I bought my 87 s10 4x4 2.8lback about 6months ago & this past month it has been driven the most all new shocks & all new brakes suspension, axles the whole nine & a fresh rebuilt 700r4 tranny. it broke down & turned out a 15amp fuse blew that was for the ecm & after replacing this fuse it started up it now has a real rough idle when 1st started in morning then after 10-15sec it levels out great & drives fine new tranny works great but it doesnt have power for nothing i cant go up like hills & whatnot over30 there is no power in the engine i changed filter, oil&oil filter cap&rotor, plugs&wires replaced some vacline that were old - the fuel filter/pump in tank i tested & is pumping normal not sure if its the engine which i was told doesnt have but like 60,000miles on it & dunno if it could be a bad computer in it or something with wiring that it'd blow fuse
PLEASE HELP ME!!!!
