What year and engine? Turbo/NA? Such information always helps.
I assume that by ETS you mean Engine Temperature Sensor. If it's something else, then the engine temp sensor is something to look at.
The LH2.2 900 16V had major cold idle issues. Some folks 'fooled' the engine into running better by biasing the temperature sensor to make the engine think it was warmer.
You replaced the AMM. Did you adjust it? (again, the ability to adjust depends on year). A mis-adjusted AMM can give a poor cold idle.
Of course, chasing down vacuum leaks is a big deal. There may even be a leak that closes up once the engine is warm. Nasty thought, but something to look at.
