94 Dodge ram 4x4, runs super rough.

My old mac scan tool would work on the obd1. If you were north of the border i would send it to you to use.
In order for my newer scanner i would have to get an adapter off the snappy truck.


Should poke around the web and see if anyone is selling a DRB. That was the mopar dealer scan tool back in the day.
Have seen them come up for sale periodically.
