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

vacuum leak, re check your work to be sure the throttle body is properly mounted.
