Verifiedhello, my name is ***** ***** I will be glad to assist you. please allow me a couple of minutes to gather some basic info.
Roy
ok, the first thing I would do is check the fuel pressure. low fuel pressure is the main cause for the 300 multiple miss fire codes

Customer replied 6 years ago
Good day Roy. Realized I could use my iPad OBDII scanner to read fuel rail pressure, etc. the first attached picture is at idle and after warmed up and it's at 54.8psi. The second picture is driving at 3k RPMs and it's at 57.4psi. The last is while driving at over 5k RPMs and right as I again received the P0300, etc. error codes and it's at 51.3psi.
please take a moment and rate my service. it is the only way we get paid for our efforts.
