White Smoke, Bad Smell, Misfire Code

I have a 2000 Volvo V40. About a month ago it was overheating, so I replaced the thermostat, which seemed to fix the problem. It has had misfire codes for about a month as well, and I haven't done much to address that problem. Today, white smoke poured out of the tailpipe for a few seconds on startup. It shook and vibrated a bit, and there was an awful burning smell from the engine. I really hope it isn't a head gasket. Any suggestions?

I would pull current codes, then inspect the spark plugs (they can be very eloquent), check the condition and level of engine oil and coolant (cross-contamination and/or fluid loss), and finally do a compression test.

In general, white smoke can mean either oil or coolant (depending on odor). By "burning smell from the engine" you mean from the tailpipe, yes?

Exhaust smell coming from the engine compartment? PCV condition, hose cracked maybe?
