"I'd love to be hitting the "mountain trails" out here but I can't shake the P0300. I was hoping it was just a symptom of geography change but nothing. All the plugs, wires, coil and injectors all have less than 7000 miles on them. Chasing gremlins in 85 degrees and 70% humidity is getting old. I know poor me."

p300 is pre coils fault. Have you checked for dealer reprograms ?
dealer won’t even start to diagnose a problem till they run a reprogram to current standards..
