Okay, well to update you on what I've done to it since my last post, I've put new plug wires, a new battery, and a new fuel filter in the jeep. It still dies after 15 min of running. I do have the intermittent check engine light after I let it get to the point of dying. Upon close inspection of the exhaust system, I have a severely damaged exhaust manifold (as in a huge crack that fills the engine and cab with exhaust in about 15min). Since there's an O2 sensor directly downstream of this leak, I think that might be the issue. I've ordered a replacement SS manifold with gaskets off ebay for like 80 bucks free shipping. We'll see if this does the trick (fingers crossed). Thanks for the suggestion. If this doesn't work, I'll definitely check out the O2 sensors. My jeep is the V6 version and the sensors at O'Reily's are like $60. Still, that's money I don't want to spend unless I have to.

My guess is you have an operating pressure problem that for some reason, does not become significant until the tranny fluid gets hot.
 
Make sure you have absolutely no leaks, especially the trans cooler lines. They should be bone dry. I believe leaks affect the pressure.
 
I think you can rule out an electrical fault.
 
I have a 97 and believe it or not Autozone had new trans cooler lines in stock. They were a pain, but not to bad to replace. You may need a spcecial tool to disconnect them at the transmission.

My dash lights up with all the waring lights from time to time. I took it to AutoZone and they put a scanner on it and told me my EGR Valve and Senor are bad. I cannot locate the parts for my Jeep and now questioning weather that is the problem. My Jeep runs fine. Hope someone here has and idea.

I trade my car for this the buddy said the oxy sensor needed to be replaced and muffler put back on. Muffler hasn't been put on yet. Several people said it could different things. It idles kinda ruff at times, stall twice as i was driving it, when you go to step on the gas it bogs out and acts like it wants to stall. Going up hill is a no go, on big hills it will almost come to a complete stop cuz it has no power at all. We replaced the throttle post sensor, oxy sensor and the fuel filter, still no better, its a 318 v8 and the check engine light is on.. Any idea's??? Putting the exhaust on it today.

does your oil look milky?is there white smoke coming from exhaust?take your radiator cap off and look at the coolant in the radiator wile it is running(do not do it with hot engine make sure engine is cool or you will get hot coolant on your face)if you see any of these things you have a blown head gasket/cracked head. but no its definately not because of your o2 sensor or muffler could be a clogged cat may soo look for a clogged cat all the symptoms i listed then if non of that helps do a compression check

Jan 23, 2012 (7:53 am)

Our 2004 Jeep Grand Cherokee Laredo (V6) check engine light came on during our first cold spell about two weeks ago. Mechanic said he saw code for "heater failure" but kept it all day and it ran fine. Mechanic also said they checked it over and could not figure out why the light went on because it was running perfectly fine. All gauges were fine and no fluids leaking or low. Needed an inspection for NYS so I had to wait 30 miles and drove it 60 miles in a week with no problems. Had inspection done a week ago and it passed. Last week, noticed squeaky belt noise on idle at traffic stops a few times but chalked it up to extreme cold again as car ran fine. Today, put on heater and noticed a slight burning smell when I exited car. Got back in car five minutes later and noticed nothing leaking. Got back in car, turned on heat and noticed temp gauge just starting to creep from dead middle to slightly right but not higher. Turned off heat and it started to creep back down and stay left of middle. Now I am paranoid there is a problem. Does this sound all normal or am I correct in suspecting an issue?
