2006 f150 coil pack?mechanics step inside.
My son's 06 5.4 started running rough. Plugs only have about 10k on them. Code reader showed #8 coil pack, he changed it and did not help. Changed that plug and still bad. Took it to local garage, $35 to tell him #8 coil pack. He advised the mechanic of what he done, he said it was a bad coild pack. Traded it, and still runs bad with code. Any suggestions?
