Hi James, Could you re-iterate how you connected the new OBDII port? I have the same thing (OBD device but nothing being read) and would be keen on adding this mod to be able to read any errors from the ECU

Hi Philip, Did you get to the bottom of this and fix the misfire? I have a similar problem with my R300 duratec. It started after a particularly long (and fun) blat out for 9ish hours followed by a track day. I've swapped all the spark plugs for new ones but the problem is still there. My plan is to get new coil pack and swap each one out individually and take it for a run to see if it fixes it or not. I already have the upgraded coil sub loom and the cabling looks sold into the coil connectors so I don't currently think it's the sub loom. Thanks, David
