Engine runs on

[canuck]

TD42's are shut down by the fuel cut solenoid on the injector pump so I suspect you fault will be related to that. The solenoids are known to fail though usually they will fail in the shut down position and not allow the car to start.

Most likely a weeping injector or 2 or 3 or 4....

I've had that on my rig. The solution was a 4x normal dose of injector cleaner. Not sure if it was a gummed up fuel cut off valve or a gummed up injector. But that fuel system snake oil seemed to have taken care of the problem.
