| I have a 99 Jeep Grand Cherokee Limited, in the last few days i haven't been able to drive it. It starts, but after a few seconds it dies, has been always like that. What could be the possible problems. I thought it was the alarm system because before i had a problem in which the car wouldnt start, because i had lost the remote, but i'm just confused. Anybody has an idea what it might be? | |

2000 Jeep grand cherokee pushing 215,000. miles stills runs good but now at low idle in or out of gear it idles at or bellow 5,000 rpm sometimes so low that it stalls out. When I give it gas it runs good until the vehicle comes to a stop, then it dies. Temperature does seem to have an effect the colder the outside temp or if the eng is cold it seems to do it more often, It is not a consistent problem, but it occurs often. I took it to a shop a while back they said the check eng light threw out air intake censor problem, I replaced it twice each time it helps for a little while then goes back to same old pattern. Now whatever code its throwing out, the check eng light does not stay on all the time, its on and off. I am kind of tight on cash right now specially the way things are these days, Just getting the code read is going to cost over $100.00, am a diesel mechanic but gas engines are a headache! Does any body have any advice? Please

Replying to: jhonp (Nov 12, 2009 5:45 pm) when i let off the gas it might stall. happens 1 to 4 times a day. GOT NO CODES..... so far i have replaced the crank shaft sensor - it stopped stalling for 3 days $130 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 have done all the work myself. it was about 30 minutes for most parts NOT POSITIVE ON THE PARTS PRICES i just ordered a rebuilt ecu or pcu engine control unit. they program in the vin, mileage and part nbr so you gc will recognize it. $185 we will see when that comes..... SWAPPED OUT THE ECU AND THIS SEEMS TO HAVE SOLVED IT........ IF I WERE YOU I WOULD START WITH THE ECU alan |

Replying to: spriest (Jul 28, 2009 2:31 am) Below is the post i am replying to. "I had the EXACT same problem yesterday. My issue began after the vehicle was running. I heard a loud pop from the radio speakers and observed the voltage gauge floating while driving. After I got home and turned the Jeep off, it would not crank. No interior or brake lights, nothing at all that indicated I even had a battery connected. All of my gauges were pulsing and flipping over wildly with or without the key in the ignition and I could hear a faint clicking noise timed perfectly with the pulsing of the gauges. I let it sit for about an hour and it finally looked normal on the dash and sure enough - it turned over fine and all my gauges are back to normal. Even the pre-sets on the radio are still there. The only noticeable difference is that my clock on the radio is wrong. Did you ever find out the problem? Has anyone else encountered this problem and if so - what's my next step in troubleshooting this issue?" |

| last time mine would not start, the battery cable was loose..... just a little but it was enough, cleaned the post and the cable reconnected and it has been fine since. | |
