2002 Volvo s60 T5 Misfire, camshaft position sensor, mass airflow sensor

Hi everybody. I don't understand what happened. Sorry if I couldn't explain it properly.
So, I had replaced a Camshaft Exhaust Solenoid (it was my fault that it broke down). Due to a bad solenoid I had misfires, the timing belt was ruined.
So I got all of that replaced, put in new coils, new timing belt with all the tensioners, new water pump. So after replacing all of this, the car is running nice and smooth, no problem for about 2 weeks.
Now the Check Engine light goes on again, i got it checked and it shows random misfire on all of the cylinders, camshaft position sensor, and mass airflow sensor.
But the car is still running just fine. I don't feel no misfire, no shaking or idle. Nothing change with the driving.
Why am I getting all these codes and a Check Engine light?

Punch it to the floor, does it rev up like it should?

You are chasing multiple problems

A bad cam solenoid won’t usually cause misfires,

How old are the plugs and coils in miles and time?

I don't think it is a misfire. And Yes, it revs just perfect.
The car is 16 years old, I just replaced the coils, and I'm about to replace the spark plugs.
But that's not the problem. There is no actual misfire. I think its some kind of electrical problem. I think.
