Question for you guys just recently got a rebuilt titled 2005 f-250 super duty super crew 4x4 5.4 liter. And I need to fix some things before I can get it inspected here in PA . Gas gauge just says fuel level read error. Maybe sending unit? It stays on E. Then the airbag light is on. Says code 25 something withe passenger airbag? I don't wanna pay someone to fix this if I don't have to any advice would be great
