code P0300 Random Misfire backfiring, cutting out
So among the other list of problems ive dealt with this past winter, heres another. Cuts out like CRAZY, backfires and has crap for power. It jerks and chugs, the whole shabang. This is where it gets confusing. I have a 2002 5.4 running off of my 99 4.6s coil PACKS, 2 of em. They, unlike the motor and everything else ive already replaced, has 330,000 miles on them, yep they are origional.
I did do a search, and i read that it may be a lean code? As far as fuel injectors, BUT im not getting a specific cylinder misfire code, and my SES light is not flashing (misfire). As far as i know , coil backs just go out, but i would be throwing 4 misfires wouldnt i? Is there any such case that it may just be going out, 1 cylinder at a time? I am stranded now, with no way to work so, anything you guys gotta say will be much appreciated as usual
