At random my car will misfire and through a p300. I have sent all the injectors in to be checked. They checkout great. I replaced all the coils. All cats were replaced. I replaced the crank sensor. I also replaced the fuel pump and filter. I also put an 2004 rear valve cover on to fix th 2003 oil leak. When the car is running fine the output voltage is 14.1-14.0. When it is running rough it drops down to 13.7-13.6. The mass air flow sensor is also new. Running out of options.
