thanks for the info. checked out dieselstop.com after viewing a link with fault codes listed there and some folks are having the same thing happen. seems to be the consensus there that it is the ficm and there is a recall on some vin #s for the 6.0.
Can auto zone pull the codes and i can...
A couple of months ago my 06 F-250 started running rough when cold. once it was up to operating temp it would be fine. the problem was variable for a while. the check engine light came on a couple of days ago and it had noticeably less power under accel. any suggestions?
