Drain the marinade into the crock and add one cup chicken broth.
Brown the pork in the 2 tablespoons of oil then add the pork to the crock.
Cover, set on LOW (not high!), and cook for 2-1/2 to 3 hours or until the pork temps at 145F with an instant read thermometer. This might mean setting the cooker at 8-10 hours and turning it off after 2 hours 45 minutes if it doesn't say low already.
Remove pork from the crock and let rest, covered with foil, for about 20 minutes.
While pork rests, combine mojo ingredients in a food processor and puree.
