Yep, it is rough. I dont know if it is just the V6. I rode an 8V AT but I dont remember if it was rough also. Mine is too. It could be the PCM but I have not seen a TSB for it. Also, I drove my father in law's 98 Ford F150 and it seem rough too, but not as much as mine. I had the truck looked over at the dealer for the rattle and they found the heat shield was loose. I still feel a rattle. Oh well, at least we have 7/70 just in case they are wrong.
