    Trading the Expy...

    So the time has come where I can't justify spending the gas to keep this truck on the road. I'm sorry to say that after 6 years with the truck, I'm trading it in for a GMC Terrain. Just want to say thanks to all the members on this forum. You have been a big help over the years with your...

    What can I do with a USB-to-OBDII connector?

    I've got a computer mounted in my '03 Expy w/ 4.6L currently with a touchscreen LCD. I'm thinking of getting a USB-to-OBDII cable, but I'm not sure exactly what all I'll be able to do with it.
