Jeep - Grandcherokee :: 1996 - Random Stalling / Restart Sometimes

96 grand cherokee 4.0L- Randomly stalls or maybe I should say it randomly operates. Hot or cold it doesn't matter. Sometimes it will restart sometimes not, This has happened before and I replaced the computer- twice. It works fine for a while but I end up here again. What could be frying the computers. Is there a way to check the computer to see if it is malfunctioning?

Jeep - Grandcherokee :: 2002 - Stalling While Driving

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 - Grandcherokee :: 1996 - While Driving It Will Die And Start Again Over And Over

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.

Jeep - Grandcherokee :: 1996 - Steering Wheel Locks Up While Driving

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.

Jeep - Grandcherokee :: Stalling - No CEL Or Error Codes

We just bought an 1998 JGC Laredo and it ran fine for the first week, then started stalling. Our mechanic originally thought it was the CPS (Crank Position Sensor) and replaced it, and we thought that solved the problem since it ran better. They made a comment at the time that the previous owner had been "chasing this problem for a while since most of the ignition parts had been replaced (computer, CPS, coil, etc)

In a few days though, it started stalling and we took it back to them. Note, no error codes, and the check engine light never came on. After scratching their heads for a while, the finally did a "wiggle test" on the wiring and found that one of the plugs on the computer was loose, and the plug itself needs to be replaced. I can easily make the car stall by just pushing down on the plug a little.

I temporarily have it working much better by using wire ties and securing the plug down to the computer, but at some point I will need to replace it. Make sure if you replace it, you get one from a Jeep with the same S/N on your computer. Jeep was very bad about making changes to the computers and systems and you could easily get an incompatible one.

Jeep - Grandcherokee :: 1994 Intermittent Stalling And Now No Spark

The problem began with intermittent stalling and now the Jeep will not start at all (no spark). I have had the cap, rotor, primary ignition coil, crank sensor, cam position sensor and PCM replaced without any luck. The repair bills have been brutal. The garage has given up.

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 :: 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 :: 2001 4.0L Started Stalling When Coming Up To A Stop

I have a 2001 Grand Cherokee 4.0L with 215xxx miles. It just started stalling coming up to a stop, but then it starts right up no problem. Engine idles a little rough and the gas mileage has gone down somewhat. The CEL came on a while ago, and the auto shop checked the computer code and said it was the neutral safety switch. I brought this up with a friend who had the same problem and he rebuilt his and said it was easy. So I was going to attempt it, but I can't find the darn thing. @ questions:

1)where is it? and
2)could the NSS be causing the stalling?

Jeep - Grandcherokee :: 1996 Will Turn Over But Not Start / Gauges Are Dead

I have a 1996 Jeep Grand Cherokee with 152k miles on it. Recently replaced battery. All of sudden yesterday, engine will turn over and try to run but sputters out and dies after about 30 seconds. Cannot maintain idle on it, and none of the gauges rise when you turn on the ignition, so that you cannot see the RPMs and the gas gauge reads empty even though I filled it up two days ago. Tried to start it today and saw the same problem but with no sputtering, engine dies within seconds now.

Jeep - 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.

Jeep - Grandcherokee :: 1999 - Power Cuts Out When Driving?

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

Jeep - Grandcherokee :: 2005 - Stalls / Cuts Off While Driving

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?

Jeep - Grandcherokee :: 2005 - Hesitating To Start And Jerking While Driving

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.

Jeep - Grandcherokee :: Hesitating While Driving Then Starts Rattling And Dies

I have an '03 Jeep Grand Cherokee that has twice had issues with hesitating while driving (like it's not getting gas--tank is full), then starts rattling, then dies. I had it towed to the shop 3 weeks ago. "loss of cam or crank sensor misfire codes found loose connection at pcm, connector 4, re-attach connector to lock position, erase codes". Picked it up after work was done. When driving it to work two days ago, the same exact situation presented. Had it towed again to shop. They're saying they ran it all day and cannot get any codes to come up and that 90% of the time it's the cam sensor. He also said 1/3 of the time (math issues) it's the computer. How can you know if it's the cam sensor or the computer?

Jeep - Grandcherokee :: Completely Shut Down With No Warning Signals When Driving In Traffic

I have a 2005 Jeep Grand Cherokee Laredo. I took it to the dealership on June 30, for a routine oil change and other maintenance that was due. They did a cooling system flush, and oil change, a power steering flush, and a brake system flush, along with a multipoint inspection, and replaced the belt and tensioner. On July 18 on my way to work in traffic, the vehicle completely shut down with no warning signals. Shortly after the check engine light, the oil light came on. Until then, I had not noticed any warning lights.

At this time I reached down to get a bottle of tea from the passenger front floor board and noticed a slightly oily pink brown liquid on the plastic floor mat. When it was towed to the dealership, they tore the engine apart and reported that the engine overheated, the valve seats came off, the valves hit the pistons splashing metal onto the cylinder walls and requiring an engine rebuild. Is the dealership responsible for not having discovered whatever problem caused the engine to break down? Or causing it somehow during the maintenance on June 30? They feel it is not related.
