In a large bowl, whisk together barbecue sauce, apple cider vinegar, brown sugar, Worcestershire sauce, chili powder, smoked paprika, garlic powder, onion powder, cumin, salt, and pepper. Set aside.
Preheat the grill to medium high heat (around 350°F). Place pork shoulder in a grill safe dish or aluminum foil packet.
Pour half of the sauce over the pork shoulder, reserving the remaining sauce for later.
Grill the pork shoulder for 2 hours, basting it with the reserved sauce every 30 minutes and turning it halfway through cooking.
Once the internal temperature of the pork reaches 195°F, remove from grill and let rest for 15 minutes.
Shred the pork using two forks and return to the grill for an additional 10 minutes to reheat.
Assemble sliders with pulled pork, coleslaw, and top with the remaining sauce.
