my 96 bravada is a dog when i first start it up, it does it every time i start it up, and last for a minute or so, and it also sputters when i have it at wot, i just changed the plugs, wires, cap, and rotor, it has a new fuel pump and no codes are being thrown, could it be a tps sensor

 

Whats the rpm when you start it up cold.

 

normal idle
