I''ve gotta small issue with an electrical outlet in my kitchen. I've got a GFI that is connected with two additional outlets as would be the norm. I was having a problem with the GFI popping every once in awhile, I replaced it with a new one. I am still having problems , it has popped without anything plugged into it, that I know of... I tighten all the grounds in my breaker box also, it didn't help

GFCI receptacles are polarized and connecting them correctly is critical. The hot wire should be black, blue, red, etc. The neutral should be white or natural gray. The ground should be green (if equipped).
Also, it's common to have other receptacles in a kitchen wired "downstream" of a GFCI so that if the GFCI trips or there is an issue with another non GFCI outlet, you're still protected.
Check all outlets in the kitchen and be sure they are wired correctly and in good shape. Unplug everything while you test. If the GFCI still trips, start looking for loose neutrals or bad ground wiring (or no ground) at the other receptacles since you said you already checked the breaker box.
A coffee maker can be a cuplrit that causes a GFCI to trip since it is a heating device and uses water, which can make them more susceptible to electrical problems. Check the microwave too (if equipped).
