Sorry I forgot it's the base model, non turbo 2003, it seems it goes to a vacuum pump, in a real awkward place below the breaker booster, I'm hoping it's not the pump. I did an engine swap, on a car that was not running.
I also came across a relay,/fuse yellow and orange in color, 3, pins that fell off and I cannot find where that plugs into, wondering if that had something to do with it

Pictures would help a lot.

No good without pictures.
And it is a Throttle Position Sensor, there is no such thing as an idle position sensor.
