My check engine light came on. A mechanic friend hooked up his reader to the computer and said it was mis firing on # 7 cylinder. We changed all wires and spark plugs and did a tune up, but light came back on. He said I need a coil pack for it, but I needed to find out what the firing order was so I can install the coil pack on the proper cylinder, #7.
Can you help?
