I think I know what the issue is, I am just fishing for a bit of clarification before I move forward. When I cycle the key ON. I can here the actuator click about 5-6 times. The truck has low power and you can clearly hear the exhaust is restricted. I am assuming that the VGT vanes are corroded and sticking causing the turbo to not work correctly. I think this can be rectified by disassembly and cleaning or turbo replacement. If anyone has an experience with this feel free to point me int he right direction. Thanks!
