What do the following codes mean for a 2006 scion xb p0300 p0302 p0304

Question

What do these codes mean separately or together?

Answer 1

HI there,

The code P0300 is a multiple misfire code. This means the engine is misfiring on more then one cylinder.

P0302 means it's misfring on #2 cylinder, P0304 means it's misfiring on the #4 cylnder.

Most often when you have codes like this it indicates somehow the timing is off, however a bad ignition coil would also cause this
