    Had this code show up after the warning light came on and then the light went away after two day, the car seems to be alittle sluggish now. I have read that this is a random engine misfire and it could be a bad plug anyone else have had this problem

    Yes, P0300 is a random misfire code.

    It could be any number of problems. Here's some info.

    This PDF is a great resource, thanks for posting. Any idea where I could find the full manual that this is taken from?

    Thanks!

    Looks like you have an 07 but are researching in the Gen1 forum. Make sure you get a service manual for your year. The codes mean the same thing, but the service procedures may be different.
