Spark plugs and plug wires. Fuel filter and clean the Idle Air Control Motor. Also clean out around the butterfly in the throttle bore with carb cleaner and a rag. There should be a fuel pressure regulator on the fuel rail (where injectors plug in) unhook th evacuum line to see if there is fuel in it, if so replace the regulator, this is probably where your mileage went
