Its the gift that keeps on giving. Started my car with my code reader and now its running even worse, I got two codes P1000 which is normal and now a new one which is P0406. I did check my lower intake bolt and snugged them up they were too loose, and I was going to check my supercharger to Upper intake bolts but the fuel rail is in the way should have had those mechanic check them when they replace the injectors, but they didnt. I did find one that I could get to on the driver front and it is loose and must be stripped since it wont tighten up. I wonder if Ford did that when they installed the supercharger 4 years ago. I dont even know where to start with this thing now.
