Spark plugs, coils; any cracks on wires?

Cold is always a factor - moisture before it heats up and dries, also cold - switching from not running to running. 1st is hi rev. Have you read errors? Is it only misfire?

I would get out plugs and check if it dirty or something. Be careful with any cleaning stuff - it dissolves dirt and guess what happens next.
