i have gone through just about everything that this code could possible be caused by. at least that i think it could have caused this code to show up. my truck is running pretty bad like its not getting enough fuel around 3500rpms is when it starts. when i start it after it has cooled down it seems to idle right and when i give gas its good until it takes a load or when put into gear. then the check engine light flashes and throws that p0300 code. i have changed the following.
wires
plugs
EGR
IAC
CAM potion sensor
cleaned the MAF
changed out my O2s
fuel filter
ran injector cleaner
checked for vacuum lines for leaks
changed put fuel pressure regulator
made sure that i had spark from the coil pack each one seems good
HEEEEEEELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
