Jeep - Grandcherokee :: Oil Pressure Goes Low After Driving For About 30 Minutes When At Idle / Low Speed
Dec 20, 2012
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?

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 problem with my jeep grand Cherokee Laredo 5.2v8 losing oil pressure when the engine reaches normal operating temperature. the jeep sat for 2 years but we got it to run. when normal engine temperature occurs, the engine drops oil pressure and stalls. I have changed fuel pump,oil pump and oil pan gasket. also ran a cleaner through the engine. it doesn't matter if its winter or summer. the only way I can keep it running is to keep my foot on the gas pedal. if I don't do this the jeep stalls. a mechanic said it was the bearings. I don't believe this because there is no knocking noise when the engine is running. it has 103663 miles on it. it has just city and highway miles on it. never has been off road.

So, I have a 1995 Jeep Grand Cherokee (Orvis edition) with about 270,000 miles. It still runs great and has been really useful in the snow this winter. A couple days ago the power steering pressure hose blew. My mechanic wants to replace it, but I can get a replacement hose locally. Is there any reason I shouldn't just do this myself. Do I need to worry about the fluid sprayed around the engine? The serpentine belt is only a few months old and squeaked only a little on the three mile drive to get it home.

I have a 2009 Jeep Grand Cherokee. One of the tire valves has a slow leak. I figured I could get a new valve. But, instead, the guy reminds me that the valve has the pressure sensor built in. He could put in a regular stem, but then the light on the instrument panel would never go out and I'm assuming I couldn't get through inspection like that.

New quirk in my '04 Overland, 133K miles. When driving, it feels like I am getting some "wrap up" in the drive line. What I mean is that, when there is even the slightest amount of throttle pressure, and it is let off, there is a perceptible slight pull or surge feeling to the right. When even light throttle pressure is applied again, it will pull back left again. No driveline noises, clunks, shimmies, etc. , just the feel of the car sort of torqueing when there is pressure added or removed from the power train. It is more of a "seat of the pants" feel than in the steering. My guess is that it may be a suspension link or bushing in the rear ended gone, although I do have some fear about maybe the limited slip unit in the rear differential acting up, as I hear these can be prone to issues.

I inherited a 2008 Jeep Grand Cherokee from my late father and it seems like whenever the temperature overnight drops below a certain level, in the morning the low tire pressure light pops on. I never encountered this problem with any other car I owned, is this something inherent to SUV's with all wheel drive?

I have a Jeep Grand Cherokee 2001 with about 150,000 miles. About every other day my car will shut off while I'm stopped at a light, stop sign, etc. The strange thing is that the radio and lights (stuff controlled by the battery I assume) does not turn off with the engine. It seems the frequency with which this happens has stayed about the same, and I haven't been too worried until yesterday when I went to start my car and it would not start. It just kept revving and seemed like it was very close to starting.
I opened the hood and saw a lot of corrosion on the battery and luckily I had a coke in the car. After pouring some coke and wiping away the corrosion, the car started up. I have had no problems since I did this yesterday. But like I said, my car engine seems to turn off without warning so it could happen next time I drive. If these two problems could be linked, that is the corrosion on the battery could have caused both the car not starting and the engine shutting off when the car is idling. I took to a mechanic about a month ago and they couldn't find anything wrong with it and, of course, it didn't shut off when they drove it.

I am experiencing engine stalling while driving my 1996 Grand Cherokee, after it went low on gas about 6 weeks ago.

I have a 2002 Jeep Grand Cherokee with 207,000 miles that has recently begun stalling while driving. Typically stalls at rest or when coming to a stop, and for a time it would re-start without issue. More recently it won't start readily after stalling, but will eventually start with enough key-turning persistsence. The check engine light comes on only after stalling and not restarting (but was not on previously), and often shuts off after a few miles of smooth running. I took it to my local mechanic who ran the computer codes and reported a malfunctioning cam shaft position sensor (i question if this was the casuality of other problem), which they thought was the source of the stalling, but after replacement it is stalling more than ever. It seems like the local mechanic group won't diagnose anything in this high mile Jeep without a computer code and I am reluctant to bring it back.
What is the cause of the stalling / starting issue? I may be way off but was concerned about a clogged fuel filter or fuel injection problems.

Jeep grand cherokee 1999 stalls while driving. Replaced crankshaft sensor. Check engine light indicates oxygen sensor issue. After 5 to ten minutes car starts again, most of the time. When the car fails, engine cuts out and gas gauge points to empty. Only starts when the gas gauge functions properly. still having this problem.

I have a 1996 Jeep Cherokee and am having a problem my mechanic can't figure out. Sometimes it starts, sometimes it doesn't, heat or time of day has no influence. It even dies while I am driving. While driving it will die and start again over and over. Sometimes it runs fine with no problems. Have had this problem for 1 1/2 years now. Have relpaced rotor, dist cap, pick up coil, tune up, computer sensor, fuel filter. So far nothing has worked.

My jeep will randomly just loose engine power the rpms just drop off completely. Sometimes the whole car goes off but not always sometimes just engine power then it wil kick back in after a few secs...... I have been looking everywhere see that it looks like a common problem but whole bunch of fixes.

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?

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.

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.

1999 Jeep Grand Cherokee Laredo, 4.0 in line 6 Cyl misfires when driving. I bought this about 2 months ago (200,000 miles), and when i first got it it was acting like it was misfiring when driving above 60 mph( did get codes P0301 cyl 1 misfire, and P1391 CPS) . it started to act the same way just driving in my small town. so i ended up changing the ignition coil pack and changing spark plugs, i also replaced the CPS (camshaft position sensor). and was still acting the same way. I located a TSB that said there might be a carbon build up problem preventing valves from rotating and seating.
So I used seafoam and clean up the Top, and drove it in low gear at 4500 rpm for 15 seconds or so 6 times.. initially when doing this it was cutting out (jerking) when rpms got up there. after doing this twice with about 3 weeks in between never had a problem in town with it acting up running like it should from what i can tell..
Then i took a road trip, and a 60 mph was fine, 70 mph it was fine.. so i thought it fixed the issue and all good.. but about an hour into the drive it started acting up again.. unexpectedly cutting out for a second here and there, and usually when going up hill, and when got to destination about another 40 minutes, coming to a stop light i noticed it when stopping it was running pretty rough like it wanted to die out but never actually did. never got any more check engine lights either. I'm kinda at a loss at what the issue might be, and what i need to do to fix it as i really like the vehicle

Over the past several years, this has happened maybe once a year. However, in the past three months, it has happened three times. The shut down always occurs at low speeds. In each instance, I had taken my foot off the accelerator and was coasting to, say, make a turn into a driveway, or enter a parking deck, or move slowly in traffic. I'll realize what happens when i notice that the steering wheel is locked. And then that nothing is happening except the car rolling.
Every time, the car has started back up, immediately, without incident. (Of course, I have to stop the vehicle and put it into Park before restart. Only once have I had the problem where someone was right behind me.) Several mechanics have been unable to figure out what is causing it because this never leaves a code in the car's computer. What is going on and what he might service to fix this?

My 05 Cherokee has begun to jerk while driving. It's only just a jerk or two and then it smoothes out and drives fine. It only happens while driving never from a stop.It is also hesitating a little while starting. It always starts but I have never had this problem before. Not sure if the two issues are related or not but thought I would mention it.

I have a 1996 Jeep Grand Cherokee Laredo. While driving the other day the steering wheel totally locked up. It was not like just losing power steering; you could not turn the wheel at all. I had the same thing happen 3 years ago and knew that if I turned off the car and restarted it the steering would unlock. I did that, it unlocked, and I continued on my way. A few blocks later, the wheel locked up again and this time the engine died after the wheel locked up. A few blocks more and it locked up a third time, the engine died, and I could not get the vehicle to restart for several minutes. The engine would turn over but it would not start. After finally getting it to start I pulled into a parking spot and called a tow truck. The mechanics have had it for several days and can not find anything wrong. It will not repeat this behavior and no codes come up on the computer. When this happened 3 years ago the same thing happened. The mechanics had it for several days and could never find anything wrong. I've been lucky so far in that this has only happened at low speeds and at places where there was not a high volume of traffic.
