Throw a chunk of bad wood and you get yellow smoke. remove food, remove the bad chunk and wait for bad smoke to get out of system and try again. Yellow is resin burning out of wood (wood was not aged correctly.)
Gray/Black smoke - Grease fire.
Watch a video on the tube of how to home make charcoal and most will show the wood gas burning off and many show the yellow resin smoke too.
This is good information here. Well said. And to carry on to what someone else mentioned earlier about coal tasting. If you do not like the coal taste, try switching what kind of charcoal you use, especially going from briquette to a nice lump charcoal, big difference in flavor, and it also cooks differently.
