[QUOTE="Zeb, post: 1528923, member: 30304"] Haha, me too! Anyway, now that I realize we’re talking about a 6.0, here’s something to check. Had a couple 6.0’s do what you are describing. On your drivers side positive battery cable, make sure the terminal is clean, tight, and in good shape, and also make sure the wire that piggy backs on is clean, tight, and in good shape. That is your main PCM power and if it is loose, or corroded, or has several wires under there and isn’t making a good connection, I’ve had them do exactly what you’re describing. Idle fine, but cut in and out, and puff black/gray smoke under part/full throttle. [/QUOTE]
