Ignition Coil A Primary
I was getting a PO301 and a PO351 on my own OBD. I changed out that coil (Cylinder 1) and drove to AutoZone for a scan there afterwards. My car still misfired along the way and both codes still showed on their scan. I'd estimate a 15 minute ride to AutoZone if that matters any.
Just from checking the web it appears the 351 code can be multiple things but my findings have been vague. Also if I swapped out the coil why is that specific code still showing on both readers. It was an active code and not just stored I believe.
Any help is appreciated as I have off a few days and will see what I'm capable of doing before I put it in the shop again.

Somewhat recently I've learned this but now I'm kind of past that point. Last year around September area I had misfired and put it in the shop. At that time they only replaced two. I was told your all set so I left it at that. A month or so later more misfiring then I learned I needed 8 to update them all but the shop had no record of which two were replaced previously. So I had another swapped out and again another a month or so later. Then after more misfiring down the line I took it to MB but they said STS did something wrong on cylinder 1 so they replaced that one again. So I'm kind of stuck in a bad place. Since I cannot tell for sure which have all been swapped out. As of now I have 2 with black tops and 6 are yellowish tops.

The advice I probably need most beyond just eating what I've already spent and replacing all 8 at this point. Is if anyone has experienced the 351 code also STS, MB, and now I have all replaced Cylinder 1s coil at some point and still an issue on that cylinder?
Now I know how simple the swap is so I won't have to waist 100 or 150 at STS or MB respectively for their standard labor cost thus far.
Just in swapping out 1, I'd guess an hour max to do all 8 so I've been getting robbed lol

It appears the spark plug or wiring to the plug went bad. So Im going to replace that cylinder's spark plug. I had all 8 replaced last year but I was told the misfiring there over time might have made it go bad again.
