Below will cause your problem:

1.Fuel pressure not within specs.Can be cause by restricted fuel return line or defective fuel pressure regulator.
2.Defective Oxygen Sensors.
3.Leaking injectors.
4.Coolant temperature sensor out of calibration.
5.Restricted air intake system.

If there's a problem with the plugwires it'll be misfiring and will take more gas to produce more power to move the vehicle.
