help with P0351/356 codes

I bought a 04 FX-4 a couple months ago with 102k on it. Brought it back to selling dealer, they replaced #1/#6 coils, its ran great till this past week. Again it has stumbled a couple times this week. It only seems to have the miss at idle (comes and goes) take off from light, within 50 feet its running like a champ again. I cleared the codes (disconnect battery)and now it seems my idle is not steady, it fluctuates. Any help with the codes, is the idle a product of the codes?

These are coil primary codes. Make sure #1 &#6 coils are plugged in all the way. You may have a wiring issue or faulty coils.
