i have codes that are all dealing with misfiring on 1-3-5.  i did a tuneup on it.  i light goes out, i drive it for a couple of days the light comes back on reading misfiring on a different cylinder.  it is always on that side of the cylinders.  It came on again today it reads misfiring on cylinder 3.  I have done tuneup after tuneup, change sensors, changed fuel injectors, can any one please help me.

  1. Most common causes would be a vacuum leak or a sticking EGR valve.

    Post the code numbers if you have them handy….

  2. first time it was p0300, p0301, p0303, p0305. Now it reads p0303

  3. I would start with EGR
