RE: TUNE UP COSTS?
not all that much really. spark plugs, wires, maybe coolant and trans if you are due. check a bunch of stuff. grease ball joints, check belts, hoses, maybe diff and transfer case fluids. don't know what the cost would be, but it will vary with how much you're getting/need done. the plugs and wires alone will run you over a hundred if you got them done somewhere.
