2001 Cherokee Sport
Black 107,xxx miles
stock

just got my cherokee a week ago.




I don't have a lot to start upgrades but would like to in the future. just trying to clean up a few things now and get through the rest of the winter here in pa. the rear bumper end caps need replaced i think. rear drivers side window needs some work. when i drive at night i can see one headlight is brighter than the other even tho they are the same bulb. pictures to come soon.

So i was driving around today and saw the check engine light on. stopped at auto zone and they said that cylinder 3 was/has misfired. one guy there drives a wrangler and said i should replace all the spark plugs and told me where they were located. this is my job tomorrow. if anyone could offer advice that would be great. thanks.

cyl # 3 misfire is common on the 99-04 cherokees and grand cherokees.. the design of the INTAKE manifold is POOR.. here is some info on your POSSIBLE problem...

1803103 - 4.0L ROUGH ENGINE IDLE AFTER RESTART FOLLOWING A HOT SOAK
Date: 09/05/03 (supercedes 1802702 dated 09/06/02)
Model Year(s): 1999-2004

Description: NOTE: This bulletin applies to vehicles equipped with a 4.0L engine. This bulletin involves the installation of a fuel injector insulator sleeve.

Details: Customers may describe a 20 to 30 second rough idle following the restart of a heat soaked engine. This condition may be most noticeable when the engine is restarted following a prior 10 to 20 minute heat soak in hot ambient conditions of approximately 32 C (90F) or higher. This condition may be consistent with short city stop-and-go driving trips and can be aggravated by the use of fuel with a high ethanol content. Depending upon various conditions a MIL may occur due to DTC P0303 - Cylinder #3 Misfire.

This condition may be caused by heat from the exhaust manifold that following engine shut down migrates to the area around injector #3 and causes fuel vapor to form within the injector. This in turn may cause a momentary misfire of cylinder #3 until the fuel vapor is cleared of injector #3. The insulator sleeve lowers the injector #3 temperature to a point below which the fuel will not normally vaporize.

If vehicle exhibits a rough idle, and if a misfire of cylinder #3 is observed following a 10 to 20 minute hot soak, perform the Repair Procedure.

Parts required:
56028371AA Ignition Wire Shield

Repair procedure:
1. Cut insulator sleeve, p/n 56028371AA, to make two (2) insulator sleeves about 25-30 mm (1 in.) in length. See diagram.
2. Install one sleeve around injector #3, with the slit on the upward facing side of the injector. Install the other sleeve with the slit on the downward facing side of the injector.
3. Confirm sleeve is flush to intake manifold surface around injector.
4. Check injector #3 wire and ensure that the injector is rotated to a 2 o'clock position (from driver?s side of vehicle).

ok, so it only took me about 1.5-2 hours to change the spark plugs for my first time.

does anybody know where i can get or what i can use for the wire shield that 00xj-classic is talking about?

there is one sleeve for the injector. there is also a heat sheild that goes on top of the intake manifold.. both can be purchased at your local jeep dealer.. the heat sheild should be installed for free, its a recall.. I have witnessed three cherokees burn from not having that sheild..one 02 g/c and two 2000 xj's. If the jeep has sat for a couple months or years mice get up in the engine and make little homes.. well it seems one of there favortie spots is on the intake manifold.. so as soon as you start your jeep from storing it or just it sitting the heat from the exhaust manifold catches the debris on fire..about 2 months ago my 93 had a simmilar issue but it never caught on fire just smoked.. get those installed asap.. you dont want a engine fire..

The heatshield on top of the intake was indeed a recall fix (a safety recall), don't let them charge you for it.

thank you guys for the info, i just got the recall number and am planning on going to a dealer within a week to talk to them about it.

so, i have a question about my rear drivers side window.... the window molding between the piece of glass that moves and one that doesnt is almost like it is stretched away and doesnt seal correctly. i can hear the wind noise while i'm driving.

window closed


window open


does anybody have input on how to fix it? would i be able to find that molding strip somewhere and replace it? not sure if its that simple or what would have to be done. thanks
