Hi there, I seem to be having same problem. Replaced thermostat and I can sit idle fine for as long as I want. After a few minutes driving it jumps up to max temp. As it stands I'm idling and have Heater on max and no hot air is coming through. But when it jumps to red when driving I get hot air through fans.

In addition the hose to the right of the engine (when looking face on) is really hot but only after driving, idling its not hot. And the one on the left is normal then a little warm after driving.

Engine fans only kick in when jumps up to red line.

Going garage in morning to rule out head gasket but could it just be PCM recalibration?
