Okay so I used 16oz of corn syrup on 5 gallons on what beer. Too much and will my bottles explode if I cap them?
Yeah you used way too much. And Yes, if you cap them they are likely going to explode. I would let it ferment out and re-prime.
How long should I let then go until I can referment them?
Like I said, I would let it completely ferment out. Then re-prime and bottle. Here is an excellent site for bottle conditioning:
