Edit: If you read my original post, disregard it. I misread the codes as starting with P03 (misfire) not P02 and posted my response based on that. Sorry for the mistake.
P02 codes indicate the fuel injectors as the problem. The most efficient diagnosis would be to swap the 2 injectors from the the faulty positions (cylinders 1 and 2) with injectors from 2 other cylinders. If the codes follow the injectors, they need to be replaced. If not, the control side (wiring and PCM) need to be diagnosed.
That said, I stand by my original recommendation to take it to a shop if you’re not comfortable doing this.
