If you can swing it, try to remove the marinated pork chops from the refrigerator 20 minutes or so before grilling and just sit them on the counter. It's always best to allow the meat to warm a little out of the ice box before grilling so that the meat cooks evenly.
Now preheat your grill to medium heat.
Shake off as much marinade as you can and then place the pork chops on the grill. There is a lot of sugar in that marinade and sugar burns, so don't go anywhere, be vigilant from this point on! After about 2 - 4 minutes, turn the pork chops to create those ever-important (to our egos at least) grill marks!
After an additional 4 minutes (about 8 minutes total per side, but just keep lifting the pork chops with tongs to ensure they aren't burning), flip the chops over.
You know the drill, turn them after about 2 - 4 minutes and continue grilling your pork chops until they are done. How do you know? Well, that takes some practice, but they should be relatively firm when you pick them up with the tongs. Until them, you can always use a meat thermometer...
Remove your grilled pork chops from the grill, wait about 5 minutes to let the juices settle and then serve!
