My check engine light comes on when driving sometime and goes back off. I got advance auto to read the codes in my computer the codes or PO118, PO128 the engine is running okay. Will any of these codes cause low gas mileage or the engine to burn more gas? What I have to do to fix it and what to check?

The p0128 In a previous post I posted to you that it was a bad thermostat and it could effect fuel mileage, not a lot but it can.
