Little hesitation when load on a '93 Sunbird GT

[billabong22]

Hello! i'm new and i have a little problem with my j-body.

The engine makes a little "lag" when i accelerate. When i shift to the second speed, my car makes hesitations(at 2300-2600 RPM). I already change 1 coil pack, wires, sparkplugs but it still doin...Oh also, i changed the TPS coze when i disconnect it, the hesitations stops(but it can running without tps lol). It always did... Someone?

Thx
