I'd suggest he check the plugs for the AFM and throttle position sensor for corrosion and break out the deox-it if there is.

EDIT (addition): I'm not sure if this is how it works, but what if he unplugged the throttle position sensor. That would isolate it as a test but I'm not sure if/how the car will run without it.
