I know it's crude, but there's really no other way to describe it. 3 times in the last 30 days the KJ has made a noise best described as a 'fart noise'. It is relatively soft, about 1-1.5 seconds long, and kind of a trumpet like sound to it ... a short low 'D' note if you will.

Anyway, I have no idea where it's coming from. I'm having no luck recreating it (yes yes ... insert your bean joke here). Twice I heard the noise while driving in a strait line at a constant speed, once I 'think' I heard it while the Jeep was off and parked in the garage. Does anyone have any serious ideas of what this might be before this topic goes too far down the wrong path?

I go camping alot and I noticed when tenting anywhere near where the libby is parked that it would make some weird noises every couple of hours - almost like a soft compressor like sound for about 1-2 seconds near the rear of the jeep?

This has happened dozens of times and it's loud enough that now I tent a little further away.

My KJ has that sound at the rear too. I'd like to know what it is just fer the heck of it.

Purge solenoid.. It Checks for leaks in the evap system. Ive heard mine kick on a few times when I was outside working and such.

I believe its on the front of the gas tank.

All of the 2007 Jeep models come with a lifetime supply of Beano to counteract this defect
