Just wanted to see if you ever found out what was wrong with your Jeep?
 
I have a 2004 Grand Cherokee Special Edition Laredo. Sounds like I have a similar problem like yours but mine is misfiring in cylinder 1.
 
We replaced the coil and spark plugs, and then found out wrong "type" of spark plugs. My husband replaced the spark plug #1 on Saturday with the correct one, even though I think they all should have been replaced. Engine light went out but only to come back on today.
 
He also noticed my reservoir for the anti-freeze/coolant was empty. He just put some in about a month ago, when he put the new spark plugs in. No leaks on the ground/white smoke coming from the tail pipe.
 
I'm taking it in for inspection tonight since it's due, hopefully, they can tell me what is wrong with it.

I also have a 2004 jeep grand cheorkee limited I brought used in 2009. Six months later I had to replace the engine. And now 7 months later my engine light came on reading a misfire in cylinder 7 i took it back to the dealership I purchased it from who also replaced my engine at my exspense of course. It's been there almost two weeks and they have yet to tell me whats wrong. From the reasearch I have done I think it's my head gasket too. I am waiting to get a confirmation of that and than I am going to do more reasearch because something is not right with this suv, I have had it one year 9 months and I still owe on it. Something is just not right. What did you find out about your issue?

my jeep needs an engine according to mechanic. It overheated and apparently there was no water in radiator. Its frozen. first of all hes charging me 1,800 to replace engine.Prior to this the computer kept stating coolant engine low. I would put water in it. Then it would say coolant sensor bad. It had been saying this for months now. I would put water in it. It was also dripping water from bottom, but i kept putting water in plastic container that connected to radiator. Thats when it broke down on the freeway. My husband told him to take as long as it takes. Has anyone had this done and is the price reasonable and how long should the duration be for repair. any advice. I would appreciate it!!!

First after checking and replacing all normal PM parts, Fuel Filter, Plugs, Cap, Wires AND AIR FILTER, if this does NOT cure the hi-load sluggishness, its your Catalitic Convertor. Replace it - or eliminate it.
Best test - most economical - is to disconect eahaust engine side of convertor and go do your hill climb.
Gonna be a bit noisy but if this cures it your Convertor is what is called BLINDED - Plugged.

#617 of 729 2000 jeep cherokee sport 4.0 High oil pressure by jerry2070

Oct 26, 2010 (9:20 am)

I changed the oil put in 20w-50 after that i noticed the first 15 min of driving the oil pressure shot up to 80psi after 15 min the oil pressure is normal so I changed the oil back to 10w-30 put in a k&n filter and it still does it, could I have messed up the sending unit or is the oil relief valve stuck I had a new oil pump installed 2 yrs ago

I am not positive about the 94 model, but on the 95 there is no EGR on the 4.0.

I just got through putting a rebuilt engine into my 95 Grand Cherokee and found through lots of frustrating trial and error that the 4.0 will run marginally with the distributor a tooth off. This is due to the tip of the rotor being about a half inch long and the timing being controlled by a delay or advance in the firing of the coil. The thing is, when the spark advances too much (at around 3000-3500 RPM) the spark fires to the wrong post on the distributor. This causes major backfiring and a loss of power. While trolling for answers on the internet I found several posts that said that it would not run if the distributor is a tooth off, so I figured that this tidbit of info would be handy to post.

#620 of 729 1994 Jeep Grand Cherokee Door Issues by binners

Dec 20, 2010 (1:30 pm)

Hi. Got the Jeep from my dad. He apparently had problems with the driver door, because it looks like the bottom hinge has been re-welded back onto the door itself. Now, the weld has broken off, and the door doesn't close all the way. My husband had to take the bottom pin out of the hinge, just to get the door to drop into place. It still does not close all the way, but now, the interior lights stay on. I have taken out the fuse for the interior lights, but the console reading lights, and middle console light stays on. Aside from disconnecting the battery, which I have done, how can I get the lights to stay off so it doesn't drain the battery? I am afraid to open the door again, for fear of not getting it to latch so I can use it for transportation. Any suggestions would be greatly appreciated!!

#621 of 729 2007 Grand Cherokee CDI codes: p0087,p0088 by fitz4u

Dec 21, 2010 (8:18 pm)

Good Evening:
I'm looking for some assistance with the above codes. They are the result of the Electronic Throttle Control warning and check engine like coming on. I've been able to reproduce the codes and warnings with hard acceleration, but also with steady city cruising.
I've reset the codes, numerous times, and also had the codes and check engine light reset themselves!
I've run fuel dryer, and fuel conditioner twice, because i thought I picked up a tank of bad diesel, without results. Latest has been to replace the fuel filter. The codes apparently refer to high and low pressure at the solinoid on the fuel rail. Of course Chrysler won't just sell the solinoid and would prefer I spend $1000 for a new fuel rail.
Has anyone run into this issue with the diesel?
your assistance is appreciated.
