Default Engine misfire on 5.4ltr

Ok so I replaced all spark plugs and coil packs on my motor. Truck ran great for 4 days. I pulled up to a customers driveway and my truck starts to misfire at very low rpm. I accelerate a little bit misfire goes away. After messing with it all day yesterday and not being able to verify the problem I took my truck to an autoparts store to scan the computer. I am throwing the following codes p0351, p0352, po357, p0358. Now all these coil packs and spark plugs were just replaced 7 days ago. Any help would be greatly appreciated.
