i have a 2007 saturn veu 3.5 engine i have misfire a random with codes p0300 p0301 p0304

Answer 1

Hi there,

You also have a the codes P0301 and 304. These mean cylinder 1 and 4 are misfiring. This will bring up the P0300 code as well. I would start by changing the ignition coils for the cylinders that are misfire and then clear the codes. Likely none will come back.
