Biggest mistake I see being made is cooking too hot.
I'm going to talk beef ribs because they my favorite....
Open a beer and take a generous sip every few minutes (this is important).

Leave the ribs attached, but cut through between each rib leaving about an inch and a half to two inches attached at the ends.
Start another beer....

Get a pot of water boiling on the stove (big one) and add about 3/4 of a cup of Worcestershire sauce, toss the ribs in the water for about 7 minutes with the heat on high. The water will stop boiling immediately.
Have the grill heating while doing this, shoot for about 400 degrees, as soon as your par boiling process is done throw the ribs in a large zip type bag (do not shake off or dry them) with some ground pepper, a little bit of Chile pepper, some garlic powder (fresh garlic is better but tricky to deal with) and a couple dashes of liquid hickory smoke, we use Wrights.
That's a lot of work, grab another beer.

Throw them on the grill and reduce the heat, typically one burner on low or near low. Grab another suds.
You should be seeing about 225 degrees. Flip them about every ten minutes cooking them for about an hour. Sauce can be added to taste at the end of the cooking process.
Enjoy with another beer.
Sweet potato fries go really good with ribs....
You can smell these bad boys cooking for miles....
