No I have not, I just pulled a vapor canister off of a 98 V6 4 runner, thought I might swap it and see if it goes away. I would be curious if the valve closes and opens under certain conditions or if we have an electrical issue. I will keep you posted once I figure it out.
Did you remove the idle air control valve to clean & test it? Would also need a new rubber O-ring type gasket to re-install it. A dirty/malfunctioning/leaking idle air control valve will cause high idle. If ya addressed this & it still had a high idle, did ya ever figure it out? Curious to know.
