Amarin suggested my high idle issue after W.O.T. and max boost may be related to the turbo waste gate valve. I pressure tested the valve and found it leak down and closed as soon as pressure was released.
I tested a spare waste gate valve I had and found it held pressure until physically disconnected the air hose from the diaphragm
Does this mean the diaphragm is bad?
Something is telling the Idle Control Valve to stay wide open even after throttle is released to idle.
ECU, TPS and ICV have all been replaced and the wiring harness has been check without fault.
What do you experts thinks about a new waste gate valve?
