i've got a fitting into the engine about 3" to the left of the idle air control valve. the fitting has two small red vacuum line tits and no electrical connections. the tit for the line that goes to the back of the idle air control valve is broken off. small vacuum hose to ICV has been plugged with a BB. Would this explain poor engine idle when engine is cold? Engine seems to run fine when warmed up. Is this a thermovalve or just a fitting for engine vacuum? does anyone have a part number, can't seem to find it on-line.
