Temp creep up at idle = check the health of the viscous clutch on the fan.
And check the Rad. Replacements re cheap and make a world of difference.

OK, so I disconnected the VSS and the problem has disappeared, so clearly an issue with something in that chain. I'll address at a later date.
A larger problem has arisen. When slowing from speed to a full stop, the engine will cut off. If the slowing is deliberate enough and paced enough, it won't stall - but it takes a lot of nursing to happen, and it will cut off in a turn when slowing to take it. It reminds me of a manual transmission when you don't shift to a lower gear to match the speed. Torque converter? Transmission issue?
