Jeep - Grandcherokee :: Stalling - No CEL Or Error Codes
Oct 18, 2010
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.

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.

I am having a problem with my 1996 jeep grand cherokee. When I stop at a light and I am in drive, it wants to stall. If I am in park or neutral - no problem.

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.

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.

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?

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?

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?

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.

ODB2 Code: P0300 - Multiple Miss-fire
I have an issue with my Jeep Liberty. It started idling rough with no error codes. about a week later it through the Multiple misfire code. I started by replacing the spark plugs. The old ones were from 20K miles ago and still looked good. Replaced them anyway. I still had the code. I put K44 fuel injector cleaner into the tank and drove it home (2 miles.) The next morning I started it and went in side because I had forgotten something. I came out to extremely thick black smoke. It went away after about 2 minutes, the computer code cleared, and the engine idled perfectly. About 2000 miles later the car is once again idling poorly. I added K44 again and for that tank of gas it ran fine, no code. Once new gas was added it threw the same error code and idles very roughly.
So here are some basic info pieces:
1. 8 tanks of gas from 8 different locations.
2. Adding K44 has shown a direct improvement both times, but more significant the 1st time.
3. New spark plugs
4. New coil packs
5. 2005 Jeep Liberty - 3.7L V6 at 99,872 miles
6. Hopefully unrelated is that the car has a small radiator fluid leak I haven't found. It requires 1/2 gallon every 2K miles or so.
There is no knocking sound, it just sounds like there isn't enough gas. Car responds fine to accelerator. Above 10mph car seems to drive smoothly.

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.

My wife says our 2002 Grand Jeep Cherokee very rarely hesitates as it moves from first to second gear (once every week at most). I've never felt the problem, but she says its happens when from a dead stop into 2nd gear. And she said there are no other times when the vehicle hesitates (fine in every other gear). No other weird noises and the power seems fine. Its an automatic transmission and I've had the fluid and filter changed recently. What it is? Transmission? It is due for some new spark plugs... any chance it could be that?

About a year ago the oil stopped showing on the dipstick of my 95 Jeep Grand Cherokee. It is the original dipstick. I have changed the oil, filled it according to manual. It runs well, engine has no ticking (unless its low on oil, then I add a quart), pressure is fine. Just no way to check the oil !The tube is still attached from looking at the outside.

Last summer my wife's 2000 Grand Jeep Cherokee began shutting down while driving (electric stays on) on early hot days after about 40min of driving; even when the AC is off. About 10min later we can restart as before (before that it won't even crank). Over the winter the problem went away but returned again this spring/summer with the hotter weather (>80C). Its not the no battery or alternator and no one can seem to figure out the problem.

I have a 95' Grand Cherokee, V8 5.2L. Recently, it started overheating and was diagnosed as a head gasket issue at a shop. I ended up replacing the head gasket, thermostat, and water pump. (The radiator, top radiator hose, and radiator cap were replaced within the last year as well.) Despite the repairs, the coolant in the reservoir does not move. The Jeep overheats and there is a squealing noise coming from what may be the water pump. There is also a slight leakage of coolant near the water pump bypass hose, but does not seem to be coming from the hose itself. What else am I missing?

I'm having an issue with my 93 Grand Cherokee with 193k miles.
The RPMs will fluxuate and even drop to 0 at times and the whole Jeep with shudder and shake and then the RPMs will return back to normal. It could just drop down once, or several times in a row. I've even had it completely die a few times and I'll have to restart it. It's the worst when idling or driving slowly, like through a drive through or a parking lot, but the Jeep will still give a small jerk at times during acceleration as if it's trying to do it but can't completely.
I know next to nothing about cars but I have a friend who has assisted me with few things. We changed the fuel filter which he said looked like it may have been the stock fuel filter. He hooked up his compressor and blew all kinds of black garbage out of it and concluded it definitely needed a new one. He told me just to run it and see how it did, which it did fine for awhile but today it seemed to be acting the worst ever with it shaking and shuddering and trying to die but it didn't. He also looked at the spark plugs and told me that while they were aged they didn't look bad enough to be worth the money replacing...

Went over a bump on the highway the other day and heard a loud noice as if I was dragging something under the car. I checked but nothing was there. It reminded me of putting a baseball card in your spokes of your bike when you were a kid. It happened twice and the weird thing is that if I put it into reverse and drive about 10ft The problem went away. But something still seems loose and it sounds like it will happen again. I was googling this and it seems like the noise was around where the center differential or drive shaft?

'95 jeep grand cherokee 4 whl drive. No previous starting problems, but last week suddenly wouldn't start (lot of grinding) and check eng. light came on. Had it towed to shop. They replaced battery and battery cable. Worked fine for 2 days, but this morning barely started (again grinding noise) and check eng. light came on again. What might be wrong?

I have a 1999 Jeep Grand Cherokee Laredo. Some of the gears are intermittently "sticking". When I get up to 60 m.p.h., it's supposed to shift into the next gear, but sometimes it won't and the vehicle starts lurching as it comes up against the "shifting wall". Other times it won't downshift, so I leave a stop light in 2nd or 3rd gear. The lurching only occurs for the gear at about 60 m.p.h., unless I put the gear selector into "2", then it sometimes lurches there too. Several mechanics, including a transmission specialist at a local Jeep dealership (who charged me for 2 hours of "diagnostic time"), couldn't determine what is wrong. I did a transmission fluid flush, but that didn't work.
