Update:
Well I replaced the fuel filter, which after three years it needed. Overall the car has been running well although there is a slight occasional hiccup. This morning it ran great until I got halfway up a hill. Not a huge grade but enough to make the engine work a bit harder than usual. Anyway, It starting running rough, almost like it was starving for fuel. When I stepped on the gas it ran smoother but when I was trying to maintain a speed it ran badly, not firing on all cylinders. I got to my destination and back in my parking space still running like crap.
