I have a 95 lumina ls with 83000 miles and the 3.1 v6 with everything bone stock. So with my lumina I am getting like 23 highway and 12-13 city. I dont drive the car rough it has good plugs and doesnt seem to be loosing any power or lag at the pedal. I know it needs wires just havent had the time to put them on. Do anyone know that the plugs should make that much difference? or if there is naything that I can check.

Thanks
