My cherokee is a 1990
When I start it, it idles fine. When its in drive it idles fine. After driving, when I put it into park, it idles kind of high at about 1500. Anyone know why it would be doing this?

TPS/ adjustment, IAC, vacuum leaks, could be a few things.

I had a similar issue, vacuum leaks were the problem.

I think I'll have to look into adjusting the TPS... I had just swapped it out because my old one was bad. I might even work on my vacuum system because it's a little messy. Couldn't hurt
