A/C Loping Idle Dies

1989 Bronco 302 Auto

My engine dies when A/C on and I let off the throttle. Also idle “hunts” sometimes (goes from 600-100) up and down while cold.

I know theres a sensor to kick up the idle when the A/C is on. What’s it called, and where is it, and will changing it require depressurizing the system?

Thanks, Chris

You need to clean your idle air control (iac) valve. Easy to do. Search the site for iac and that should do it.
Hope this helps.
Matt
