Ok here goes. My jeep has 61,000 mi on it and I've owned it for about a month. About ten minutes into driving(repeatable... every time) my Jeep stalls out if I give it any gas. If I let it sit for 5 minutes, I can drive it another 20 feet before it dies again. If I let it cool down completely I can drive it for another ten minutes. I got a check engine light so I hooked it up to a reader. I got code P0171 - System Too Lean (Bank 1). I cheacked the exhaust too see if it was red hot from perhaps a cat clog, and have already changed the map sensor. So after throwing 100 bucks down the toilet I've decided to cry out for some guidance. Any takers?

I'm having the same problem. It is currently at the dealer for the third time. At first they replaced the u joints. The second time, the steering damper. Now engineering is saying to put on an " aftermarket steering damper" Not acceptable to me on a new Jeep. Some of the off road guys mentioned tie rod ends, bushings & last but not least the steering box itself. I will let you know what the "pros" come up with & if it solves the problem

Go to post 1028 and follow the thread from there if that sounds familiar.

Please go to the main Jeep Wrangler message board. "Death wobble" can rise from any of the components of the steering system (including the tires). If you get under the Jeep and look for any looseness while your buddy moves the steering wheel left and right, you have a potential cause.

Ok, update time. I tried the O2 sensor and that wasn't it. Here's what else I'm now noticing. When I first start it up(cold) I can hear the fuel pump kick on. But right after it stalls about ten minutes into driving, when I turn the key I don't hear the pump. Not even laying right under the tank. I just hear it bubble a little. Once I let it sit for about 20 minutes, when I turn the key, I can hear the pump like normal again.
So I know the the fuel system is a pressure system, and if it drops below a certain pressure, the pump shuts down. But what if it goes above a certain pressure? Like a half clogged fuel filter? Is the fuel filter inside the tank? Just a thought that I figured I'd throw out there before I go dropping my tank... Thanks for all the help.

Ok, another update, and this one narrows it down I think. I drove until my Jeep started to stumble again (about 10 minutes). Without letting it die completely, I just got out and hit the bottom of my tank a few good times with a rubber hammer. Then I got back in and it ran fine for another 30 minutes... just like that. It did it again, and I repeated hitting the gas tank, and it ran fine again all the way home. Does this mean that my fuel pump is going bad? or is it something else? Thanks.

Just a thought but on my old Mercury Mystique there was a "sock" in the fuel tank on the end of the fuel delivery tube to the internal fuel pump. I never had a problem with it but other owners reported that the sock could get clogged and cause intermittent problems.
It sounds like you are breaking loose some debris in the tank when you hit it with a hammer and then it eventually settles back down and clogs the fuel line.
Now that I think about it, I had an old '72 Impala many years ago that would run for a while and then stop. I replaced the inline fuel filter but it still acted up. The repair shop eventually pulled the tank and boiled it out because they discovered leaves and other things clogging the sock in the tank.

Ok, I dropped the tank and opened her up, and she was as clean as new. I have a lift in my garage so I've been able to inspect everything, and as far as I can tell, there are no leaks and no kinks anywhere in the system. I don't smell any gas in the engine campartment either, so I don't think that my injectors are leaking. Since banging on the bottom of the tank fixes it temporarily I can only conclude that my pump is going bad and a quick jolt is kicking it back on. But I'm not really a fuel system expert, so.... any other suggestions?

This same thing happened to my 97 Jeep Wrangler about 5 years ago. I did not have anywhere to work on it at the time so I sent it to a shop. I had the Fuel Pump and filter replaced and it worked fine (another 60K miles) until last week. It just started doing it again. I am not sure which one caused it- I wish I was because I am going to do it myself this time and I would rather just have to buy and replace a filter than both.
#1058 of 1888 Rear end noise 2000 Wrangler Sport
Oct 13, 2007 (4:59 pm)
Hi, new to this forum. I have a 2000 Wrangler Sport. It is a great vehicle and is lots of fun. However it has been making a growling noise from the rear end when I turn a corner. It only does this after driving for a while on the highway. It does have the factory limited slip rear end. Has anybody run across this problem!
