Let's start over......
Doug from Ford called... Need new plugs and atleast one coil. There were some bad ones. Looking at close to a grand if some break. He said its and extra half hours labor if one does, so $48. He had no issue with my maggie hi flows, but he said one might have been ruined due to the misfiring. I can just have my exhuast shop weld one in, hell at that point, I may even have a new muffler put in down the road
Right now at this point you gotta trust someone......
