When my Mustang warms up, it emits black smoke and the engine starts idling. 12, 18, 26, 42, and 92 were detected. I replaced most of the sensors, but it still doesn't work. Please help.

Code 12: System cannot raise engine speed above normal idle. This means the ECU was unable to raise the idle 1500 RPM during the self test. The IAC could be faulty, disconnected or maxed out.
Code 42 & 92 : system rich.
Code 42 passenger side sensor, as viewed from the driver's seat
Code 92 is the driver side sensor, as viewed from the driver's seat.
The rich condition may be a result of the other codes. I'd probably take a look at code 12 first and then probably focus on 18 and 26
