obd reader
I just went from a 1972 f250 to a 2004 f250 superduty. I'm contemplating buying an obd reader. Are they worth it? Which one should I get? How specific is the diagnosis?
I'm used to doing most of my own work, but when I popped the hood on my 2004, I noticed the engine has a little different apearence than my 390. I'm scared!!!!!!!!!!!
thanks,
dan

There are lots of levels of OBD tools. In rough order, the read trouble codes, clear trouble codes and check engine light, can read data, can read freeze frames, can graph data over time, can command controllers, initiate tests. Another level is whether the reader can only read generic codes and data or includes the proprietary codes and data. Powertrain codes start with a P0 or P1. P0 is required by EPA and any tool can read them. P1 codes are added by the manufacturer and you have to have specific software for each manufacturer, usually Ford, GM, Chrysler (or combo pack for all three), Honda, Toyota, and Asian combo packs, and Euro combo packs. Then the ability to graph data over time. It can get pretty pricey. Finally, most can read the original 3 OBD protocols but the new CAN protocol is coming and some will read it too.
I would recommend getting a code reader that can read generic and Ford codes if you are in the ~$100 range and move up from there.
