You could possibly have a bad EGR valve which would affect the vacuum which affects the idle. Check for a vacuum leak first then check the egr valve

It is on the driver's side of engine, mounted onto the intake manifold-right in the middle of the manifold, but on the side. It has a removeable metal tube on it coming from the exhaust manifold.

With the egr valve, there may be an attached "egr valve vacuum transducer"-a little device only there to increase or decrease the vacuum signal to egr valve, based on the amount of back-pressure in the exhaust. The transducer valve has a vacuum hose from the engine, a hose from transducer to the egr valve, then another hose from bottom of transducer valve to monitor exhaust backpressure. Do not worry about the transducer valve when servicing the egr valve.

depends. if its the 4.0 6cyl it doesn't have an egr valve. if its the 8 cyl its in the right front of the motor

Soungs like egr valve is stuck open. Take it off and look inside small hole on the bottom. The pintle inside should be all the way closed. If not then replace the egr.

The symptom you describe can be caused by either a bad or dirty EGR vavle or a broken / defective vacuum line.

Try this
1. disconnect and plug off the EGR vacuum supply line

2. Connect a vacuum hose of equal size to the EGR valve.

3. Start vehicle

4. draw a vacuum on the line orally.

a. the engine should die or run really bad.

5. Restart vehicle and repeat checking for same result.

6. If EGR valve is performing correctly as stated in steps 4 and 5 thern you most likely have a bad / cracked / damaged vacuum line somewhere.

7. Reconnect original vacuum line to the EGR Valve

8. Locate source of Vacuum leak.

Check:
- Fresh Air Intake Hose: Clogged or Damaged FreshAir Intake Hose.
- Carburetor: Worn, Faulty or Damaged Carburetor.
- Mass Air Flow Sensor: Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit.
- EGR Valve: EGR Valve Sticking Open/Leaking.
- Idle Air Control Valve: IAC Valve Sticking or Faulty.

Good luck.

IF ITS A 4 OR L6, SOME DON'T HAVE ONE...IF YOU DO IT IS BELOW THE THROTTLE BODY ON THE EXHAUST MANIFOLD.

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.
