Car posting code P0172 S90-V90

Thanks Dewfpo-I reset the code with my new toy(actron scanner) and the light is off now. What I'm trying to figure is the ready and not ready codes from the emission system-this is the same thing that Lawunion is batteling in one of the posts below. The ignition, fuel and compression codes all read ready but the rest of the codes 02 sensor h02 sensor cat and egr (which there isn't one on this model) along with the air pump all read not ready. Now I don't have to contend with the state of Va on emmisions on these points like Lawunion does,but I'd just bet that some where in the middle of all this is the 3-or 4 miles to the gallon thats been missing. I don't know if the purge valve could have caused the problem but will be checking in the future for sure.
Thanks Poolman
