I have moved from dallas,tx to pagosa springs co. my truck runs fine.. Its just has no power up here. the elevation is 7000+ . I have no horse power. Never had this problem in texas.
What would give me more power? hotter plugs? new truck?
really love this truck it has 131,000 its a 5spd 4cycl. idles fine and runs fine. Just no power in the moutnains..
