I own a jeep wrangler with a 7.2 hemi engine. Manual transmission. When driving and want to stop on a traffic light. The rpm will stay at 2000 rpm until complete stop and then it goes down to 850 rpm.
View 19 RepliesJeep jk with hemi 7.2l manual ... Symptoms of high rpm when stopping before complete stop. And high room when shifting from one gear to another (usually bit drops between shifts). Recently I noticed that this happens only when shifting above 2500 rpm. So if the shifting happens before the rpm reaching 2500 it will be smooth and normal.
View 2 RepliesSo as I was parking my car and I accidentally stalled it. So anyway I return to the car 20 minutes later to leave and when I start it up I notice the engine is idling at 2000 rpm and is making a loud hissing noise from the drivers side on the engine (I think). When I rev the engine it is slow to come back down to the 2000 rpm idle. When I put the car in gear and drive it, it likes to stay at 2000 rpm.
The car will accelerate without me pushing the gas pedal until it reaches 2000 rpm. Also when I shut the engine off, it sputters and coughs, almost like a backfiring motorcycle but rhythmically slowing down until it finally stops (around 3 seconds or so from when I turn the key off). The check engine light is OFF and the car is still "driveable" (I got it home) and typically idles around 900 rpm I think..
Just discovered that both high beams are not working. Regular lights ok. When switch to high beam both go off. I know some bulbs have two filaments, is this the case for this car? Are the bulbs burnt out or something else is wrong?
This is a 2007 Jeep Wrangler Rubicon Unlimited.
There is a whistling noise that is coming from under the hood of my Jeep. It is more noticeable on cold days. It temporarily disappears when my foot is on the accelerator or after I have been idling at a stop sign for 30 seconds. The noise starts again when I start driving.

View 6 RepliesI 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???
View 5 Replies2 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?
View 2 RepliesThe engine was running rough when it hit 2K RPM only. above and below it is fine. replaced the injectors/O2 sensor and it ran well for a couple of months but it is doing it again. when engine hits 2K rpm it will sputter and run rough. engine light gives me code 171 engine running rich or lean. What else to look at..
View 8 RepliesI 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.
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 own a 2003 Jeep Wrangler and for the past 4 months. I have had a squeal coming from the right side front of the engine when coming off the gas. However when I get below 25mph while slowing to a complete stop the sound goes away in most cases. My mechanic has replace the tension pulley along the the serpentine belt and the sound still persists...
View 5 RepliesI 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...
View 2 RepliesI 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!

View 15 RepliesI 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.
View 2 RepliesI 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.
View 5 RepliesWe 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.
