96 gmc sierra 5.7 surging at cruising speed.
it is a good running truck otherwise, The associated code is a p0300
it is wierd only on the freeway will it do this, on bumpy country roads at the same speed it is fine. i have replaced the fuel pump, fuel filter, plugs, cap, e.r.g., and rotor. it runs better but still has the surging problem.
