My wife's 2002 Jeep GC has just started having the problem of stalling at speed. Happens without warning and will start back up with out any signs of trouble. No CEL. Car has a 6 cylinder with 130k miles and is well maintained. Have been reading around this forum and have seen a few people post similar issues. I will look at the connection at the ECU tomorrow. Is this a common area of trouble?
View 4 RepliesI was driving my 90 Jeep Cherokee (automatic transmission) last night on the freeway when I suddenly lost power. The engine continued to idle (but roughly) but pressing the accelerator did not result in any increase in engine speed or vehicle speed. The car came to a stop on the off-ramp but I was able to restart it and limp along at idle speed for another few blocks until it came to a stop.
I suspected I may have run out of gas, despite the fuel indicator showing a quarter of a tank but after adding 2 gallons of gas to the tank it wouldn't start. It sounded like it wanted to but it wouldn't start.
So i have a 1999 Jeep Grand Cherokee Laredo, 4.7L v8 , it has been running good until as of lately. It has stalled or died on me 3 times, I can usually drive it for about 20 minutes, or travel short distances before it stalls out on me, the stalling is completely random, any speed/RPM. I have read everything under the sun about what could be wrong here, but where to start, have been hearing a lot about new Crankshaft sensors, TPS's , etc...
View 14 RepliesI have a 99 jeep grand jerokee... every once in a while it will just stall....it starts back up right away...no problem....battery is good... could it be the fuel filter? or the cranckshaft positioning sensor? or am i way off?
View 4 Replies2004 Jeep Grand Cherokee Laredo 4WD, 6 cylinder car is in Tallahassee, florida and when the temperature is warm outside in the spring and summer and the car has been driven for awhile and is stopped (like for shopping) and you try to start it again, it will not start. However if you wait for awhile like 20-45 minutes the car will start but will rough idle for a little while and then it will smooth out and go ok. This appears to be random and does not happen in the fall and winter months.
View 1 RepliesI have a 1992 jeep Cherokee sport that is giving me quite a headache & it seems to be getting worse. My jeep has 272,000 miles on it. Bought it used almost 5 yrs ago. Anyways, starting back in april when it started to get warm here in Pennsylvania, it started to do this thing where you'd be driving it at 45mph, the tac meter (thing that reads RPM) starting to bounce up n' down from 800rpm to roughly 1500rpm. It would bounce like that for every 2 secs while driving. Now, when i went to slow down to roughly 35mph & slower then that, it would begin to spit, sputter, jerk, & carry on & it shut off on me once!
It seemed like it got a mind of it's own too. When I come to a stop, it seems like it wants to give it more gas!!! There are acouple of times that I almost didn't get stopped & almost rear ended a couple of cars!! When you go to park it & let it run, it sounds like someone is pushing down on the gas & letting off of it every 3 secs. Again, it would go from 0rpm to 1200rpm then keep doing that til you shut it off. If you shut it off & leave it set for about an hr then, it'll run just fine for about an hr or so & then, begin to mess up!!
So far, I've changed, the plugs, plug wires, dist cap/rotor, 02 sensor, swapped a MAP sensor off of my moms jeep, (no change there) The last thing I just bought was a Ignition coil. Mine had cracks in it so, I thought it might of been that. NOPE!!! Still messes up. It seems like the hotter it gets outside, the quicker it wants to mess up. I've even got a can of carb cleaner & sprayed every vac line/hose that I can find. No change!!
One more thing. On cold/cool mornings, it'll start up & run just fine even with the bad coil that was on there.. No problems.
It started stalling out off and on. Thought maybe bad tank of gas and waited it out. Since then i have had the catalytic converter replaced. Ignition coil replaced complete tune up with new wires distributor and rotor button. Still stalled so they said fuel pump now that's been replaced and on my way home it stalled again.
View 9 RepliesMy 2004 Jeep Grand Cherokee (Special Edition) has been stalling on me for a couple months now. After 2 different shops I decided to take to the dealership after stalling on freeway. They had my car 2 weeks before they got it to stall and advised I replace the CAM and Crank sensor before replacing the PCM (main computer).The Crank sensor was replaced at the first shop, they said part had noted issues if after market. I had them replace the CAM sensor and am taking back to first shop to warranty the part and asked they use a factory part. My concern is it will continue to stall and the next step is to replace the PCM.
View 2 RepliesI have a 1999 Jeep Cherokee Sport v6. I have replaced the fuel pump, fuel filter, Battery, cables, alternator, distributor cab, and plugs and my car keeps stalling out on me. It drives and idles just fine but when I am driving or accelerating the vehicle dies, I let up off the gas and it restarts itself. When I hook it up it does not read an error code!! Not sure what to do next.
View 2 RepliesI have a 1999 Jeep Cherokee Sport, 4.0L (6 cylinder) that has 128,000 miles on it. Within the last two months it has started lurching 1 to 3 times per week. It only lurches once but always when the engine is hot and when accelerating. The engine light does not come on. It also loses power for several seconds at other times. Lastly, it has stalled two times in three weeks when I am coming to a stop. The spark plugs and air filter were changed last week. The injectors were also cleaned.
I do not have the skills to fix it and am taking it to the dealership which is very expensive - thus the money drain. Any thoughts on what might be going on? Or is it better to just cut my losses and look for another car. I would really like to keep this car for another year because I am in graduate school but am not willing to continue with the money drain.
1990 Cherokee 4.0 ... Well I've got a minor clunking somewhere under there that seems to vary with speed. now I have to figure out what it is. my working theories are wheel bearing, or one of the three hundred odd universals under there. perhaps a brake shoe or the transfer case. This is my first 4wd, so I don't know about transfer cases.... there is also some kind of weird double universal under there, I can t remember the name off the top of my head.

Problem "Stalls at idle and at hwy speed" sometimes starts right up and sometime will not start. Sometimes it will lose acceleration but engine will still be running and you can punch the gas and it will go again.
It has been in the shop for most of the last 2 months. Driven in 3 times and hauled in twice.
Low mileage 70,000 - has been great until now - serviced regularly.
Did get new fuel pump only about 10,000 miles ago do to starting problem but in that case it just did not start.
Independent shop replaced distributor cap, rotor, coil, fuel filter. No codes and couldn't duplicate problem.
Jeep dealer replaced fuel pump (they said wiring problem), O2 sensor, engine module no help, they asked us to pick up car because it ran fine. It stalled within 2 miles of shop.
We replaced gas cap just in case.
Limped back to shop to replace crank sensor as it was suggested several places. Ran fine for about 45 minutes then back to old tricks. Relays have been checked. Still at shop trying to trace problem. At least nobody is saying they can't duplicate problem as it now stalls all the time.
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 own a 2001 Jeep Cherokee with 104,000+ miles. It runs great and doesn't have any issues. However, i started it up this morning and the check engine light came on. Should this be concerning? I haven't done any real maintenance on it since it runs so well. And i guess that's my other question - what should i do to the Jeep to keep it running for another 100,000+ miles? Spark plugs? Timing belt??

View 2 Replies2015 Jeep Cherokee 2.4 engine. Engine is very noisy at idle. Not noticeable when driving. It has variable valve timing or valve lift. I also has a big black hat on the engine, I wonder if that is supposed to quiet the engine some, if so it isn't working.

I have even traced the cooling fan relay wire to PCM, all OK.

Jeep cherokee 4.8L 2000 .....
For three years now my 2001 Jeep Grand Cherokee Laredo will whistle. Usually when the engine is cold. When the vehicle is idling in the driveway or at stoplights, whenever I take my foot off the accelerator it will whistle too. The only time it won't whistle is when the gas pedal is being pressed. I've had it to a number of different shops to be serviced but once the car is inside or the engine is warmed it will never whistle for the mechanic looking at the vehicle. I've been told that it could be related to the IAC motor.
