Hi Rarbolay,
I would definitely put an 100uf @ 16 volt electrolytic cap on the 3.3v DC rail, as near to the ESP8266 PSU connections.
Good you have serial communication, so at least you can see what the code is up to.
I don't have any pullup resistors on mine and works fine, you could try two 4k7 pullup resistors on the I2c bus this may help.
let me know your progress.
