89' Cherokee Laredo throttle
 

I have been experiencing an odd problem at complete random time right after
start up. As soon as the engines lights up the rpms hit about 2500 to 3000
while still in park with my foot off the gas. I have heard that the
throttle body may be gunked up. Can anyone possibly agree with this, and
would it be difficult at all to pull it out and clean it up?

The throttle position sensor in the 4.0L is subject to a recall:

Good place to start if yours hasn't been replaced yet.

Re: 89' Cherokee Laredo throttle
 

Might try cleaning the Throttle Position Sensor, and Idle Step
Motor by pass that varies the speeds. Both are located on the throttle
body: http://members.cox.net/wilsond/tb/tb.html
