after looking on google I found that part number corresponds to FORD VALVE VENT AG9N7B344BA. I would therefore check the inlet manifold and air intake for a broken/missing pipe.

I would assume it's the vent for the gearbox and would attach after the airflow is metered. Air getting added after metering could well explain your loss of power.

Sorry probably not much help
