Same code came back on

Question

Hi, i have a 1999 toyota camry 4 cylinder, and I had error code p1300 and p1310 come up. I changed the ignition coils already (new parts from autozone), i changed the sparkplugs before i changed the ignition coils and i changed the wireset when i changed the ignition coils. My car ran fine for about 2 days then the check engine light came back on and it gave me the same error code, what do you think it might be?
