I don't know if this may improve your problem. But, my SAAB has been running much better, then when I first bought it a year and a half ago when I cleaned the throttle plate. I sprayed it in almost every orifice I could reach in the throttle body. It accelerates great, runs much more smooth. I know the EDU computer doesn't calculate MPG very well, but mine jumped from a HW MPG of 21 to 27. I don't know if the absolute numbers are correct, but I'm sure the change is accurate (assuming both readings are equally off the mark).
