prob is my car idles at about 2200 rpm, and makes this crazy humming/resonating sound through the air tube. any ideas?
 
That would be your IAC. Idle Air control valve. Only the Ford part or a model which has the internal bellows type diaphragm is a suitable replacement. The aftermarket types which have the long cable lead will not work on the SC, so don't waste your time and $. This is because they have to be mounted 180 degrees out and the oil filler tube prevents that. :)
