Hello,
I searched the forum for this topic and came up with nothing relevant to my current situation. I recently installed a Mountune FMIC (no issues), however, today when I went to install some NGK plugs, I was greeted with the check engine light. I ran the Cobb AP read code and was given "P04DB." I searched that on the OBDII diagnostics code look up and it says "Crankcase breather system disconnected." Where is that located? Does it have anything to do with disconnecting the MAF sensor on the intake when I was getting to the plugs? Additionally, car was sluggish on first start after changing plugs. And again after returning to OEM plugs. Any help would be greatly appreciated. I've had this car for all of two weeks and am hoping I haven't screwed something up too terribly. Cheers.
