I bought a 2003 jeep cherokee in Nov. '06 and I just took it in a few weeks ago to have some minor maintenance done, such as, oil change, transmission filter and fluid change and a new air filter. We just got back from a trip and the day after we returned the OBDii light came on. I've checked the manual and it says that it has something to do with the emissions control. I have kept a very careful eye on it. The manual says that if the light is blinking that it can lead to severe damage to the catalytic converter. My question is whether this is something that I need to be really concerned about or not. I traded in a '97 Ford Aerostar that I drove with the same light on for more than 4 years without a problem. It's manual though did not say anything about possible catalytic damage. Any suggestions on what I should do.
I have a 1999 Jeep Cherokee Sport. I have not had any big problems with it until recently. My Jeep has about 100,000 miles on it. I have had a cylinder 1 miss-fire for about 4 months now. I have taken my Jeep to about 4 different places, and they have all done various things to it. They all have their idea of why my Jeep light is coming on. But like most of you, after the mechanic “fixes” the problem, the light comes on again. I have had my injectors replaced, my o-rings, spark plugs and wire on all cylinders, a engine flush, and the list goes on. I am still getting a cylinder 1 miss-fire. I am sick of paying mechanics to “fix” my problem only to have it happen again 2 hour later. Does anyone have any ideas on why this might be happening? I also notice that when my Jeep is idle it runs a little rough. However, when I push on the gas and goes above 5 mph the roughness subsides. If you have any advices, please post it.
Thanks!

My 01' Jeep Cherokee Limited engine light is also coming on and it take a long crank before starting. It has been getting misfires on multiple cynd.
I had it serviced and they ask for carbon cleaning and new fuel pump - done. A month later the engine light is back on. I took it to a different dealer - since my mechanic can't figure it out. The dealer told me to to do the carbon cleaning and add a fuel pump - not!
Does anyone have any idea what causing this. Temperature sensor? O2 sensor is OK. Help!
I Also too have a 2001 Cherokee with the 4.0L I-6. and I also have had problems with a Misfire, I changed the plugs with no avail, Next I replaced the Fuel Injector on the Cylinder that was misfiring and BINGO fixed the problem No more Misfire, So anyone that is dealing with a Cylinder 6 misfire and have changed plugs try the injector it is Very Easy to fix and Easy to access, JUST REMEMBER to Bleed off the Fuel Pressure At the Pressure Relief Valve at the front of the Fuel rail before removing Injector or you will be covered in gas!! HOPE THIS helps all you fellow Cherokee Owners!!
I have a 2001 Jeep Cherokee Sport, and like many others have had multi cylinder misfires. The mechanic at my dealership said the coil pack was burned out because of all the misfires. This is the second time its been replaced. Has any one had this happen to them?
Of course I know of no way of knowing if the coil pack even needed to be replaced. And now the mechanic is suggesting I have the engine De carbonized. You would have thought that would have been the first thing he would have done before replacing two coil packs.
I bought a 2004 Grand Cherokee Sports V6. At 48k the engine light came on for a day, and then went off the next day. What is the cause?
I own a 2001 Jeep Cherokee 6 cyl and had check engine light turn on. I was told it had 4 errors. cyl #1 misfired twice, cyl #4 once and emission issue. I replaced the fuel cap and gave 'er a tune up and started to use use a cleaner high octane (91 or 92) fuel.
These motors are thirsty and the Daimler/Chrysler motors run strong with high octane fuel. It is costly, but then I get 195 horse power with torque enough to pull and launch my boat.
Hope this helps.

I also own a 2001 Jeep Cherokee. It has close to 100,000 miles. The advice to hold in the trip reset button, turn the key to the run position, then release the reset button is very good. When my check engine light comes on (once or twice a year) I do this routine to see if there are any error codes. But doing this doesn't clear the check engine light. So, after checking to make sure there are no codes, I simply remove the battery (positive) cable, count to 10 and reconnect it. Check engine light is gone! If there are error codes, I write them down and take it to the dealer. I love my Jeep!
To the person with the 2001 jeep with 100k miles, where did you find what the codes meant? I have had the check engine light on for 20k miles and I can't seem to get it fixed. I have changed the plugs, new gas cap, O2 sensors with no success.
I have a 2001 Jeep Cherokee Sport. My check engine light is on again. The dealer told me it's the gas cap when filling up. The Jeep is running fine. So all I did was disconnect the battery, wait 20 minutes and put it back on. Now the check engine light is off and has not gone on for a while. That did the trick. Hope this helps.
I also have a 2001 Cherokee Sport. I had the same problems with the check engine light and the rough idling, and lost a little mileage. After doing all the things mentioned in this thread, I was told by a very knowledgeable gentleman at the auto parts store to check the fuel injectors, because the plastic housing around the injectors are known to develop little cracks. If you aren't able to see all the way behind them, run your finger around the back and feel. Lo and behold, one was cracked. Replaced it and there have been no more problems with misfire codes... only the annoying one that regularly happens with the gas cap.
I have just bought an immaculate 2001 Cherokee Sport. This is my first Jeep and I could not be more pleased with it. I looked at a few before purchasing this particular one, and they all (except mine) seemed to have a similar problem. The front and rear passanger windows did not work from the door switches... only from the master switch. Any other problems like this out there? Any suggestions in case it happens to mine?
Thanks.

Like most people on this blog, I have recently purchased a 2001 Cherokee which has displayed the infamous "check engine" light after about 14,000 miles. I brought the Jeep to a local Chrysler dealership thinking that the warranty I purchased would cover any engine related issues. (Otherwise, I would have never have brought it there) The mechanic just called me to say it needs about 2,400 dollars worth of work, (cat converter, vacuum tubes, rear breaks, etc.) none of which is covered by the warranty I bought. Needless to say, I told him to go ahead with 0% of his recommendations. They will however be sticking me with a $92.50 diagnostics fee.
PS I have also had the window power problems. Just give the driver's side switch box a light tap with your fist and look for the green light to turn on in the window switches on the other doors. It's as simple as that, but you have to do it often.
