Fast Idle Control Valve is correct - only on 89-91 Si - not on 88 - also, not on DOHC ZC - the Fast Idle Control Valve is used to advance the idle when ambient air temperature is below -10C (14F)

Interesting. So the reason it isn't on some engines is because it's not a necessary component? Or it just doesn't get that f*ing cold in Japan...

Nope, not nessicary. The reason things like these exist is to warm up the engine and cat faster, a warm engine runs cleaner.
