Make sure all your wires are on the spark plugs. I had the same problem and only turned out to be a wire popped off the plugs. Then again it could be a number of things.

i had a problem with my car randomly started popping, driving it hoe from where it started this it started to misfire real bad, ended up being an 02 sensor but id check everything, pull a plug take a look. Check fuel pressure. I also had a lower rpm misfire problem once which consisted of my opti arcing off in the cap. Missfires are always a broad subject kind of sucks, need to just look everything over real well.
