Hi all. New member to the forum. I have a 2001 Disco II that's been around with me since 2004. Rebuilt the upper end with no problems. Just posted specifically under Discovery II forum regarding an in OBDII code that stated a 3-7 cylinder misfire but they appear to be firing fine and engine running smoothly. Ran the code due to extremely poor gas mileage and poor engine response. Looking for folks who may have had a similar code readout or what else could cause a code like this to appear.

thanks
