It might make all the difference, actually.

How long has the driving situation been like this? No problems when you had the long commute? What plugs are you running? Have you pulled atleast one bank to read them (color of electrode)?

I would urge you to try out everything simple first, and that includes checking fuel lines like Dead Parrot mentioned, but also to not assume anything you've done 2 years ago is still like new.
