Yes, P0300 is the "Random/Multiple Cylinder Misfires" code.

If you are asking what is causing it we need to know what year/model/engine.

Check your spark plugs or better replace them with champion or ngk double platinum.

Checking back on andrewhiler76's post history, it appears as if this was a problem about 2 months ago. Joel (aka rodeo02) suggested checking spark plugs and also to check to make sure the timing is correct, since this problem seems to have started after a timing belt change. I guess it either didn't work, or he didn't try any of the suggestions.

I know this might be a stab, but what about the coil packs on each plug? (Assuming 3.2L '98 or later)
