I have a friend with this truck that just seems to have a mind of its own. SOmedays it runs good others it doesn't have enough power to get out of its own way. The ford dealership and the local transmission shop haven't found anything wrong with the transmission or engine. The truck is off warranty and would like to find a simple fix rather than putting a new computer; if that is indeed the problem. Lately he has been blowing fuses also. Has anyone out there had any troubles similar to this?? What could it be and how can you fix it?? THe computer says there is nothing wrong.
