Hey guys,
My 90 gt acts as though it wants to die at around 2500 to 3000 rpm after it gets warmed up to operating temp. I have changed the fuel pump twice, filter, plugs and plug wires to no avail.
Any help would be greatly appreciated.

Have you replaced the fuel lines yet? Over the years, contaminants will coat a fuel line similar to what happens with sewer and water lines. And your veins if you love good cooking. It could be starving for fuel.

Remove the fuel tank, and do a good washout to clear any junk in there. Then replace the fuel lines, either with hard lines or with hoses. Try going about 1/8" bigger ID
