Check engine light is on getting a code P0300 Random misfire. I have change spark plugs and wires. Change fuel filter checked vacuum lines, ran fuel injection cleaner through several times and light still on and still getting a code P0300. The truck shows no signs of a misfire runs fine the only thing I notice is when the fuel gets low you can really hear the fuel pump and it sounds like its struggling then after you put fuel in no more noise. Help pulling my hair out
have the same problem?
