P0300 random missfire

[shyrox]

Hello DSMERS, it seems like I've been having bad luck with my DSM every other month some new problem when i don't even drive fast. Well i wanted to ask if ya'll could help me with my P0300 code. The car sounds bad turning on and it has a really slow take off. Once i take my car keys off the lights on the dashboard stay on at low Voltage and they won't come off until i remove the battery. I hope you guys could help thanks

as far as the dim dash lights go, sounds like a bad battery/alternator...the random misfire could possibly be caused by a combination of a bad battery & alternator but not limited to, as other things could be wrong, ie; crankshaft position sensor, coil pack, or poor communication between the ecu-crank sensor. get the battery & charging system checked out, for starters, then go from there.
