Jeep - Grandcherokee :: 1999 - Power Cuts Out When Driving?
Feb 10, 2013
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?

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.

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..?

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 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 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.

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.

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.

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?

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?

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.

I have a 2014 Jeep Grand Cherokee with a start button and key fob and all the new electronic controls. While driving recently, the dash electronic console display turned off (I thought the car engine had died). It spontaneously lit up again, but all the warning and check engine lights were on. The car would only move forward very slowly (as if stuck in 1st gear). When I was able to pull over safely to the side of the road out of traffic, I was unable to get the car out of drive into park. Because it wasn't in park, I could not turn off the engine! I was afraid to take my foot off the break, fearing it would begin moving, so I couldn't get out to disconnect the battery. Is there any way in these new technology cars to force the engine to shut down in the event the electrical system is malfunctioning?

My 2004 has suddenly decided I should drive with dome lights on all the time, as if starring in an episode of COPS. Seems something is reading my driver door is not closed, even though it is closed. Besides lights on, unable to use controls to roll down window or lock vehicle. Also, there is now a whistle emanating from the bowels of this silver beast. Seems back near the fire wall or underneath. Sadly, this 2004 JGC does not even have 150,000 miles and things are going south for the winter to retire in Florida. Had one form 1993 and it lasted over 400,000 miles and my 1999 had 250,000 before I met Mr. Ice. On top of these goings on's the right rear wheel is causing a scraping noise, but not 100% of the time.

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.

I've replaced fuse underhood and fuse inside door panel. I've read about in the glove box there may be a fuse there for power windows? I removed the glove box panel to find 4 relays. Nothing is marked on these relays or panel. I read the numbers off these four relays inside the glove box to the clerk and she did not show any such thing on her computer for my vehicle. can a person pop out the main driver door switch and replace that?

I bought my jeep about a year ago, and have had major problems with the computer system. My car wouldn't start for days on end, and then one day would start right up. I just went ahead and replaced the whole computer, wiring, ect..and it ran fine for about 4-5 months. Once and a while the check engine light would come on, but nothing happened. Then one day my car died right in the middle of the street when I was driving it. All the lights in the dash go off and it just stalls.
Sometimes it starts back up immediately,and others I have to sit for a god 15 minutes. Sometime it'll do this 5-6 times in a day, others it won't do it at all. I noticed it does it more often when it's hotter outside. I got the check engine light checked (it comes on only once in a while) and the code said it was a cylinder 6 misfire. I took it into the shop and the checked my spark plugs and said they were fine, and they couldn't find anything. Could this be related to the new computer? What I should have checked on it?

It was running on 7 cylinders and had not been tuned in probably 50,000 miles or more. I recently bought it at auction. Changed spark plugs and 1 coil for the dead cylinder. Rear cylinder on passenger side was not firing. Compression test shows 150 psi that cylinder. Fairly loud mechanical pecking from that area which was isolated with a stethoscope. I suspect a flat cam lobe or broken rocker arm.
