You might want to run some fuel injector cleaner in the engine and get some premium grade gas and see how it runs after that. I had that problem on my '99. Until one day I decided to let the truck run to a little less than a 1/4 tank, put 4 bottles of the STP Complete Fuel System Cleaner in it, and ran it for about 20 miles hard. It will puff black smoke and smell like a diesel, but that is the carbon and soot being burn out of the engine. After I ran it through, I then filled it up with Premium 93 Octane from a reputable Sunoco station.
Ran better than new and my mpg went way back up.
