Jeep - Grandcherokee :: Engine Occasionally Run Rough At Idle / Low Rpm Before Stalling
I've got a 1998 Jeep Grand Cherokee, 6 cyl. engine, ~145k miles. A few weeks ago, I noticed the engine would occasionally run rough at idle, dropping down to a low rpm (~500 rpm, but erratic) for a few seconds before stalling. This usually happens when in park or stopped at a stoplight, but it's occasionally happened at low speed while coasting to a stop (never while accelerating, or while traveling above 20 mph or so). Generally, the car will restart right away, though sometimes I have wait a few seconds to a minute (I was a real popular guy at that intersection).
At first, no codes came up, so I changed the plugs and wires (I was due anyway). That didn't work. (The plugs, while worn, looked normal to me-no residue). I've since had a P0351 code pop up. Before I throw parts at this code (ignition coil, I believe), is there anything else I should be looking into?
Jeep - Grandcherokee :: 1995 / 4.0L - Intermediate Stalling / Shutting Down
What is going on with my car! Anyways I am been having a reoccurring problem with my car that i cant seem to fix. I actually took it to a shop (MIDAS) and the mechanic left the car on for 20 minutes and even drove it around and said it ran fine, but of course on my way home it shuts off. But anyway car starts up fine but after being driven for15-20 minutes the car will shut off, usually at low to idle speeds (stop signs, etc). If i drive the car to work in the morning and leave at night i experience no problems.
Yet if i go to the gym and leave within a hour, i always expect the car to shut off on me so i assume something is being overheated? As far as when the car stalls, i am able to crank the car with no start, sometimes the car starts and turns off right away, sometimes it runs for a bit, and sometimes it wont start at all, only cranks. After 30 minutes the car will work again. When the car begins to shut down and stall, i've noticed if i apply gas i can keep the car half alive as if its trying to continue to work.
Jeep - Grandcherokee :: Idle When Cold / Engine Missing When Warms Up
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.

Jeep - Grandcherokee :: Oil Pressure Goes Low After Driving For About 30 Minutes When At Idle / Low Speed
2001 Jeep Grand Cherokee Laredo, replaced the oil pump with a new one and washed oil pan and replace the pump screen. After driving for about 30 minutes when at an idle/low speed the oils pressure goes low enough to set the check engine light on. The motor sound good sometime there is a little clacker, oil sending unit replaced and have installed a mechanical gauge... What else will cause this?

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.
View 5 RepliesJeep - Grandcherokee :: High Idle Speed And Trying To Shift While At Highway Speeds
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.
View 1 RepliesJeep - Grandcherokee :: 1996 Won't Stay Running / Codes About Idle Control And O2 Sensors
I own a 1996 Jeep Grand Cherokee Laredo V8, and there has been an ongoing problem with it stalling. The check engine light is on and it reads codes about idle control sensor and 02 sensor. I spent a lot of money having both replaced, along with an processor. I had to bring my Jeep to a dealership so they could "marry" the processor to the car. The check engine light went out for about a day, then once the computer reset, light went back on. The codes still read bad O2 and idle sensor despite them being replaced.
The problem is when the car starts cold I have to keep my foot on the gas for a couple minutes or it will stall out. Once it has warmed up the car runs good. I turned the idle pin on the front of the throttle body to try to keep from having to put my foot on the gas but it still stalls. It seems like it is working better in the cold weather. My mechanic says that I may have turned the idle too far trying to fix it and that is why it is stalling.
I just want my car to run without having to warm it up every time. It wastes time and a lot of gas. Could it be something other then what I've already replaced? I don't want to keep replacing the same things and not have it fix the problem.

View 6 RepliesJeep - Grandcherokee :: 2006 - Loud Engine At 65 - 70 Mph / No Torque
I have an issue with my 2006 Jeep Grand Cherokee v8 Laredo that has been bothering me for a little over a year now. When the temperature gets warm out (over 80) and I am traveling on the interstate up a long hill (65-70 mph, towards the end of my commute so about 30 miles in or about 30 minutes) my engine randomly begins to sound like I am in the wrong gear (RPMs do not change but engine sounds like I just changed to second) and I loose quite a bit of torque. I can maintain my speed but my engine sound horrible. After about 10 minutes of this my engine goes back to normal and I can accelerate without issue. Then randomly it goes back to being loud with low torque. To add to the the fun, if this happens at any time during the day, the next day when I start my Jeep the issue resurfaces and I have no torque for about 10 minutes (5 miles) then all is well for the rest of my commute (40 miles downhill). I had a diagnostic scan done and they found nothing wrong and I also just got both of my exhaust manifolds replaces but the issue continues.

I have a 2005 Jeep Grand Cherokee with 120,000 miles. The engine light came on and I took it in for service. The catalytic converter was defective and replaced. After service and 30 miles the light came back on. They erased the memory. After 35 miles the light came back on. So far I have returned 4 times and they cannot find the problem.
View 6 RepliesJeep - Grandcherokee :: Engine Sounds Like Its Turning 4000 RPM But Only When Cold
My Jeep sounds like it is in low gear and engine sounds like its turning 4000rpm but only when cold. This is so noticeable that dogs stare and pedestrians run for cover. Once the engine and drivetrain warm up a little, all is normal. The reality is that the engine is only turning 2500rpm and it is shifting, but the tranny doesn't feel like its grabbing very well. After just a few minutes driving, all is well and there is plenty of power. Fluids are all topped off and fresh.Is it time to warm this baby up and drive it to the nearest car lot?

My daughter's Jeep check engine light is on. Trying to get the car inspected so cannot be ignored. I think the code wasP0422, indicating it needed a new gas cap. We bought a new gas cap, cleared the code and it went away for a few days but before she could get it inspected, the light came on again. I saw similar problems suggestions were to get a better gas cap (we got one at autozone), or it could be something like a pump problem. We haven't taken to a dealer - it's a 2001
View 17 RepliesJeep - Grandcherokee :: 1994 - Check Engine Light And O2 Sensor Malfunction
So this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.

Jeep - Grandcherokee :: Distinct Clapping Noise When Engine Is Not Up To Operating Temperature
I noticed that my Jeep has been making a distinct clapping noise any time the engine is not up to operating temperature. It sounds worst on cold mornings, but becomes quieter as the engine warms up. The noise is RPM dependent, so I'm assuming it has something to do with the engine. The noise is not audible when the engine is idling in park, but quickly shows up as soon as I put the car in gear and add gas. My father and I think that a slightly loose rocker might be the cause of the noise, but we're not sure. A mechanic friend of his told him that our jeep has self adjusting rockers so it can't really be fixed without replacing it. I've never heard of such a thing so I'm having a hard time believing it. The really confusing part is that it only makes noise when the car is in gear and the engine is under stress, making no noise when it's just idling, even when the engine is revved. Since purchasing it 5 years ago, we have been careful to do regular maintenance on our jeep so I'm somewhat surprised by it.

My 99 jeep grand Cherokee 4.7 v8 4x4 will not start after 2 to 3 short trips. it starts up fine in the morning when the engine is cold but driving for a while while and I stop somewhere and shut the engine down for a few minutes it will not restart.. after I wait 10 to 15 min it start up ok.. Next when I'm driving on the highway, after 10-20 mins of driving, the engine stalls for 5-10 secs. and fires back up..I inspected all connections and the starter which were ok but I did find that the starter is soaked with oil dripping from the valve covers.. Could the oil be the problem..? Even causing the stalling out on the highway..?

2004 Jeep Grand Cherokee V8 4.7 L. Clock from right side of engine immediately after starting engine. Seems to be in rhythm with engine and increases in frequency as I rev. Gradually subsides over first 5 minutes and not audible after that. Recent small leak of transmission fluid, but I'm thinking that has nothing to do with this.
