the mechanic said its the computer box that faulty but the engine starts normal but cuts off on long drive
