Hi sorry to bother you with this but I was hoping maybe you may have run into this before....My daughter has a 2005(built 07/29/04) 6.0,has 147000 miles,no modifications except for EGR delete,I purchased the truck for her in May being ever since she was 8 she wanted a Powerstroke,just replaced all 8 injectors,dummy plugs and turbo center housing all Ford parts done at a Ford shop which I work for.....truck runs great after work was done (5 inj were bad and housing was bad) but now and then since the work the wrench light comes on while still running just fine and will reset when truck is shut down and it comes on at random,doesnt matter if ran hard,long periods etc.,had them here at work check it out and they cant figure it out and also latest flash to pcm has been done.......any info or ideas are greatly appreciated!!! Thanks!!!
