just bought a propane truck, it sputters when on the highway...
hey guys, i recently bought this truck to just haul stuff around it, it runs on propane, it sarts and drives fine, but when you give it more than 1/2 throttle or take it past 50mph it starts sputtering. the prev. owner told me its some filter that needs to be changed... i've never dealt with propane do i dont even know where to start.... What should i check and replace?
