Question about Chevrolet Impala
It sounds like a bad injector or a bad fuel pump .A p0300 is a random misfire.The best way to find out what the problem is take your car to some shop like Pep Boys or someplace equivalent to that a have them do a complete balance test of your injectors and have them test your cam position and crank sensors both of these sensors can be tested for proper operation.Ask them for a computer read out this will tell your mechanic exactly whats wrong.
