Default F150, bogs down at 55mph 1300rpms
So I've been having this weird issue lately with my 05 F150 5.4. It's been going on for a few days now. Everyday I leave for work she'll start up nice and fine, idles smooth at around 950 rpms. Ones I get going for the first couples miles it'll shift smoothly and all is well but once it shifts at around 50-55mph at around 1900 Rpms and drops down to around 12-1300 Rpms after say 5 miles or so, it sorta bogs down like it wants to stall. And it'll continue doing that until I get to where I'm going and turn it off. Then it's the same issue over and over again. It almost felt like the same issue I was having when I replaced the vvt solenoid and cam sensors. But this time it just feels like it loses power and doesn't want to go anywhere. But if I lay on the gas a little it clears up and goes. Doesn't hard shift or anything. Could this be a plug or coil issue maybe? Or maybe a plugged converter? No CEL or codes popping up either. Does also have a slightly rough idle after driving for a bit.
