In the process of building out my car (1997) using an AEM Infinity and am looking at idle control options. I know that from the factory the car has multiple valves and solenoids that help control the idle. My question is what I should plan on keeping if anything? I want a car which is very drivable and behaves as normal on the road. I assume that they work in conjunction to help control idle, is one doing the heavy lifting? I do not have A/C anymore.

It seems to me:
IACV-AAC (main idle control)
IACV-FICD (kicks in with A/C)
IACV-Air Regulator (cold start)

Thanks!

Might have problems if you want to turn, I guess. Just delete that too.

Why not do a drive by wire tb and pedal?

What confuses me is why you would think you can remove any of them when what you want is factory idle control which means using all of the factory idle parts

Why would I not?

I no longer have A/C, so if one of the valves really does control for just that then there is one gone. If the other is primarily for cold start and I am able to tune in more correction from the other valve and play with fueling to help correct for that missing then there goes another.

There are plenty of cars that drive and behave very close to oem which have had tons of factory stuff removed. Hell even the AEM manual only discusses controlling idle through a single valve.

Interesting, never even considered it as an option. I assume GM pedal and TB, similar to an LS swap?

You can use basically any pedal... 350z, frs, audi, vw etc.tons of throttle bodies to choose from both oem and aftermarket. If looking at oem the bosch are nice too
