could it be the gaps in the spark plugs ?
or ur 02 sensors or ur fuel injectors, also check ur vanos solenoids and make sure ur cramshaft position sensors and wires are good and intact and make sure u have no vacuum leaks. those are the only causes i can think of. hopefully this helps

Excuse the newbie question, but shouldn't he be able to see most of what you mentioned through additional fault codes? (depending on the OBD2 reader, of course, not all of them detect vacuum leaks).

Assuming that he had no other codes, could it also be some water in the gas tank and, if so, what diagnostic steps could help to determine if that's the case?

PS:
I'd be curious to see how the OP resolved his problem
