While driving the engine stalls, and sputers and jerks, the problem is very intermittent, Before the engine stalled there was a check engine light on with a code which was driven for about a year wirh no problems, it had a couple codes of which one was the fuel cap which was replaced with no aid to the light, Recently while on the highway going about 60 mph the engine stalled, I noticed the first time the speedometer went from 60 mph to 40 mph in about a second plus the RPM gauge went down quickly as well, Thre last time it stalled there was a little more than one half of tank of gas the fuel gauge went to empty during the stall and few seconds later the fuel indicated correctly, So far I changed the fuel filter and the spark plugs and cleaned the throttle body
Do you

Well almost $1,000 later I traded in the Jeep while still having intermittment problems. Luckily for me the problem did not occur when I traded it in. After a local good mechanic did not fix my problem I did bring to the "dreaded delaer" I was first told it was the computer hte PCM that was bad, so I had them to change it. Parts and labor of $420. Then before fixing the problem they did tell me that they need to fix the computer before finding out if there is any ohter problem. Once they changed the PCM they then told it was the fuel pump. Which they wanted another $500 for. So I had my mechanic change the fuel for aprox $300 total. After the fuel pump was changed then I had a new code for Camsahft sensor which
I changed myslef form Autozone for $30. To make a long story short the Jeep still has a mind of its own. My mecanic seems to think the dealer never changed the brains. I think there a an intermittent short circuit. The reason I think that is when the battery is reconncted is the cable sparks alot indicating to me short. Good luck.

My 2004 Jeep Grand Cherokee 6 cyl has a weird problem my techs can't diagnose. While driving on a daily basis the tachometer and speedometer will dip down occasionally when I hit a pothole or bumpy road. No other gauges are effected. After a while the engine will stall when this happens, usually causing loss of power to the engine, and eventual shutoff of the engine. The check engine light never lights up, and when scanned for codes none exist and none are pending. As a matter of fact when this condition occurs the entire computer is reset to 0 engine starts since last scan. The tests are also showing not ready and no drive cycles completed. The wiring harnesses and connectors visually look OK as far as we can tell, and when testing the 5V and grounds at the terminals while parked things look good at inspection. We suspect somewhere somehow some component is shorting out the 5V but no idea where to start. Or we could be completely off and need your expertise.

Look for the engine harness damage at the left rear head stud I have seen several rubbed thru and cause this condition. It is usually poked thru the harness tubing.

Also, check the ground on right side of the block. Remove, clean and reinstall.

Harness did show signs of wear through tubing, but no sign of wire insulation failing. Did rewrap and protect just in case.

Also replaced the crank sensor as proactive step since they fail so often and it was only 30 dollars.

Really won't know until road tested for a few days

But thanks for the good advice

Grand cherokee stalls or dies out. With no codes
1998 and earlier.
1) Check your connections at the ECU (ENGINE CONTROL UNIT) may be called
the PCU (POWERTRAIN CONTROL UNIT) on the passenger side firewall.
On 1998 and earlier the 3 plugs sometimes get a bad or loose connection.
It is ususally the one closest to the fender, unplug and spray the connections with a cleaner
and replug. You may even have to wrap a zip tie around the back of the ECU and zip it to
keep the plug in tight. Take it for a test drive.
2) This may also be the problem. It is going to sound screwy, but there are torx screws
on the 1998 and earlier ECU. Back them out about a 1/3 of a turn. The screws are too long
and are causing some kind of short in the connection. Take it for a test drive.

3) FOR 1999 AND LATER (this was my problem)
I had same problem. 87,000 2000 grand cherokee 4.7l
when I let off the gas it might stall. Happens 1 to 4 times a day.
THERE WERE NO ENGINE CODES
I tried all the above but no luck.
So far I have (not sure if I remember the prices right)
- replaced the crank shaft sensor - it stopped stalling for 3 days $45
- cleaned the throttle boddy free
- replaced the throttle position sensor $72
- replaced the idle air control sensor $132
- replaced the map manafold airflow sensor $125
no luck it is still stalling..
By the way I did all the work myself. It was about 30 minutes for most parts.
I finally ordered a rebuilt ecu or pcu engine control unit. They program in the vin, mileage,
and part nbr so your grand cherokee will recognize it. $185 (rebuilt - off ebay)
IT CAME AND THAT SEEMS TO HAVE FIXED THE PROBLEM.
IT HAS BEEN A WEEK. SO FAR SO GOOD

I have a 2004 Jeep Grand Cherokee. Lately it has been stalling out on me when my foot hits the break. I have also been driving around with the malfunction indicator light blinking for a couple months. I brought it to be look at, but the mechanic stated there was nothing he could do becuase the light was not on at the time. He suggested changing the spark plugs and cleaning out the throdal. Could my problem be the cat. Converter?

Hi:
The problem could be many things. However, since the light was on, there should be a code saved in the computer. Take it to a nationally recognized parts store and have them scan the computer for codes. Even if the light isn't on, a code could be saved.

Let me know what you find.

After I start the car, it shuts off within 2 seconds. It did this for about 20 times in a row. On the dashboard a yellow symbol which looked like a key inside a no smoking symbol. We also heard ticking noises from inside the engine or behind the dashboard immediately following the engine shutting off. Could there be something wrong with the security system? It's almost as if it shuts off within 2 seconds to prevent someone from stealing it. Our dealership wants to put in a new battery, spark plugs and give it a 30,000 mile tune up. Is all of that necessary?

Please Advise

TELL them to fix the start problem under the warranty FIRST!
If you still think it needs a tune up after that, bring it back to them at a convienent time.
Your battery isn't that old yet. You don't have that many miles on the car yet. They should be able to get it to start and run without a major tune-up.

That's why they call them stealerships.

I Have a Viper remote start system. Recently It will start and run for about 2 seconds then die. If I let it continue to start, it will do this 4 times. Then when I get in and start it with the key, It will take a couple of seconds to turn over.

If the remote start requires the tach wire signal, check to make sure it's connected and programmed.I don't know as much about these as the specialty shops, but I do know that! This is especially true if the car will start with the key and run OK! Some are tachless systems and need a time limit on cranking. Check with the manufactures web site or the local Viper guys! They may help.

I purchased my 04 Jeep in November and all was well until 3 weeks ago. My son called me and said the Jeep stalled out on the interstate so he pulled over. He said the engine stalled and odometer dropped to 20 mph while he was going at least 70. I went to his aid, started the Jeep and it ran fine until last week. It is now stalling out with gauges going crazy. Took to Jeep Service and have driven, seen the problem but do not know what is causing the issue. This morning they called and said that the problem will not come back and that are at a loss.

Suggestions.

This type of thing happened to me while still under warranty bought 2004 jeep new back then. After fighting with arrigo dodge for weeks, they finally found the problem. The two things, needles, did not line up right. Something like the airflow and gas flow?

I have a 2003 jeep G/C 4.0 It shuts off everyonce ina while while driving. The engine light is on. Codes are 0455 and I think 0442. Had my shop look at twice. Pressure tested everything, replaced relays, test fuel pressure and replaced fuel pump relay. Still does it, Will start back up after like a hour of sitting.

Your problem lies in the evaporative control system on those Codes-try have it smoke tested-Also when it stalls don't wait for nothing look for fuel and spark
