This question relates to the previous question asked. The second, relates to the coil packs.
The SHO is an 8 cylinder car. This question relates to the previous question asked. The second question, relates to the coil packs not firing on cylinders 3, 6, 7, 8. This does niot make since but it is true. The indiviual coil packs where checked I notice that coil pack #2 was firing however, coil pack 6 and 8 was not. I did check to see if the coil were good and both were good. so could it be the PCM problem. Becaues all the coil packs are not getting fire. the coil pack was changed about a year ago. Just to let you know I used the Motocraft spark plugs and the coil pack are new as well.
