Anyone have this idle issue? 90 Xj auto
I know Idle issues are a pretty common thread. My current issue is in my 90 automatic 4x4 Laredo the idle jumps to 1500 rpm when I'm in park or neutral. When in drive it drops down to normal, accept sometime it stays high around 1000rpm. Lately it was hit n miss, but the last couple days it has been pretty constant. The tps was good last time I checked. Wondering if anyone else has had this issue. Thanks in advance.

No argument with starting with ground checking/refreshing. My 90, the plug for the IAC there on the TB plugs down such I think it got some moisture in there. I suspected the IAC because usually shutting down, then restarting cured high idle. For me, just cleaning the plug at the IAC solved it.

In my case, with an identical "sweet" of symptoms, it was just the plug on the IAC not making a good connection. I cleaned the IAT when it first acted up. Was after it came back I figured out it was the contacts. (and yes, I thought it was the floor mat also.

All good advice here. Check those things.
Your TPS is probably taking a dump.
