Jeep - Wrangler :: 2000 - CE Light Came On / Lurching And Hiccuping Of Engine

I have a 2000 Jeep Wrangler, manual transmission, 6-cylinder. I accidentally let the battery die in September. I got a jump, and it was fine until we got a cold snap. (We live in NJ.) On the first cold day (October), the battery was dead again. The battery is about 4 years old. I got it jumped, and it was fine, but the CE light came on. I have been dealing with the CE light and generally lousy engine performance ever since. (The car is lurching and hiccuping.) I have had it to the shop four times since the initial dead battery in September.

I bring it to the shop, they hook it up to the computer, and each time it indicates a sensor problem. They have replaced the 02 sensor, the TPS sensor, cleaned the throttle body, replaced several spark plugs, and swapped out the clockspring. It has been to the shop four times in the past 5 weeks. I even switched mechanics after the first one said he was going to replace the 02 sensor and I looked at my records and pointed out that he had already done that back in June. (At that point, they said "Oh"" and tried replacing the TPS sensor.) The 2nd mechanic also got the TPS sensor code and I told him that the previous mechanic had already replaced that one, as well.

He went to a discussion website for mechanics and discovered a "design flaw" that a majority of mechanics said could be rectified by replacing the clockspring. So he tried that. Every time one of these guys does something, the CE light goes off and they test-drive it and it seems fine. Then I come to pick it up, after hours, hours later, when the car has completely cooled off, and the CE light is back on. Yesterday I picked it up and the CE light was on but at least it was running better. Then I drove it 90 miles and it was hiccuping badly by the end of the trip. Also, I filled up my gas tank at the beginning of the trip, and the tank is now between 1/2 and 3/4 full. Horrible mileage. My husband made the same trip in a different car, also a Jeep, and also filled up at the beginning, and his tank is more than 3/4 full.

I know I can take it to Auto Zone and get the code, but I'm not hopeful that the code will say anything other than what it has already said, i.e. O2 or TPS sensor.

Jeep - Wrangler :: 2006 - Getting Check Engine Light - Electrical Malfunction?

I am having a “Check Engine” light problem on a stock 06, 4 cylinder Jeep Wrangler with manual transmission. A local highly regarded independent mechanic has had it in his shop 3 or 4 times for more than a day each time. On the first visit he replaced a purge solenoid valve and reset the light. It stayed off for more than 400 miles and then relit. He went over it and checked the wires and connections and reset the light. Again it stayed off for some time and then relit. He has checked the Jeep site.

After the last visit he suggested I drive it and see if it would reset itself as it had been doing in the past. It did reset itself twice but it only stayed off for 10 miles the first time and 2 the second. The code indicates an electrical problem and he is now planning to drop the fuel tank and check the wires and sensors there. The next step may be an ECM transplant. This is only an emission system problem and the mechanic says it is OK to drive. We do not have emission inspections here. How important is it to fix the problem?

Jeep - Wrangler :: 2005 - Won't Start - Battery?

I tried starting my 2005 Jeep Wrangler yesterday and there wasn't enough charge to get it started. I got a few slow revolutions and that was it. I gave it a jump and it started fine. Drove it for an hour or so and then went to restart it 3 hours after I shut it off and it was dead again. Another jump and I drove it for an hour (home). I was able to start it a few hours after that on its own, though it struggled to a bit.

Tried again this morning and it was dead from sitting overnight. A few other bits of info:

With the key in the ignition, the charge indicator is hovering just above 9V (it is a 12V battery) before I try to start it. When engine is running after start, it jumps to around 12V.

I am pretty sure I didn't leave the lights on or door open overnight. I haven't noticed the engine struggling to start leading up to the dead battery.
After I jumped it again this morning, it seems to be idling very low. In fact, the engine shutoff when I let it idle in neutral with my foot off the gas for a few seconds.

When I got in the Jeep this morning before trying to start it, it had enough charge for the radio and dashboard. When I turn on the lights/highbeams it struggled and the high beam indicator on the dashboard (blue light) was flashing. Battery is not too old. I don't have the receipt with me, but I think I bought a new one 3-4 years ago. The +/- connections are clean with no corrosion. I didn't look too closely, but I didn't notice any obvious connection issues from the battery leading into other components.

I'll probably go buy another battery, but wanted to check with the experts out there to see if there is anything else I should be checking. If I do get another battery

Jeep - Wrangler :: Cable Connector On Negative Battery Pole Is Partially Melted

Over the past year or so I have noticed that when I press the clutch on my 1985 CJ-7 258 that the headlights would get brighter. This happens when driving or just sitting at an idle. This happens only after you press the clutch enough to take up the usual 1/2-1 inch of play in the clutch pedal. When you release the pedal, the lights dim slightly. Another thing that may be related---over the past few months, it has been a bit sluggish to start until, finally, it wouldn't start at all. I looked at the battery and the cable connector on the negative battery pole is partially melted and ran down onto the top of the battery. What the problem might be? I'd hate to get a new battery and just have the same thing happen again.

Jeep - Wrangler :: 2004 - Rust On Engine Block

I recently purchased a 2004 Jeep wrangler Sahara. In retrospect, I probably should have inspected it more closely. The underside, including the sides of the engine block (below the heads, etc.) have a lot of rust. With little effort I can flake off pieces as thick as a quarter for example. How concerned I should be and what I need to do???

Jeep - Wrangler :: 1997 - Lurching Violently After Engine Warms Up

I have a 97 Wrangler 4 liter that lurches violently. It runs fine until the engine is warmed up. After the engine warms up it it begins lurching. When I put the clutch in, the lurching stops. When I let the clutch out, it is okay for 1-2 seconds (i can get power and advance the vehicle), then I put the clutch in and repeat that process. When I give it a little gas with the clutch in, the engine runs smooth - so it doesn't appear to be a gas problem. When I give it gas with the clutch out it lurches violently.

After pulling it into my garage I let it idle to about 5 minutes. It idles rough and is about to stall, when it apparently shoots a little more gas preventing it from stalling.The check engine light has come on. I took it to my local mechanic who cannot find the problem. The "computer code" indicates a faulty oxygen sensor. He also checked the fuel pressure which is okay.It has 120K miles and otherwise has been a great vehicle. It has been well maintained.

I just replaced my batteries today on my 2011 F250 because of a no start situation.

However after I replaced them and started the truck the check eng lite came on....

Jeep - Wrangler :: 1998 Won't Start / No Noise

I own a 98 jeep wrangler. Love the little jeep. But....big BUT...at random it chooses not to start, not sluggish start, dead absolutely no noise. I have spent well over 1500. dollars on new starters, batteries, ignitions, ignition cylinders you name it I have replaced it. This last time it started every time for well over a month, then one evening it just didn't so I let it set for a couple of hours as usual and then it started and we came home. I love my mechanic he is patient and doesn't make fun of me when I ask dumb questions...but this he can't figure out.

Jeep - Wrangler :: 2001 AC Is Not Blowing Cold Air

I have a 01 Jeep and the AC is not blowing cold air. When I went to get my oil changed they did a check over and said that it is in working order just lacks any freon to get it cold. So I went to get a bottle to do it myself. Doing what it said to do on the bottle I got nothing. The meter says that there is pressure in the system, but no cold air coming out. I noticed that it would engage and then stop after a second, but still will not fully engage or blow cold air.

Jeep - Wrangler :: 1997 - Overheats In Summer

We have a 97 Jeep Wrangler that I have serviced regularly since I purchased new. It only has 97,000 miles since my wife and children drove it locally. During winter, the Jeep drives fine. As the weather warms up and especially when using the air conditioning system, the engine heats up within 10 to 15 minutes of driving. Once, when my daughter was driving in warm Spring weather, the Jeep engine seized up on a highway. We had it towed and the dealership flushed the coolant and it drove OK for a few days. We have noticed that the coolant is burning up in Spring and Summer needing replenishment frequently. We also had the thermostat, water pump, belts, and hoses replaced. The overheating problem (needle moves to red zone) still persists in Spring and Summer. If we switch off the A/C, the vehicle drives OK for about a 1/2 hour but Atlanta summer can be brutal without A/C.

Except for this issue, the vehicle is well maintained and in fact every time I get the oil changed, the mechanics ask if I would sell the vehicle as it is in such great shape.
