low torque and won't rev over 4000
Installed new long block in 1999 suburban but doesn't have power used to have, check compression all above 150. changed distributor, plugs. plug wires, fuel filter, checked fuel pump pressure well within spec even when driving, When first started will run fine good torque but still won't rev past 4000rpm when kicked down in passing gear, and if shut down for about 10 to 15 minutes has very low torque even when floored could fuel injector be problem they are orginial ones with over 259000 miles on them
