2004 f150 4.6lt Triton
My truck was running fine. Then coil pack
went out.. i have replaced all of them. Put
new plugs in. New fuel filter. Complete oil
change. Fitee breather filter everything. Even
a fuel rail cleaning. Still when its cold it runs
great. But after running for a while truck
shakes really bad. At idle shakes really bad.
Wont accelerate quickly power of motor real
low. Between 1500 &200 rpm bad shakes.
Over 200 rpm shaking stops but truck has
no power.. when warmed up sounds like a
diesel. Spent a grand now. Just got a new
brain box but still cant read codes. Please
help.
