I have an '02 wrangler x 4.0l manual with about 175k miles on it.

I have noticed it idles at 500rpm, I believe it should be more like 600 or 650. Is that correct? This is not like old cars I am used to where I can just turn a screw and adjust it. I believe this is electronic.

I'd greatly appreciate any info anyone has on this.

yes its electronic, and you cant adjust it
could be a dirty idle air control unit, I would take the throttle body off give the Idle motor and throttle body a good cleaning, its very easy.
