Fuel consumption is the same going down the road on trip... what needs changing...?

well if you dont have a check engine light on, you may have some very simple problems. I would start by doing a throttle bore cleaning, and take a look at your idle air control valve. you may also try changing the pcv valve and mapp sensor, I am sure this regimen, will clear you right up. keep me posted. these are all simple things you can do to keep your vehicle running smooth, also do wires and plugs if you havent yet.
