Check the string for the same problem on the 1997 model, especially #6 by jhartgc. Lots of helpful info there. I had the same problem on my '98, tried all the usual fixes, crankshaft positioning sensor, ignition coil, etc., but the fix by jhartgc "pretty much" solved the problem. When it started to hiccup and occasionally stall again, as well as retightening the bracket, I also blew the connectors clean with compressed air and sprayed them with WD40... no problems for about 6 weeks. Then I found a more permanent solution by blowing my head gasket, so it's off to the junk yard and no more stalling problem!

my jeep is a 1998 4.0 it started out just sputtering but if you pushed the gas pedal to the floor it would take off and run like hell but when you let off it it would start all over again. then one day it just quit. it wouldn't start again, ive replaced the crank sensor, the cam sensor, plugs, wires, cap, rotor button coil. it should be a recall but the manufacter refuses to do anything about it.

The car would stall while driving. Two times the car had terrible backfire and blew up two exhaust systems. Spent thousands trying to get problem fixed, including re-flashing the computer. I eventually found dyingjeep.com who explained the defect. I purchased washers and longer screws to mount the PCM so it wouldn't short out. Also used large tie strips to hold in place. Fixed the problem immediately and have been using the car for over a year with no issues.

My 1998 Jeep Grand Cherokee has been nothing but a pain in my ass. I will start by saying death trap. OK anyway, about 3 months into owning this recycled pile, I was driving on the freeway 65+ ,when out of nowhere this spawn of hell 1998 Jeep that was sh*t out by Chrysler, its engine just stops running. The gauges are having a spaz attack. All the idiot lights are flashing. This jeep was trying to end my life.

Holy sh*t! Wow. the car has now stopped halfway on the freeway because there's no room on a freeway to break down. Nice, right? Moving on... here's whats really crazy ... this Jeep from hell started right up. Really. Now after cleaning my drawers and telling myself just drive like your miss daisy, I headed for home.

Now really for like a week, nothing. It was like "who did I piss off". Weeks after Jeep just dies on the way to store. Great thing for me. Its 30 miles hour. Bad. Now Jeep don't start. After 7min, Jeep comes to life, but now its running like the price of sh*t. It is the engine running rough. I wanted to just leave it, but got it home where I should have let it die or maybe I should have filled it with sh*t and returned it to its creators, because no matter what you tell them, its not their problem. Well if there's more like me, that own a heaping pile called a Jeep, we need to band together and make our voices heard. Are lives are worth that?

So yes, I did fix Chryslers heaping pile, because it was my only transportation. So here's what I can tell you if your Jeep is running rough or just quits running while your driving. You need to pull all three connectors out of your Jeeps computer, that is located on the left side passengers side and replug them and restart Jeep. Let run and computer reprogram also really important. If still runs the same the connectors you're plugging back in are crap and wiring harness may have a break in it. Do one step at a time. Also you can repair wiring harness but its takes time and patients you can also get one from a scrap yard just check it out before putting it in your Jeep. . Now get rid of it .

The car stalled while driving on the freeway. It just "shut off". It was very frightening. I was on the 110 N near downtown Los Angeles. I took it to the dealer in Santa Monica, they couldn't find a problem. It did this in Oct. 2010 while driving on the 90. I had a 1/2 tank of gas. I saw the gas gauge suddenly go from 1/2 a tank to empty and then wham! The car just shut off while I was driving on the freeway! Took it to the dealer (La Brea Jeep), and again, the dealer did not find the problem. He changed the computer box, but it still stalled out while driving. The car is dangerous and I can't find anyone who can find the "problem". Why is my car shutting off when I drive? I'm scared.

Update from Jul 18, 2014: The car had a strong smell of gas each time coming from outside of the car.

Grand Cherokee V8

  • Automatic transmission
  • 156,000 miles

Hello My Name is Trenia ,I brought a car that was for my budget while in school , which is a 1998 Grand Jeep Cherokee V8. I guess I have this car about a year and half and In the beginning it was a reliable vehicle that had minor cosmetic problems, really wasn't a problem . Until the day I was driving home from work and the car was in motion and it just stalled while making a turn on my street and would not turn over, .I had to get someone to push the car in front of my door . I had several mechanics assume it was the sensors to the crank and cam sensor, which was changed then a new coil was installed, followed by an ignition switch check that was still good, to getting a new programmed ECM put in.To get no turn over in the engine trying to start, but then he came with a computer that read it's the sensor again. We changed the sensor that was located in the distributor. It started up.and after first trip we recolonized tapping sound. Every male in the family said it sounded like the valves were tapping then a friend got in touch with another mechanic that says it could be electrical because when he move the wiring around the distributor it's making different sounds as well. So my question is simple - has anyone came across a recall that has these issues? Or have you solved this adventure I seem to be taking?
