Re: 91 s-10 putters on highway
no I did not change out the computer. What would that do and what do they usually cost? I noticed when going up hills it really putters, idle is ok.

Shouldn't need a new computer unless you went to a different motor from what was in there. (IE, going from a 2.5 to a 4.3)

Sure sounds like low fuel pressure. Change filter then put in a new fuel pump if still acting up.
