GMC Savana Body Problem

We have replaced with new OEM parts- thethrottle body which includes the idle air control valve and the tp sensor on this 3500 series truck/van and now the engine runs away (fast idle).

Before replacing these parts the engine idle too low.

What could be doing this?

Thank you
