    could be a multitude of things.
    check the iacv, make sure the wax ring inside is screwed down all the way.
    clean out your eacv with some carb cleaner.
    check the intake manifold gaskets.

    when was the last time you did a coolant flush?
    if you think its the HG, do a compression test.
