Yes. Bad, clogged, or stuck fuel injectors can do it also, or one or more a bad injector O-rings. Misfire is not always spark related. In fact, I have a shop pulling and flushing my injectors now for misfire codes, and it's not the coil packs or plugs (or the voltage converter either).

I get a transient P0300 with a P1170 and a P0422 mostly when I use discount gas with less than 92 octane. Engine runs fine but she will throw those codes and set a yellow check engine light. If I use a bottle of Techron and brand name premium gas, the CEL turns off. I can also simply clear the codes but they will come back the next time the gas is crappy.
