Re: air intake question
The importance of the FIA system is a bit of a mystery to me because I haven't yet read a thread where its malfunction causes a problem. Based on information in the diagram, I presume the FIA system functions to raise the idle speed when the engine is cold, which seems somewhat redundant with the IACV. Maybe somebody else here knows more about the FIA system.
