Change the gas or add a octane booster. Also check your fuel filter.

Its more likely a miss.

bad gas.
dirty injectors.
dirty fuel filter.
dirty maf.
wires touching a header.

Did you get it fixed? I think mine is doing the same thing. I've changed the fuel filter, put in some injector cleaner, made sure all my wires are connected, and my plugs are about one month old. I just got a tune about 3 weeks ago and it's been running great, up until Saturday.

I triple check the spark plug wires, and took it with a friend and he check the same plug wire and discover that one of them had a crack and the spark was hitting the header, I replace the wires and LIFE is good again.

Did it run rough the whole time or would the problem come and go?

First was between 1500 and 2000 RPM then it became worst the whole RPM kind it like it was missing fuel. I would change each cable for any cracks on them before you move to something bigger. I also clean the MAF sensor.

ok cool, I'll recheck my wires when I get home. Hopefully that's all it is...I'm crossing my fingers.

If one is, best way to get it off the header is to spin the boot that is attqached to the coil until it comes off the header.
