misfire or fuel problem I am out of ideas
After searching and searching thru threads I cannot find someone with the same problem and as me. So I have a 2004 F150 fx4 with 5.4 with 130k on it. I was driving home the other day and stopped at a red light and my truck started trying to die and the light turned green and it had no power at all. I coasted to the shoulder and restarted the truck and I had power again. Got to another red light and it did it again. Restarted it but this time I slowly gained speed but could not go over 30mph. So I got home and pulled it in the garage and it would barely idle and when I would hit the gas it would bog out. So today I changed all the spark plugs and on cylinder 4 the spark plug was horrible. So I changed them out and still doing the same thing. But once I milk the throttle to 1500 rpm's it smooths out. So I changed the fuel filter still no change. No CEL or anything. Hopefully someone can help thanks.
