#409 of 439 Evaporative System Issues
Jun 29, 2011 (6:47 am)
Since December 2010, my check engine light has come on five times. I've included below what was done each time at the mechanic.
73,797 - P0456 Error Code - Evaporative emission control system leak detected (very small leak) - 11/26/10 - Possible loose gas cap, mechanic tightened and tested cap and reset the OBD.
74,102 - P0442 Error Code - Evaporative emission control system leak detected (medium leak) - 12/7/10 - Gas cap tested bad, mechanic replaced the gas cap and reset the OBD.
77,718 - P0455 Error Code - Evaporative emission control system leak detected (large leak) - 5/31/11 - Possible loose gas cap, mechanic tightened cap and reset the OBD.
77,865 - P0455 Error Code - Evaporative emission control system leak detected (large leak) - 6/10/11 - Mechanic replaced the evaporative vent solenoid (solenoid was clicking loudly on the 11/26/10 date) and the crankcase vent hose (hose was cracked); reset the OBD.
78,161 - P0455 Error Code - Evaporative emission control system leak detected (large leak) - 6/21/11 - Mechanic suggested going to the dealer because they have an advanced computer system.
I've researched this on Google and it appears that many have had this issue on different Chrysler vehicles, many with no resolution. My mechanic said he could do a smoke test (pump smoke through the evaporative system) to see if that shows anything, but he said that this can be expensive to track down the problem. The dealer wants $95 just to run diagnostics (which would apply to my estimate to get it fixed, assuming they figure out the problem).
Have you heard of this? If so, what have people tried?
Any other suggestions?
The mechanic said I could drive with the light on, but this makes me uneasy, especially if I go out of town. I have noticed a decline in gas mileage. Other than that, it may run slightly rough here and there, but overall doesn't seem phased by this issue. I haven't spent a ridiculous amount of money so far, but I'm trying to keep the costs down on this.

It is a 2002 Jeep GC with almost 79,000 miles. It is the 4.0 I-6 and is two wheel drive.

#412 of 439 1997 Jeep Grand Cherokee Laredo--making "whooshing" like noise
Jul 20, 2011 (5:09 am)
Just noticed this a few days ago, but I am a paranoid driver and hate driving a vehicle when something "could" be wrong.
Anyway, I noticed, what seems to me, a whooshing, air-like noise. The noise seems to come from right up front, around the dash. I can turn the car off and the noise is still there.
My husband drove it the last couple days and he says he can hear the noise but not sure what it is and other than the noise it runs pretty well. Any ideas what this could be?

I had that same sound on my 93 and 95 cherokees and was told that the cause was the air conditioner. don't completely understand the science of them but the coolant in the air conditioner is just flowing back into the compressor and nothing to worry about.

hey, did you ever figure out that noise. my jeep would make the same clicking/grinding noise from the rear so i sat in the rear passenger seat and with the door open and my seat beat on i leaned out of the jeep while my dad made that slow left turn and noticed it was louder outside the jeep right near the pass. rear tire. long story short. i found my muffler pipe was loose and seen the spot where it would bang against at every left turn. i guess the rubber boot or mount on the muffler hanger went bad... replaced it for $9.00 at a local autoparts store. no more embarassing noise when turning left

Low to medium pitched growling noise from somewhere in the front end which occurs only while the vehicle is in motion. Noise is most noticeable below 40 or so but is present at essentially all speeds as well as both on coast and acceleration. Noise disappears entirely when the vehicle is turned even moderately to the left and increases in severity when turned to the right.
