6.0 check enging light wont rev over 2k in gear

hey all,
i had an 06 6.0 in the past and have always wanted another one
today i went to buy one and the batteries were dead.
we jumped it and it now has a check engine light, the odometer wont display anything, until i do the dash trick,

it runs great idles great throttles up in park no problem.
when your driving down the road and step on it, it wont rev over 2100rpm????
no clue whats going on here. the previous owner said they just had the high pressure oil pump done..
is it starving for fuel?
it still runs fine, no smoke, but wont rev over 2krpm
please help/
btw its an 06 6.0 kind ranch
could this be as simple as not having enough voltage from the dead batteries?
as soon as i shut off the key and tried to start it, it was too dead to crank,
but atleast now the dash, odometer cluster works now
please help

Go read my post A Word of Caution under this thread, and don't jump it any more.

Dead batteries can cause all sorts of weird symptoms. Get a couple of new batteries put in there and see what happens.
