1995 f150 5.0 high idle - low idle - stalling Hello and thanks in advance for any help, we can't afford to put this in a shop right now I am trying to fix myself.

1995 f150 5.0 at very high idle, it will go 30 mph without stepping the gas, and will sometimes not want to shift. At low idle will sometimes stall at a stop. In park it will go back and fourth and the check engine light will go on and off.
Replaced IAC no change.
Replaced plugs, wires cap and rotor no change.
Bought code reader from amazon,
get codes 121, 10, 122, 172, 332.

Any advice on what to try next?

Have you thought about the tps? My truck was experiencing some of the symptoms yours had. That's what it was.
