#339 of 1069 Heating At Idle
Aug 27, 2008 (7:07 am)
I have a 1998 Jeep Grand Cherokee with the 6 cyl 4WD. It has 147,000 mile. Radiator was replaced at approx. 110,000 miles. No other replacements have been made to the cooling system.
It has always run with the temp gage just at the "Half way" mark on the temp gage. Lately when I am stopped at a traffic light, or just idling, the temp gage slowly creeps up. It has gotten close to the red mark on the gage, but never hit it. When I start driving again and the air is flowing thru the radiator, it cools back down.
Any suggestions to keep it from heating when Idling???

#342 of 1069 Hard to start and keep idleing
Sep 04, 2008 (1:53 pm)
I have a 99 Grand with the 4.0 and 125k, I go to start it and it would not turn over. I recently replaced the battery. Everything turns on electricly and I can hear the engine cranking but it will just not turn over and run. However, if I push on the gas pedal as if I'm reving the engine or as if it wasn't fuel injected I can get it to start. I must hold the idle speed, usually around 1000 rpm, for maybe 30 secs. or so to make sure it'll stay started. If I don't physiclly hold the gas to keep it running it just stalls out. Once it's running for the first few minutes the idle is very low, around 400 rpm. In addition to the problem this happens totally random and without warning. Have had it happen as many as 3 times within a week and have gone as long as 1+ months between it. Once it gets running it's perfectly fine with no difference in performance or ride. Someone suggested the fuel pump. Anybody with any suggestions?
#344 of 1069 99 JGC sudden/intermittant stalling problem
Sep 07, 2008 (8:33 pm)
Help! I have only had my jeep since May. I started with a overheating problem, which we easily fixed with the fan relay switch.
But, within a couple weeks it appeared to be "possessed". Started cutting out while driving, so quickly it was hard to know I stalled. It generally occurred while idling or at times of slowing down(pulling into parking lot). It would immediately start right up without hesitation.
Now it is becoming more frequent( multiple times in short trips & 95% of all trips to store!) & takes longer to start, today was over 10mins after it stalled. Also, it now will cut out while driving at any speed, don't have to be slowing down or idling. In addition, to the fact that it will also cut out while driving, but while I am pulling over it kicks back in & I'm driving again!!! ??? Also, today it stalled as I went over RRtracks & seemed to happen as we hit the bump???
Shortly after noticing the initial stalling(which was so weird and infrequent I wasn't sure it wasn't something I did accidently without realizing) It was parked in my driveway &cold, when I noticed it sounded like it was running....the fan turned itself on. I had to disconnect the battery to stop it, even then when I reconnected the battery it was still on.
Last thing, don't know if it is related, but the dealer did mention when we changed the fan relay switch to make sure to use rivets. My boyfriend, who was a mechanic for 15years had already done the job &we weren't worried that it was in with screws. The dealer had suggested though, it could cause electrical shorts? Is it as simple as putting another new switch in, but with rivets? Or is it something completely unrelated?
I apologize if this posted twice???? couldn't find the first one...I dont think I clicked the button.

Just a thought....my 99 with about 126,000 miles had same problem & a Fan relay switch solved it. The dealer said it was a common problem with the jeeps. It was a bit difficult to get to.....behind one of the headlights! Good luck:)
#348 of 1069 95 GC limited 5.2 stalls while driving
Sep 14, 2008 (9:17 am)
I have a 95 Grand Cherokee Limited V8 5.2 with 115K miles. Most recently, the car started to "buck" and then stall after running for ~30 minutes. Sometimes she will start right up and other times I'll have to wait 5-10 minutes before she'll start again. She'll run "clean" for a few days before the problem re-occurs. I had the timing done, belts, plugs, air filter and wires changed along with the fuel injectors cleaned by my local Jeep dealership. Use 87 octane (various dealers) and never let gas fall below 1/4 tank level. Could it be the fuel filter/pump?? I'll never know when this problem will occur??
