Oops, lost my post.

I'm throwing in the towel and taking it to Surgeline in PDX, OR area. They offered good advice of what to do by swapping parts instead of throwing parts at it if I wanted to do it myself. I really appreciate that. But they are much faster than I am at this work so I'm taking it to them.

They advised coil swap, plug swap and port injector swap for troubleshooting to see if problem follows a component. And stated that is where they would start their troubleshooting. I asked if taking a log would help, they said no. I was a little puzzled, but they said it'll just show us the code, not the signal of what's causing it. So no need for a log, but I sincerely appreciate the offer Poogchomp.

But this service also gets me at the shop to talk some more details of improvements to come. I was thinking of getting a tune up service from them and a new tune on the SC system. And at this mileage, I want to replace the coils and start going for the suspension bits and alignment. I have LCAs in a box ready to go, eccentric bolts are in the front already from a previous alignment. Then I threw this code.

Not bad overall with this car, 108k, with an SC since 85k. This is the very first CEL issue, and it's not an O2 sensor Car's been paid off for a long time, mostly fuel, tires and oil have been the brunt of the cost of ownership now. I'm hoping for a just a plug swap for root cause as antifreeze and oil do not show signs of head gasket issue. I've run 2 tanks of injector cleaning products and no change, same P0301 pulling above 6k. It started at 7k and seems to be slowly creeping down into lower rpm ranges. Maybe the cleaner is just cutting more junk loose, not sure. I wonder if they'll borescope the chamber being we all know a sparkly clean chamber is not a good sign for the wallet.
