From what you are describing here, it sounds like you have a P0300-Random Cylinder Misfire. There are a few different things that can cause this. This can be the case of worn spark plugs, faulty ignition coils, clogged or faulty fuel injectors, an intake air leak, low cylinder compression, etc. Given the year of the vehicle, the best place to start here is with the spark plugs and coils. Remove the spark plugs and inspect them for any signs of cracks in the body and/or worn diodes. If there is any doubt, replace the spark plugs. If the plugs check ok, the coils will need to be tested to make sure they are sending spark to the plugs. If the coils check ok, then the injectors will need to be checked, an intake air leak test done, and ultimately, cylinder compression. Like I say though, more commonly plugs, coils or injectors. These engines aren't well-known for cylinder problems or intake leaks.
