Default Throwing P0300 Code, please help!

I've read all the posts on this code and it seems like it could be anything (code is random/multiple misfire), so I'll just list the symptoms and see if someone could narrow it down for me. The car was running fine and I was sitting there letting it warm up (it was raining). All the sudden the car started running really rough and it started throwing ses light at me and the other engine light. It smells super rich (thought I had a fuel leak), and runs like general crap. Car has a hard time keeping idle. When it starts up cold, the car seems okay, but as soon as any load is on the engine, the idle is not holding and acts like it wants to stall. When I'm driving, there is a huge loss of power and does not run smooth at all. The ses light comes on and off also, especially under load. Any help would be great... thanks.

I also replaced the plugs and wires about two months ago and it ran fine untill last Friday... so I am assuming it is not the plugs or wires. I have heard it could be a bad relay, bad cam/crank position sensor, or O2's are bad. Any input would be helpful.

did your car act funny before, or did it just start running like crap all the sudden? Did it smell super rich?
