1999 f150 firing just on 4 cylinders..
Hello to all, I hope that you are well, I am well but am in full transformation of the house this hard but great.
I post for a friend who have a 99 f150 5.4L 4x4 and he has some engine problem. The engine starts but run only on 4 cylinders.
Cylinders 1,2,3,7 are well but 4,5,6,8 make none glisten. Apparently the carburation is good.
They changed the complete plait of ignition, 8 spark plugs, 8 ignition coil, sensor of camshaft and brace but nothing makes for it.
Would have you an idea for helping my dear friend..unfortunately he don't speak english...
