Default Re: another p0300 question

I would pull the driver side fuel rail and check for water. It will pool towards the back and cause a number 7 misfire. Number 2 may be showing misfire counts due to 7 misfiring and not actually misfiring. If no water is present remove the injector and inspect the inlet screen for rust or contamination plugging the injector.
