      The short of it is that on a fuel injected car with air in the system it will ‘fool’ the coolant temp sensor and cause the fluctuating idle.

        Thanks Eric, that’s what I figured, but thought I’d check to be sure.

            If you decide to re-bleed the cooling system, i would also massage the radiator hoses too to see if that will help._x000D_
