How long are your spark plugs lasting?

barely discolored plugs after use might not be a good thing. clean plugs could be a sign of an engine running lean/hot or coolant getting into cylinder and steam cleaning the plugs.

Your right. I bet the engine blew up!!!

Well, scratch the bad plug idea for my issue. Turned out it was a broken Air Intake Sensor that was causing the misfire code. Found it just dangling off the intake pipe. $14 dollars later, problem fixed. No more code.
