Your fuel pressure regulator could be stuck closed. Your computer should adjust the injector pulse width to fix it though, but it might be worth checking out since all you have to do is pull the vacuum line off of it and watch the fuel pressure. It should go up. If it doesn't it is either stuck closed or your return line is clogged.
I would still get a tune up though, it could help. Engines with that amount of mileage on them could easily be worn enough to have poor effeciency.
