ok on efi please do not hold the pedal down.. ok with that said how cold are we talking here? florida cold or michigan cold. and the next question i have is have you pulled the codes from the computer yet?

lol, not holdin it down like with a carb, i gotta hold the pedal down a little 2 get the idle over a grand long enough for the idle to smooth out. and i live in New England, eastern CT so some times its realy realy cold -5 and some times its just chilly, 30ish. and i dont know how to pull the codes.... do i need 2 buy a tool?

yeah ya do run to your local auto store and ask for a ford code puller or check your local wal mart for them

your tps could be giving you fits

it seems that a new timing chain has cleared up the problem.... a "simple" waterpump replacement revealed the timing chain was, past its prime, and the truck starts much better now.
thanks
