Jeep - Wrangler :: 1997 - Lurching Violently After Engine Warms Up
Dec 21, 2013
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 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.

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.

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???

2 days after replacing a weak battery during a cold snap the engine light came on. 2 days prior to replacement the gas cap warning and engine light came on, but immediately after the installation both warnings went off. Only the engine light came back on 2 days later. I have driven the Jeep 3 times since for about 20 miles total. Total mileage, 18,200. What the cause may be and how to proceed?

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?

2003 Jeep Wrangler LOUD squeal when coming off the accelerator. I've had changed the Tension Pulley, The Belt, Checked the Power Steering, Removed the belt from the AC unit..smaller belt now....Tested the Alternator, it's working like a champ. I have a 4.0L 6 Cylinder. My mechanic wants to check the intake gasket and another intake which he spoke of and I can't remember at the moment however with no guarantees these or one of the two could be the problem. He expects it to be a 5 hour job. The sound seems to be generated from the lower backside of the engine...

Recently replaced crank p.S. that a dodgy mechanic installed app 5 myths ago seems he used after market Chinese shit instead of ome gear well one thing leads to another as all jeepers know with highway speed engine missing when engine warms up l found that instead of running power cable from sensor above the trans fluid tube , in his wisdom ran under said tube causing a short to the computer not realy the best for them , now l have issues with idle ,02 , tps, possible computer.

I have a 76 Jeep CJ 7 with a 258, straight six with a 2 barrel carb. If the jeep sits for a long time, it takes a while to warm up and it lurches as i go down the road as if the gas is not flowing completely or the fuel pump is not working properly. Once warmed up, it runs fine. However, the lurching is becoming more frequent and seems to become more consistent at higher speeds. It seems like a gas flow issue, although i have not done any diagnostics to check other issues.

I have a 2006 4 cylinder JEEP Wrangler. Right around 50 mph the whole car starts to shake pretty violently. I have to slow down back to 40 to get it back to normal. I can seem to get past this most of the time by waiting to shift into fifth gear until after 50 mph but not always!

I have a 1999 Jeep Cherokee Sport, 4.0L (6 cylinder) that has 128,000 miles on it. Within the last two months it has started lurching 1 to 3 times per week. It only lurches once but always when the engine is hot and when accelerating. The engine light does not come on. It also loses power for several seconds at other times. Lastly, it has stalled two times in three weeks when I am coming to a stop. The spark plugs and air filter were changed last week. The injectors were also cleaned.
I do not have the skills to fix it and am taking it to the dealership which is very expensive - thus the money drain. Any thoughts on what might be going on? Or is it better to just cut my losses and look for another car. I would really like to keep this car for another year because I am in graduate school but am not willing to continue with the money drain.

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.
