Rough Idle and when Running

Rough Idle and when Running
Can someone please help me! My truck, for the last 3 months, has been giving me fits. When I start it in the morning it runs about 1400 RPMs then after 8 seconds drops down to about 400-800 runs really rough ,has died, then starts back up and runs fine. Sometimes it runs fine after I restart it sometimes it doesnt. It shows pending codes PO353 and PO357 everytime and sometimes has up to five of these codes at once. Ive taken apart the coil pack harness and cleaned, replaced all spark plugs again, changed all COPs and tested them again all within range, and put dielectric grease on all boots. I dont know what is causing this and have no idea where to go next. Any ideas, help, or theories would be greatly appreciated. Thanks

Ive cleaned the MAF twice didnt make a difference, gonna clean the IAC this weekend. I put the dieelectric grease on the connectors, and tip of COPs. The codes are P0357 primary/secondary circuit malfunction

Swapped injectors this weekend didnt help, have swapped around coil packs no help, cleaned MAF, replaced fuel filter, cleaned harness pins from PCM to coils nothing has helped, anyone had anything similar? Could really use some help!!!!!!
