Why are AC lines running to fuel throttle body?

Never seen this on other cars. Is this common?

I've seen many of them that come from Japan. But according to the gulf specs I don't see them too although the weather reaches more than 50 degree (122 F).

I have an 87' 560SEL parts car that the engine runs fine that I can take parts off to try on this car.
Why would it idel fine in drive & high in park????

what would cause that?
