battery causes p0300 misfire?

[rasczak]

can a battery cause a misfire in a 2003 mazda6 v6?

Low voltage certainly can cause misfiring.

I think we would need more info.

Highly unlikely. That means NO.

If the car starts and run it isn't the battery.

I've replaced my battery. Needed to be replaced anyway. the issue I'm experiencing is more of an annoyance than any real issue. every so often the car spikes in idle and while driving it does a slight lurch. I was incorrect about the code, it was actually a p0301 code. I know the car is overdue for new plugs so I'm going to change those and take a look at my vacuum lines.

#1 cylinder misfire.
302=#2 cyl misfire
303=#3 cyl misfire
300 is a multiple cylinder misfire

Plugs, plug wires, coil packs...

Those are your likely suspects.

COP (coil on plug) ? If so, multiple misfire is going to be ignition controller (ecu) or crank position sensor. Lucky you it's only #1 it seems. Swap the coil with another cylinder, reset code, see what happens. Chances are it wil go away completely just from messing with it.
