4age 16v running roughly - diagnostics shows unknown code

[Ryo]

Hello. I recorded video what is exactly my engine doing. I hope someone can point me in direction what should i be looking at next. I was still not able to locate the cause. I am replyiing a little late as i catch bad cold but now i am fine and can continue with the repairs. I can now smell more gas from the exhaust as before. Maybe because it is getting colder and i am repairing the car outside as garage is occupied by other car currently (not too happy about it as it is getting colder).

Thanks Jondee for taking your time to help with the analysis. I really really appreciate it :-)

What you mentioned i will try as next. I got fuel pressure gauge so i will need to hook it up as manual say and test the fuel pressure. My fuel filter was not changed for years i think at least from 2005 when i buyed the car i have not changed it but i buyed new one from toyota already as i wanted to do so this summer but got no time to do it perhaps now it is a good time :-) I remember that it occoured some months back while driving on highway the car suddenly started to hesitate to accelerate this occoured 2-3 times. I was thinking bad fuel as well that time so i changed the gas station and after that no more issues. But this time i was putting fuel there as well on different gas station maybe they got water inside the tank but i am not able to tell this only way to do that will be drain the tank and i am not sure if i will be able to unscrew the bolt on the bottom (still using the original tank).
I am always using 100 octane ( 98 ) fuel now (E5) as i dont want to put E10 fuel inside.
