Hey all with high miles 75k+ or so this just dawned on me. there is a product out there called "Restore." i think thats it anyway it comes in a can i think its an oil treatment it does unbelievable things. it completely restores power to at least factory and is not very expensive. it will increase gas mileage slightly. its just another suggestion for you all to try i highly recomend it. it did wonders for my car. try it tell me if you get any good results like i have.
