TPS usually causes this. You replaced it so that may be out. How does it run when you start it cold? Does it run well with a higher idle until warm? There is a coolant temp sensor ear the thermostat housing, I see you disconnected it but this is what tells the computer what temp the engine is at ect, this causes similar issues when bad and if bad would not make any difference, this part is relatively cheap. I would also check the pressure regulator.
