Jeep - Wrangler :: 1999 - High Idle RPM And Hissing Noise
Aug 22, 2014
So 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..

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.

Jeep 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.

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.

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?

My 2004 Rubicon has been having some idling issues. It idles kind of rough (+- 200 RPM) and is hard to start. I tried to start it recently and after 4 cranks, it started then the CEL came on, and has been on ever since. I have recently moved from Washington state to Houston Texas, and the problem starterd here in Texas. I checked the code and am getting a P0505 code. I had a mechanic replace the IAC valve, Checked for vacuum leaks, and cleaned the throttle body. The mechanic says the output from the main computer appears to have burned out, and needs to replace the main computer(for $1000). The mechanic can clear the CEL, but after turning the jeep off then back on it reappears. The mechanic says he verified the computer was the problem by installing a known good computer and it cleared the problem. Does this sound right to you? If my computer is bad, wouldn't my whole operation be affected?

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.

Video of Noise: [URL] .....
I am getting the above noise on startup, it goes away after 5ish minutes. It isn't exactly cold out. So I don't think its the oil viscosity. Its not a bad oil filter flow back valve, and its way longer than the oil lifters should make noises. I don't think it is a cracked manifold, I think the noise would be different.

I get a noise from behind the radio of my Jeep wrangler 2003 that sounds like a vibrating spring that is hitting metal. I get it in the lower "harmonics" you get as you just shift into a lower gear. It doesn't last long and goes away as you rev up in the gear.

I've got a 2004 Jeep Wrangler SE 5-speed with 83,000 miles on the 2.4l PowerTech engine in it, and it's making a very strange noise that I can't pinpoint.
So first, the noise itself. It sounds like a metallic tapping or ratcheting, like the sound of raising of a large chain hoist. Fairly high-pitched, audible inside and out. Not incredibly loud (I have to point it out to passengers) but loud enough to bother the hell out of me. The closest I can come with location is "somewhere under the hood."
However, the noise is only present under certain conditions:1. The transmission must be in gear. Forward or reverse doesn't matter. Revving engine at idle does not produce the noise.2. The transmission must be under load, i.e. when accelerating or releasing the clutch in 1st to begin driving. Letting off the gas stops the noise.3. The noise only exists somewhere between 1k and 2.5k rpms. Application of throttle at any road speed in any gear with the engine in that RPM range produces the noise. 4. The frequency of the tapping increases with engine speed. 5. Ambient temperature appears to have no effect, but as engine temperature increases the noise tends to disappear. Not always, though, as it shows up sometimes when the engine is completely up to operating temperature. 6. I don't notice any kind of performance issues related to the noise. Power's normal (for a 2.4l Chrysler 4-banger, that is) and gas mileage is within the EPA estimates.
Things I've investigated:1. I'm pretty sure it's not lifter noise. A bottle of Seafoam made it run better, but the noise persists. 2. I've checked the catalytic converter heat shield. It's on tight. I found the flange where the exhaust manifold meets the downpipe was a bit loose, but tightening it down didn't eliminate the noise. Getting underneath and shaking the hell out of every component of the exhaust system I can reach produces no results.3. Engine mounts show normal wear. Transmission mount appears fine. 4. No check engine light, and all gauges read normal. Hooked up a code reader for fun and it came back with nothing.
As the noise only shows up while driving, I can't just crawl under there and poke around. The best I can do while driving is feel for related vibration, which gives me nothing. Whatever causing it, it's not transferring up through the stick.
In the may-or-may-not-be-related category, I've got a bit of oil consumption and a clunky transmission, but according to the various Jeep forums I've found, those seem to be fairly normal.
We got some snow the other day, and as I cleared it off I allowed the car to warm up for about 20 minutes. When I got in and drove it, the noise was greatly reduced. Not gone, but barely perceptible.
I spent a couple hours on YouTube the other day, trying to compare my noise to videos of other Jeeps with drivetrain issues, and found nothing even close to similar. Whatever's making this noise, it's not common.

2004 Jeep Wrangler Sport 5-speed Bought used 2yrs ago. 76,000 miles Only seems to happen after driving for more than an hour. When I either back into my driveway or turn sharp into a parking sport, mostly to right, I get a bumping sound, like something rubbing. My mechanic has replaced the sway bar links, front rotors, axle yoke, had a front differential leak so seal was replaced, and am still getting the sound. Tires Bf Goodrich All Terrain Do not do off road.

I have a '98 Jeep Wrangler with various problems, but the most recent one has to do with the turn signals. When I intentionally use them, they seem to be working, but when I haven't signaled I still hear the ticking sound, only double-time. The sound is normal when I turn the signal on, and only stops when I apply the brake. I recently took the top off and left the Jeep uncovered in a couple of storms. Could this have caused electrical damage? Also, the left turn signal has required some finesse for as long as I've had the car--I've always needed to fiddle with it to get it to turn on--so I'm wondering if it's a wire connection that has deteriorated over time.

I have a 5 speed 99 Jeep Wrangler and when the car is running, it's extremely hard to put the car into first gear from a standstill. However, once it's in gear, shifting is fairly normal but still offers a little resistance. I feel like I have to wiggle it into gear. When putting the car in reverse from a standstill, the gears grind terribly.
Once the car is off, shifting is still difficult until I put it in reverse. Somehow, this "fixes" the problem and everything shifts smooth as a dream until I start the engine and then it's a 50/50 shot until it eventually fails later on.

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!

Vehicle will not exceed 20mph. Vacuum leak can be heard coming from around the intake area on the driver side. Cannot detect where it is coming from. All vacuum hoses seem to be connected.

My Jeep does not always start. All the dash lights come on, but when I turn the key to start the engine, they all go off. The lights stay off, and the engine will not start. The ignition won't even click... it's similar to a dead battery. When I turn the key back to its original position (when first inserting), all the gauges spike and the needles jump really high for a split second. When the door is open the gauges keep jumping (spiking). After waiting for 30 minutes, the engine will start fine like nothing was wrong (except the fluctuation in idle). It would rev high at idle sometimes, and sometimes it would idle low... so low in fact the jeep stalls. I have read about the symptoms of crank/camshaft sensors and relay, but I wanted to make sure from people that know more than I or have faced this particular problem.

Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.
I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..
I have a Takeda intake installed and I re-tighten the fittings.

2004 Grand Cherokee. I was pulling a heavy trailer 1000 miles, and while coming down a mountain pass 50 miles from the end of the trip the check engine light came on. All other gauges (oil pressure, temperature, etc.) had not changed while climbing or descending and I was in low gear while descending to save the brakes. I drove the rest of the way to the destination without incident. I tried turning the Jeep off and restarting it several times to see if the check engine light would turn off and it stayed on. The next morning the light was off when I restarted it and has not come on again since. I hooked it up to a scan tool and received 2 codes: P0152 and P0132. 2 days later I noticed that it was revving high while idling and in Park. It would rev between 1500 and 2200 RPM while in Park, and at 900 RPM while in Drive. Also, while travelling at freeway speeds it seems like it's trying to downshift for no apparent reason. I hold the throttle still and have even tried cruise control and it intermittently increases engine speed, without changing ground speed. I assumed that I got the transmission too hot while climbing/descending and that the error codes listed above (related to O2 sensors) were associated with that, but now I'm wondering if something more has happened.

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.
