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.

SOURCE: Very rough idle on 2002 Jeep Grand Cherokee Limited Edition V8

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

If your engine light is on, please get a free scan at your local parts chain and send us the trouble codes. Recommend you start by removing the idle air control valve and cleaning the valve and passages as well as the throttle body with carb cleaner. Check the operation of the valve by hooking up the connector and turning on the key (do not start the car) while it is off the engine to see if it actuates. Please let me know if you have questions.

  1. Remove air duct and air resonator box at throttle body.
  2. Disconnect electrical connector from IAC motor (#4 in picture).
  3. Remove two mounting bolts (screws).
  4. Remove IAC motor from throttle body.
  5. clean valve, passages, and throttle body (#2)

2001 jeep rough idle when started


  • CEL lamp on key on?
  • all fuses good?
  • CEL goes out running (check engine light)?
  • no, then scan it.
  • yes, then get a tuneup, every 60kmiles, minimum.

rough idle means MISFIRE
this can be just a dirty EGR valve
but you never stated what engine is in the bay of the many.

If the "Check Engine" light is on, have someone get the OBDII codes with an OBDII scan tool. If not, check the plugs, distributor, plug wires, timing chain, and compression.

Look for a vacuum leak at the intake manifold. Spray (flammable) brake clean around the area while the engine is running and look for the idle to change. Also check for a vac leak at the brake booster by pinching the Vac supply line and see if the idle changes.
