I just got this 92 prelude. It's all customed out. the only thing is when you start it cold it will idle surge...rpm's droping and rising repedatly until u press the gas or until it warms up. if u drive off before it is finished warming up it will continue to surge until it heats up and will then stop, and runs great after that. I have tried cleaning the EACV, and when i put my finger over the bottom hole leading to the FITV and there is no suction so i asume the FITV is good? i really dont know what to do...i'm not loaded with money but i'd like to find the issue causing the car to idle surge.
