    Just wondering what sets the high speed idle on these motors? Is it the temp sensor? It seems it doesn't want to come off high idle now that it's getting colder. I never had that problem last winter. Anyone have any ideas on what to check?

    could be....... if its still sending a "cold" signal to your computer its probably leaving the cold injector on tossing the extra fuel.....

    Hard to get at that valve? Is it common for that to go?

    Can you verify which type you have? Your looking for 2 small (1/4") coolant lines attached to it...

    The older version is electronically controlled VS the newer mechanical type that sits underneath the TB...
