i am getting only 17-20 mpg from my 92' Saab 9000 2.3 cse and garage put engine management system on check. It reported everything ok but need need Direct Ignition unit. Can anyone explain to me the way it works and why exchanging this unit would improve my fuel consumption. Does it need to be new or will a seconhand one do ? TIA jim
