having a problem

Hey guys, just another issue I'm trying to figure out on my 98 gt. Ok so when I'm in first or second gear everything is fine but when I punch it in 3rd or 4th I get some vibration and the car feels sluggish, only when I floor it though...it almost feels like a fuel delivery issue but why only in the top gears? It's definitely not the clutch because the RPM's don't shoot up

Could be a weak fuel pump. Try fuel filter. If it has stock factory pump I would change it
