P0300 Ford - 2006 expedition

Question

I have a 2006 Ford Expedition with 197, 518 miles on it and the check engine light flashes on and off never staying on. All plugs and two coil paks were replaced so what could be the issue that keeps throwing this code at me daily? I checked gas/ air lines and connections going to plugs and injectors and found no leaks of any sorts. Help!!!!

HI there,

This code could also be the result of low fuel pressure, internal engine issues or a problem with the mass air flow sensor. The multiple misfire code can be difficult to diagnose. With what's been done so far I would check the compression on the engine to be sure its not the issue.
