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

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.

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.
