You have a parts Scorpio, what year? How's its engine? Pull it, if necessary install newer heads, store it until needed.

Curious as to how you modeled the steering column bushing; did you remove an original one from your car?

Does that 175 download number mean 175 Scorpio owners are on Thingiverse (hah)?

I always try to cheap out where I can, but for just under $50 shipped for a reman unit on Rock Auto I'd go that route. Especially since your pump seems to be generating a noise rather than leaking. But noises under the hood can be deceiving re their sources. Use your engine stethoscope (I bet you ha...

I'd loosen the belt and rotate the pump pulley manually to see if you feel heavy resistance or bearing rumble. Just replacing the pump strikes me as reasonable. No idea how many miles on yours but my '89 with only ~85K on it when I got it was leaking (one reason the owner decided to let it go-it was...

No idea what the cause is, but try a bottle of LubeGard power steering additive. Company tech recommends it to shush Ford pump whines.

I wonder if a mismatched (P/Ns) IAC is involved in the Sudden High Idle Syndrome. The TSB doesn't mention sudden high idle, but the fly back issue makes sense as causing that.

...But the IAC harness connector is a one-way only plug, it can't be reversed.

Use a crow bar or equivalent to lever it loose, along with Liquid Wrench e.g..

Forgot add above: did you install a new IAC gasket?

EGR is EEC controlled and doesn't actuate at/off idle. Disconnecting the EGR solenoid vaccum hose(s) has no effect under idle/low rpm conditions. What's worth a (desperate...) try is to use a vaccum pump on the EGR nipple to work the diaphragm and pintle, while engine is cold and hot. Not more than ...

Original off-idle stumble on depressing accelerator is likely an EGR issue allowing some extra air into the intake. High idle issue could be carbon deposits on IAC pintle and seat; or an error re soldering the new TPS pig tail to the harness (not sure how, but logic points to that action for diagnos...
