Thinking about buying 99 diesel... What to check?
Ok so first off i will admit i don't know anything about diesels. i went and looked at a 99 f250 diesel tonight that seemed to run great and rode smoothe. He says it has a 6 inch exhaust and tune, but all he showed me was a little dial and said that controlled idle, boost and had settings for towing and fuel economy and performance. Is this possible or is this just a simple boost controller?
Also what should i look for wrong with this truck. It has 180,000 miles it is a 99 f-250 7.3l 4x4 extended cab truck
