Eric Will be doing just that for me one day soon i hope.. Dinoz just left here after putting some cleaner in the tank, so hopefully will see a difference next cold start (injector and carbon build up that is).....maybe :zlove: Cheers Patrick
Hadn't looked at it from that point of view. Had checked that the plug fired when cold and ran the engine for about 30 secs when cold, then took plug back out. There was no wetness (fuel) on the plug, so at that stage i didn't investigate PTU or wiring any further. (Running series 2 PTU) I had already swapped plugs and coilpacks around and the problem stayed at #6 cylinder. Have run some injector cleaner with a new tank of fuel, to see if there is any difference to cold startup over the next few days and won't have a chance to redo cold compression test until next weekend.
