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

#5048 of 5133 2004 Jeep GCL temp gauge high when heat is on by lijeepowner1

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?

um yeah with the heater on that needle should NOT move! it is normal for it to do that when you run the a/c but not the heat, you need to have that looked at...and if he says its fine, slap him in the face and go to a new shop....

Jan 28, 2012 (7:56 pm)

okay, so this will sound a little weird, but i'm gonna throw it out there anyway... i have '93 GC Laredo with the 4.0L engine and SelecTrac transmission, which i leave in 2WD 90% of the time, unless i'm off in the toolies. i bought the car in late 2007, and the first two years or so i had the car, it was getting something around 15mpg city, and 25-28 in freeway driving, but it idled real rough, stumbled, and sometimes stalled. the rough and stumble went away as soon as the throttle came off idle, and it ran fine as long as i wasn't stuck at a stoplight too long. anyway, i took it in in august of 2010 for repairs, they found a vacuum leak, which they fixed, and now the idle is much better - still not super smooth, but better. but my mileage now is down around 11-12 in city and 18-19 on the highway. my driving habits didn't change...
 
the fact that i was getting over 15 city/25 highway tells me the car is CAPABLE of that kind of performance. how would fixing a vacuum leak cause it to drop like that? more to the point, how can i get it back???

#5052 of 5133 Jeep Grand Cherokee 1997- Door locking problem. by dageorgiu

Feb 01, 2012 (1:48 pm)

So i was givin a jeep to me from a friend last week, and been fixing this left and right on it. So my last problem that i cannot figure out to fix, is that my driver side door wont lock, (and the door actuator is dead i know i have to repalce but not worring about it now) it closes and stay closed but when i put the key into the door and turn it to lock it. it turns (but it bounces back a little bit, it doesn't feel it clicking when u make that full turn) but doesnt lock.. does anyone know of a DIY write up w/ photos plz if possiable. on how to fix this problem. or know what i need to replace to make this door once again lock.
 
Thanks.

The vacuum leak added more air to the engine creating a leaner air-fuel ratio. Result is better mileage but poor emissions. The rough idle was caused by the computer trying to adjust the emissions and not finding a setting, so it was doing a cha cha. I did the same thing on purpose to get mine to pass NJ emissions. Pulled a pair of vacuum lines for normal running and hooked them up to pass inspection.

that's a little like what i thought, but i never had any trouble getting it through emissions (though a leaner mixture usually helps). is there a way a shop or dealer can reprogram the computer to obtain better mileage? or do i just need to create an "artificial" vacuum leak to get that mileage again?

A shop may or may not do it since it may be a violation. You can always ask. My inclination would be to pull a vacuum line again and try that for a while and see how the mileage and performance changes.
