Mitsubishi Triton: Diagnostics

With respect to the recent report in Ask Smithy of a problem with a Mitsubishi Triton GLXR dual-cab I can say that as ex-Mitsubishi man, there are a few concerns that don't show up with the diagnostic tools. These models are prone to soot build-up and blocked intake manifolds, MAP sensors or EGRs are common, but all usually leave a trouble code. It's more than likely in this case a sticking Suction Control Valve. Turning the car off stops the bind, it loosens and then restarts, accelerates and runs ok. If there were no trouble codes, I'd try the Suction Control Valve.
