Idle Issues

My 92 bronco won’t idle correctly, it idles too high. I replaced the o2 sensor and it only made it idle higher. Any ideas / opinions as to why

IAC might be stuck. Or else you have a vacuum leak.

Idle issues

I’ve pulled of the IAC cleaned it, was planning on replacing it anyhow. I’m leaning toward the vacuum leak. When you stomp on the gas when it’s in park, the idle will drop by about a grand and then clime back up. Would that be my choke, and what vacuum lined does affects the choke.

You don't have a choke

Any idea what vacuum line I’m looking for? And is there a vacuum line diagram in the Haynes book?

There is supposed to be a vacuum routing diagram on the radiator support or attached to the under side of the hood.
