#1 cylinder misfire could be a lot of things and maybe it won't happen again. Bad gas could cause it, an intermittent fouled spark plug, or even a weak coil on that plug. The most common cause are spark plug wires, which the Crossfire does not have.

If it happens again and you get the same code, pull the spark plug and see what it looks like. Maybe you had a piece of carbon on the tip momentarily to set the code.
