I drive for a living and work on my own vehicles. I deliver the US mail on a contract basis on the Crow Indian reservation in MT. I have known about OBD II since it was the law...I have had a few '95 Subarus and they had it. My current vehicles are a 2001 Ranger with 231,000 miles and an '05 Explorer.
A lotof shade tree mechanics are afraid of "computers" but I love it, I just figure it's there to help if I learn to use it to it's full advantage. I have done some hacking and cracking with OBD I but not the second generation...yet!
