Need to check the fuel pressure, at the Schrader Valve, it should be 56 to 62 lbs. This is just a start.

Since you didn't give mileage I am assuming it is considerable... If you still have the stock exhaust, remove the caylitic converter temporarily and see if the solves your issue...

Good answer Restorations, another way to tell if the cat is plugged is to drive the vehicle at night and get it warmed up good, stop somewhere dark with the engine running and look at the cat. If it is plugged, it will be from slightly glowing orange to brightly glowing orange. You can't miss it.
