Our 2007 camry with about 130k miles is having misfire issue. I will post the freeze frames below to see if it assists. Ive been trying to decipher some starting point from it but am getting nowhere.

The car will shudder specifically when in gear, with the AC or power steering initiated. So typically under load, but also will intermittently do it in Idle under no load. When the RPM get to about 400 the engine chatters a lot and attempts to recover. Spark plug were replaced maybe 10k miles ago. along with the plastic connectors to the spark plug packs. No fuel injectors or coil packs have been replaced yet but may be the next step. Sorry in advance for bad formatting.

Thanks!

Swap out the coil on the No 1 cylinder with one of the others and determine if the P0301codes changes to that new location.
