Having problems with your 2004 Saturn VUE ?

Check engine light is on. Checked code, and it was P0300 for misfire. I changed the plugs and wire caps, still the same problem

Answers :

Replace coil pack
P0300 is for random/multiple misfires on all cylinders. There may be a vacuum leak into the intake manifold, a stuck or leaky EGR valve, low fuel pump pressure or faulty fuel pressure regulator, an alternator that isn't working properly, or a clogged fuel filter---there are more possibilities but they get pretty exotic.
