#4414 of 4618 Re: Rear passenger door lock noise [drucky] by nj_johnk Mar 15, 2009 (1:14 pm)
Replying to: drucky (Mar 10, 2009 5:30 pm) I have replaced 3 door latches on my 2000 JGC. Seems to be a defect with them. To replace the rear door latch, you'll need to pull off the interior door panel, which is held on with "buttons". There is a tool for popping the buttons out, but you can manage with a couple of stiff putty knifes placed on each side of the button. (You'll probably snap off a few but they are not expensive to replace and you'll get the panel off). Remove the phillips screw in the bottom of the hand grip. Pop the panel buttons and remove interior panel in one piece, disconnect the connecting rods for the lock and door handle and then lastly there are 3 Torx screws accessed with door open that need to be removed. You'll also need to unplug the wiring harness from the old latch and reattach to the new latch.
#4415 of 4618 How do I turn up the idle on my Jeep Grand Cherokee? by clintage Mar 16, 2009 (6:44 am)
Howdy! Welp, i'm a 2000 Jeep Grand Cherokee owner. Does that say enough? I've had electrical, cooling, and other problems out the wazoo. The latest is my jeep cuts off if i'm idle. If it falls below 1000rpms, it acts funny. If falls below 500, it cuts off. So right now, when I come to a stop I have to shift into neutral, break with my left foot while giving just a little gas with the right foot to keep it around 1000rpms so it doesn't shut off.   I know this may be a deeper issue (I've read some other sites talking about air intake, etc...), but if I can just adjust the idle up some and see if that could do as a work around for the time being, that'd be great. I'm just not sure how to do it/where to look. I remember my dad doing this for a car that had the same issue, but that was many moons ago. If this Jeep can just last me 1 more year until it's paid off, I'll be happy.   Can anyone gives some me some pointers on where to look and what to do to turn the idle up?
#4416 of 4618 Exhaust fumes/check engine light in my 1997 Jeep Grand Cherokee Limited by newtojeeps Mar 16, 2009 (6:04 pm)
I need some advice. I just bought a used 97 Jeep Grand Cherokee Limited a week ago. Its been running fine but when I bought it I was told the exhaust manifold was cracked and the VIC said "coolant sensor bad". I took it in for an oil change and to replace the sensor and replace the serpentine belt. The mechanic told me the sensor was fine, but it was running too cool so probably a bad thermostat. Turns out there was no thermostat in the jeep at all and the housing was in bad shape. So they installed a thermostat and a new housing. Now it runs rough, the "service engine" light came on. I took it back and they told me it may take 3 cycles of running for the computer to reset itself with the proper levels. I drove it around for a while and now I have bad exhaust fumes inside! Especially when I run the A/C. I know I have a crack in the exhaust manifold but I didn't have the fumes before todays fix. Any ideas what could be causing this all of a sudden? I know mechanics hate it when you tell them "It didn't do this before"...but it didn't! Any ideas would be much appreciated. Replies to this message: frumunda (Mar 17, 2009 2:30 pm)

Replying to: newtojeeps (Mar 16, 2009 6:04 pm) Ok...so you replaced the thermostat and now the system is probably working like its supposed to...now that the coolant is being regulated the ECT(engine coolant temp)sensor is finally noticing that the coolant is either getting warm/not getting warm and is sending that information to the ECM(engine computer) telling it "WHOA!! Its not running rich/lean enough!!! ADJUST! ADJUST!). I'm thinking that now your mixture is running too rich and thats why you are smelling fumes...through the LOVELY cracked manifold. What makes matters worse is that with that crack, the manifold can suck in oxygen, thus leaning out the mixture at the O2 sensor and tricking the ECM into thinking you're running too lean at the injectors...ergo, too much fuel and a really nasty odor. It can also cause your catalytic converter to start loading up and deteriorating. This is what I'd tell your technician. Its like the snake that eats its tail. If you need me, send me an email at brianjoe69yahoo.com. I'll help you more if need be.   Brian

Replying to: trek87 (Dec 14, 2005 2:04 pm) just a long overdue update in case anyone searches and finds this thread...the squeaking was my serpentine belt. it turns out my belt tensioner was worn out and had to be replaced. the squeaking was due to improper belt tension. a simple repair.   went ahead and replaced all 4 shocks and man, what a pleasant improvement on all-around ride and handling (esp. on turns - not nearly as much lean). well worth $40/mopar shock.

Replying to: trek87 (Mar 18, 2009 4:07 pm) is that $40 for the set or $40 per shock? Replies to this message: trek87 (Mar 25, 2009 5:15 pm)

Please help its our only vehicle Replies to this message: neb1997 (Mar 27, 2009 1:47 pm) mtbventana (Mar 28, 2009 10:06 am) sixdays (Mar 28, 2009 10:23 am)

Replying to: axe101x (Mar 27, 2009 1:30 pm) I had this issue. Mine would chug like this when passing and eventually when I was just driving down the road normally. It was the o2 sensor. I think the part was the upstream sensor, located before the cat/converter. The part was around $70. Go to a autoparts store and use their computer code reader. You should be able to pick up an error code if the sensor is bad.   The chuggin freaked me out and I'm so happy it's gone.
