I replaced sparkplugs to solve a rough idle now i"ve got that plus a severe lack of power.i"ve had it scaned twice.and replaced the massairflow sensor ,throttle position sensor ,and fuel regulator. I am also on my third fuelpump in two years! the truck acts as though the timeing is retarded when off idle. being a 5.4 i do think i could have scrued that up!
