2002 Ford Taurus 3.0L OHV: Only half of the cylinders firing
On my Taurus I hooked up a timing light to tell if the plugs were sparking and plugs on cylinders 4,5,6 are working great but cylinders 1,2 fire less often than they should and cylinder 3 does not fire. But its 3 coils shared on 6 cylinders so i swapped the wires to the ones that are on the same coil and then cylinders 1,2,3 were not firing right but 4,5,6 were firing great.
I've replaced the coil pack with a new one and its the same story.
any help would be great
