Re: idle air control valve problems on a 91 5.0
These are all parameters or tables found in the PCM. They have to be accessed & changed through a custom program (chip). We use the SCT Advantage (Superchips Custom Tuning) at our shop but a shop using Autologic, Diablosport/Chipmaster, or other custom tuning software can make the necessary tuning changes for you.
