Not pulling any codes from my MCU, although it's still driving the mixture control solenoid. Maybe I killed the code-output port but my mileage is around 10-14 mpg with a new O2 sensor so I don't think it's even trying to control the MCS any longer. Would like to replace it. I find lots of MCUs for manual tranny 83's and even for auto tranny 4.0L but none for the 2.3L auto tranny engine.

Anyone have?
