My 98 Jeep Grand Cherokee had the same problem. Over heated when standing still. Took it to dealer and they could not find any problem with cooling fan. After doing my own investigation I found out that the electric cooling fan would begin to seize up after about 1hr. of operating. (gets hot)

The dealer would look at fan and see that it was running and think its ok. The problem is, it wasn't running fast enough.

I have a relay on the right side of front fender and jumped the fan to stay on with motor off. (must know what your doing). After about 1hr. fan started slowing way down. Returned it to dealer told them what the problem was. They were not smart enough to jump the relay so they put a couple hundred miles on it even though i told them it works OK when moving. Make sure you tell dealer to use the relay to jump.
Replace cooling fan motor. Works great

The governor pressure sensor is the most likley cause however an inspection of fluid or debris in trans pan would be a good idea to make sure there's nothing excessive in it. Attached is a list of possible causes however the senor would be the most common.

In this day & age I don't see why your asking

You have Evap System Codes obviously

Emission lights as you say

This technology has been here since 1981,
so check for codes & diagnose that system

Google any codes you got, if you want to learn

Check engine light, vapor canister, have any idea

I would start with the gas cap replacement and see if the issue resolves itself. If you do have a problem with the EVAP (canister) system, it may require tools the average person does not have to help diagnose and correct/repair.

Have 2002 Jeep Grand Cherokee, Laredo, 2WD, 4.0 engine. Freon leaking out, can't see visual oil leak, but evap condensate water feels oily. Leak must be evap. How/Where do I find a good step by step...

This job requries special training and tools, have a shop do it and avoid personal injury.

Odds of an evaporator are extremely slim. Get a shop to leak test, Usually seals, nor major components.
