I'm hoping you can help me figure out what is going on in my Jeep. A bit of history...Bought Jeep in 2003 and paid off in 2006. The only problems were high mileage (95,000 at purchase), a corroded battery terminal (replaced), and the (I suspect) Throttle Control Positioner is weak. Have taken very good care of care (oil changes, tune-ups, tires, etc) and it has neber really let me down.
Until now.
Something is causing a power drain and sucking brand new batteries dry in as little as 1 day or as slow as 2 weeks. I removed or disconeccted items such as my radio, power outlets, etc. I've checked every fuse incase something had blocked a fuse slot open. The alternator is fine and I cannot find any lose wiring or poor contacts.
Any ideas? Is it possible for the solenoid to "hang" and cause the drain? How would i test it? Could it be something in the throttle control positioner since i keep putting of repairing it?
Any ideas would be most appreciated. I have been diagnosed with severe COPD and my Dr. does not want me to work so i cannot afford a mechanic and i cannot afford a new car either 9this one is paid off, looks decent, and it's been good to me).
Thanks to all of you.
When I start it it runs great cold. It only starts to run "lumpy" after it has fully warmed up and is running at low speeds. So,, at every stoplight, it wants to stall, almost does, and then when I come to a complete stop it recovers just-in-time (at about 200rpm where it is really shuddering ).
It is not the trans, because it does it in neutral, with or w/o the O/D on. There is a check engine light that comes and goes.
I have a fixed income and three kids. Can anyone save me some $$$ and give me some good advice on this?
Thanks so much!

It started having issues starting, especially when it was cold. When it did run, it would often have trouble accelerating. Eventually it would just refuse to start for weeks on end, and then randomly start up again. Finally, after a month or so of not starting at all, I tried banging on the gas tank while my buddy cranked her, and she started. The mechanic I took it to confirmed that it was probably the fuel pump, but being that I didn't want to pay $500 for the job, I decided to do it myself.
I dropped the tank, replaced the pump (correctly, to the best of my knowledge), and tried to start it again... Still wouldn't start. I checked the sparks, they were good; then checked the fuel pressure... none. So based on this information, the issue seems to be within the fuel system. I then replaced the fuel filter and the pump relay... Still nothing. So I started paying specific attention to the sound of the pump itself when I turn the car ON (not starting). From what I understand, it's supposed to make a sound for a few seconds, then stop. Mine only makes that sound for maybe half a second. And here's the funny thing. After like the second or third time I turn my car on and off, the pump stopped making the sound altogether...
I thought maybe the auto shop gave me a faulty pump, so I exchanged it for a new one. After a reinstallation, the jeep STILL won't start... And the fuel pump makes the noise only every so often when I turn the key to ON, maybe less than half the time...
So I'm thinking it may have something to do with the electrical system going to the pump itself... perhaps it's getting current but not enough? Anyway, I am absolutely stumped here... Can anybody help?
Sorry for the long post, but thanks in advance
My truck was stalling at stoplights, and replacing the oxygen sensors fixed the problem. However, I was having no problems with it starting. How many miles does it have? Have you replaced the plugs? What other repairs have you had? Many times when you have symptoms like this it is the ECU (Engine computer), not a mechanical problem. I replaced my computer at 98k, and all of a sudden everything worked great again. :=)
The computer was $200.00 on Ebay motors. It will cost you $1200 at the dealer. FYI
Sorry, but you have to be just a little more specific due to the plethora of problems these trucks can have.

The symptoms you are describing have more than one solution. There could b e a jammed pinion on the AIC valve, you could have a blockage in the air intake and a filthy air filter. SO, 1st-get your code (if any) checked out. If it is an o/2 sensor have it replaced, If it is still acting up then you need to concentrate on the MAF and AIC as culprits. Good luck! -Chris :confuse:
It is going to cost you $250 for the new sensors, then a separate fee for someone to install them for you. I would ask a friend who may be a good mechanic and then just slide him 200 bucks to put them in,
If it needs to be replaced, go to www.autocomputerexchange.net. They have every computer there is, and I already checked it for you. $199 gets u a new one, and after you supply them with your vin# and mileage, it gets all the software and updates from Jeep before you even get it, and just plugs in. It is either in the engine bay, or under the passenger side of the cabin. If your Jeep is running poorly, take it to the nearest shop and get the codes from the ECU, then they can tell you if the problem is computer, sensor, or hardware issue. Good luck. :sick:
Good luck!
Mechanics and I don't know. Mechanic wants to change the timing gears.
Any thoughts?
Also the mileage according to the display is all over the place but not where it should be. The guys at the shop have been good with all of this and are not charging me for the extra time involved.
We've had all of the fuel system cleaned, new fuel pump, coil, plugs, tuned, etc. No one seems to be able to figure it out. My daughter drives this and has learned to live with it but I'm going to trade unless it can be fixed. Scares me.
Any help is appreciated.
I can guarantee you it is an O/2 sensor. Is the check engine light on? If so, go get it checked out. Many places will check the code at no charge, hoping to earn your business.
My 99 V8 Grand Cher with 133k started doing the same thing. My engine has 4 0/2 sensors, and it cost $600 (total w/ parts and labor) to have them all put in.
Totally fixed the issue.
Good luck. I sold my Grand Cher, and bought a Kia Optima EX, so this will be my last post here. Hasta La Vista Baby!!!
